Six Signs Indicating That Your Computer Has Been Hijacked

Rootkit is a collection of malicious software programs that allow a hacker to gain privileged access to a computer. It is classified as a virus and presents a big risk to computer owners. Malware (i.e. Malicious Software) is called a Rootkit if it can disable the operation of an anti-virus program installed on a computer and perform its own operation undetected. Since it is not easily detected by an antivirus software program, computer owners are unaware that their computer is infected and their privacy and security is being breached.

Malware operating in your computer can do several unpleasant things with it.

Some of the most important ones are:

a. It can cause your computer to infect other computers on a network.

b. It can capture passwords and credit card information and transmit it to criminal organizations.

c. It can use your computer to initiate internet denial of service attacks on some organizations operating their businesses online and inhibit their operation.

d. It can use your computer to initiate internet denial of service attacks on some organizations operating their businesses online and inhibit their operation.

e. It can slow down your computer and severely affect performance of some of its applications.

Since Rootkit is very difficult to detect, you need to be sensitive towards your computer to detect an infection and take preventive measures. Below are several signs that your computer is infected and you should be aware of them to prevent becoming a victim of cyber crime.

a. Your computer becomes painfully slow.

Your computer suddenly takes ages to load and start programs which you were earlier using without any problems.

b. Some programs freeze and do not respond to mouse clicks for long times.

Malware sometimes load and operate key loggers in to your computer that record every key pressed. These key loggers interfere with your mouse/keyboard and the program you use and slow down the messages transferred within the computer.

c. Your antivirus stops functioning without your knowledge.

If you sense that your antivirus is disabled and you start your anti-virus program manually to perform a complete system scan, it does not detect anything. This is a grave warning sign for Rootkit’s existence in your computer.

d. Anti Malware programs such as Spybot – Search and Destroy do not detect anything.

Spybot usually find some issues when it scans your computer. At least, it detects some suspicious cookies and removes them. If it stops detecting anything and tells you that your computer is clean, it can still indicate the existence of Rootkit that might have disabled its normal operation.

e. You get strange messages at shutdown.

Messages usually pertain to files that can’t be closed, or programs that can’t be stopped.

f. Your computer behaves strangely all of a sudden.

If you sense that your computer desktop layout has changed, some icons seem different; some strange files exist on the disk, it might indicate that some Malware resides within your system and has taken its full control.

Rootkit’s are used by cyber criminals to harvest credit card numbers and identities of people. One such organization penetrated by law enforcement agency gained 34,000 credit card numbers from people in several days of its operation. Many computers get infected and are operated as zombies in a botnet.

We are not sure about the exact number of computers getting infected and waiting to be remotely operated on command to inhibit their regular Internet operation.

Currently there are no good tools to detect and remove Rootkit’s. Thus, you need to be sensitive towards your computer and take protective measures if you sense any strange behavior. Antivirus companies are aware of Rootkit’s and have released some dedicated tools to remove them from your computer system. Their problem is that when a computer gets infected with a Rootkit, the antivirus software does not function anymore.

If your computer is infected with a Rootkit:

You can download a known Rootkit removal tool and use it to clean your computer. While doing this, you should run your computer in safe mode.

If the tool identifies and removes the Rootkit, you should download the latest antivirus and perform complete system scan. Many a times, there are other viruses in the system and they can be detected and removed by the antivirus software once the Rootkit is removed from your system.

In other cases, you should consider reinstalling the operating system. Backup your data, (you can use cloud service such as drop box for that) and then reinstall your operating system. Make sure not to use any infected devices with your computer that might infect the system again.

If you have reason to believe that your credit card information was stolen, you should get your credit card replaced from the issuing company. Change your passwords in sensitive services such as bank accounts and PayPal. Once you do this, you minimize the risk of it being used by criminals.

I gained my Rootkit sensitivity when the credit card security called me and asked if I had charged $10,000 on my credit card in the past few days. After reinstalling my operating system, I sensed a new penetration attempt and decided that I need to do something about this threat to make the world a better and safer place!

Protective Eye Wear For Computer Users

Protective Treatment For Computer Users
If you spend long hours on the computer you may experience dry eyes, eye strain, headaches and blurred vision. These symptoms are known as computer vision syndrome and result in various vision problems if some type of protective treatment is not used. The most common type of protective treatment for computer users are computer glasses. Computer glasses are special glasses designed for making working on computers safer and more comfortable and they protect your eyes in a variety of ways.

Protection From Your Computers UV Rays
Although the UV rays from your computer are not nearly as strong as those from the sun, your eyes still need protected from these rays to help prevent cataracts and other eye problems. This is why many computer glasses are made from Polycarbonate plastic which is both light weight and blocks the harmful UV rays from your computer.

Protection From The Computers Glare
The glare from the computer screen can cause your eyes to dry out, result in blurry vision, and even severe headaches in some people. Having your computer glasses treated with an anti reflective coating will reduce the glare from your computer screen and make those long hours spent working on the computer far more comfortable.

Scratch Resistance
Working on and off the computer during the course of the day can result in your putting on and taking off your glasses countless times. This can result in scratches that causes eye strain when trying to view your computer screen. By getting your glasses treated to be scratch resistant you reduce the chances of your glasses becoming scratched with just normal use.

Keep in mind if you wear prescription glasses that your normal glasses are not going to provide the protection you need when doing computer work. In addition, your normal glasses are not designed to allow you to view the computer screen properly as the distance between you and a computer screen is different than your normal reading distance. So getting a pair of glasses specially designed for working on the computer will allow you to see and read the words on the computer easier.

Even if you don’t normally wear glasses specially made computer glasses are still your best choice in protecting your eyes while you are working on the computer as these glasses protects you from both the UV rays and the glare of your computer and result in less eye strain and more comfort.

Remember that you need to protect your vision since it is all you have and once your sight is gone it is gone. So investing in a pair of computer glasses can save your eyesight both now and in the future.

5 Check Points To Consider Before Investing In a Dive Computer

When we start thinking about investing in a scuba computer, whether it will be an upgrade or our first instrument, we will need to consider available investment funds, desirable parameters, future diving career, area of application of this device, and buying options.

Let’s discuss these critical points in deeper details to have clear understanding.

Consider your future path as a scuba diver

Let’s presume that you already know your future diving career, how often you will dive and where, and what will be an area of an application of new scuba computer.

If you are a recreational diver only and dive just a few times a year in tropical waters – probably you won’t need expensive dive computer with advanced functions, and on the contrary – if you dive very often and think about trying free diving or going technical.

If you plan that after sometime you will progress in scuba diving mastership or engage in free diving activities – you need to consider investing in more expensive computer that has multi-gas capabilities, wireless air integration, digital compass, free dive mode, etc.

When you have answers on above-mentioned points – you may make a list of desirable parameters and functions for your next model.

Which specifications are desirable in your dive computer?

Here you need to imagine which features you want to have. These days scuba computers have all imaginable and unimaginable functions and easy satisfy each and every scuba diver! And several of them were mentioned below just for your consideration:

  1. possibility to use some dive computers as fully functional digital wrist watches onshore;
  2. possibility to build computer consoles with submersible pressure gauge and compass;
  3. few dive modes – Air, Nitrox, Gauge, Free diving;
  4. some of them have Dual Algorithm for liberal and conservative diving;
  5. possibility of programming for up to 8 different gas mixes to dive with trimix;
  6. wireless air integration;
  7. adjustable settings of Personal Conservative Factor, Altitude, Deep and Safe stops;
  8. colour display;
  9. PC interface;
  10. dive simulator;
  11. integrated digital compass;
  12. possibility to upload from PC colour or grey – scale pictures and maps into the dive computer;
  13. user replaceable batteries, etc.

I think the best answer about specifications you may give after setting clear your future diving path.

Available investment funds

This part is one of the most important! Dive computers today are packed with many features and we may get multifunctional instrument with several dive modes, dual algorithm, wireless air integration, possibility of programming for several gas mixes, etc. And each additional function may increase price considerably.

When we have come clear with our future diving career and all features and functions – it is the right time to look inside our pockets!

It may happen that after considering every option and selecting the “special one”, we suddenly notice that we are short of money for particular model. We should not worry! Let’s look realistically again…

Maybe we do just fine by having a dive computer without wireless air integration, multi-gas capabilities and digital compass right now, like Mares Puck or Aeris Manta and Cressi Leonardo, Sherwood Insight or Tusa IQ-750 Element II!

These models are user-friendly and reliable dive-buddies with very competitive and reasonable prices in our market these days!

But if your wallet is thick enough and you are planning to progress in your diving career fast, you may want to invest in more expensive scuba computer, like Aeris Atom 3.0 and Mares Icon HD, Oceanic OC1 and Suunto D9tx, Tusa Zen Air IQ-950 and UWATEC Galileo SOL with capabilities of wireless air integration, multi-gas options, possibility of heart rate monitoring, uploading pictures, integrated digital compass and much more.

Buying dive computer from e-bay

Here are few words about this option.

I will not do this personally. I don’t want to make you thinking that this option is worse than others, we all have our own opinions and preferences. Just consider that instrument that was bought from e-bay might have some glitches and it would fail under water – this could bring you troubles! And on top of that – manufacturer warranty may expire by the time of your purchase.

Models without audio alarms and backlight for the beginners

It is my personal opinion only. If you are a beginner in scubadiving – it is preferably for you to invest in model with audio-alarms and backlight in order to be alerted during certain dive conditions.

Beginners do not have that experience yet, which mature divers have, beginners do not know what to expect and when! So, if you are at the beginning of your diving career – select dive computer that has audio and backlight!

After all research we have done so far and considering all options, we have collected all information that we need before investing in the best dive computer, according to our needs, budget and future diving path.

Gramma Goes Techie: The Best Computers for Use by Seniors

As our population ages, so does the age of computer users. Baby boomers and caregivers are one of the fastest growing segments of Facebook and many elders are learning how to use e-mail, games, picture storage and even video conferencing. Seniors want to be connected.

But not all computers are easy for seniors to use; in fact there are very few that are.

I’ll begin by sharing about the computer that I found to be the most senior-friendly, probably because it was specifically designed for seniors. It’s called the Telikin and can be found at their company website.

This computer is a touch-screen stand alone computer. It is basically like a stand up lap top and can be set up in less than 5 minutes. It does come with a mouse and keyboard but because it is a touchscreen (like the iPad), the mouse isn’t necessary.

The operating system is Linux so it is very resistant to viruses. Any software that is needed is preloaded and the company provides free lifetime software updates. Because of this, software such as MS Office cannot be added but the company is getting ready to add an MS compatible word processor. It does have Adobe Flash support (which is one thing that my iPad does not have and that causes me disdain.)

Software includes web access, e-mail, games, video chat (using Skype), a built in webcam, photo sharing using Facebook, news updates, weather updates, a 6 in 1 SD card reader (for adding photos), and a CD/DVD player.

The Telikin has 2 different size screen options: an 18.6″ LCD monitor with a 320 gigabyte hard-drive ( approximately $699.00) and a 20″ LCD monitor with a 500 gigabyte hard-drive (approximately $999.00). Both are also Wi-Fi ready.

One cool feature is that with just a touch, the screen can zoom up to 200% so it is excellent for those with vision problems.

Another feature is that there is a help tab on every screen and there are video tutorials.

But my favorite feature of all is their “Tech Buddy system”. This system allows the senior to give a trusted family member or members their user name and password. If there were to be a problem, a family member can access their computer remotely to check it out. The family member can also add appointments to the calendar, add photos, etc.

Of note is that you might also find this same computer listed as the WOW! computer by the company FirstStreetOnline. They are a subcontractor for the Telekin. At this time, the WOW! computer does not include the Tech Buddy system although the company anticipates adding that feature soon.

Another computer that has been recommended as a senior-friendly computer is the Chromebook.

The Chromebook is a product of Google’s partnership with Samsung and Acer.

There are different models starting at $430.00 with the Wi-Fi equipped versions starting at $500.00. The 3G Chromebooks come with 100 MB of free internet data per month (meaning they don’t require an internet provider service) which is not a huge amount but is probably enough for checking e-mail and gathering photos.

This type of computer system is also protected from viruses because nothing but Google’s built in processes can write to the hard drive. In that regard, it is a great choice.

If your elder does have an issue with the computer, there is the ability for you to “sign-in” to their computer from afar and configure the settings remotely.

To me, it isn’t as user-friendly as the Telekin, doesn’t have touch-screen technology and sometimes laptop screens are difficult for elders to see. But the Chromebook does come with a font re-sizing feature and also something called ChromeVox which reads the tabs as you open them and also the entire content of the screen.

Apple iPads have also been suggested as good computers for seniors to use.

iPads are stand alone tablets, don’t take up much space, have touchscreen technology and are quite intuitive. Objects can be made larger with just the pinch of a finger. And there are plenty of “apps” for seniors to download from the app store – some are free; some are not.

I have an iPad and when I went to visit my mother, she was very interested in it. She especially liked scrolling through the photos.

My problem with the iPad being used for seniors is that there is not a way to add photos from a camera card. The photos would need to be loaded to a computer and then transferred to the iPad once the iPad was connected to it OR they could be e-mailed or placed on Facebook and obtained that way. Sometimes the quality of the photos on Facebook aren’t great because of the way they were originally uploaded (it takes much longer to upload high quality photos to Facebook).

I also think that it would be difficult for seniors to be aware of what apps were available to them (and then, of course, they would need to remember the iTunes password each time they purchased an app.) (My father couldn’t even remember the password to log on to his computer.)

I don’t find that the e-mail system is very easy to use and don’t imagine that seniors would either.

Another problem with the iPad is that it does not work with Adobe so many video features are unavailable and again, software such as MS Office is not compatible with this computer.

That being said, I love the iPad for my own use. It would be a good “toy” to keep certain seniors entertained, as long as you were there with them. There are piano apps, games, on-line newspapers, the Oprah magazine, music, etc. I just don’t feel that it’s the best option for a senior-friendly computer.

There are 2 computer options produced by HP that deserve mention.

One model is the Autopilot. It can be purchased as a desktop ( for approximately $1,125.00) or a laptop (for approx. $1,165.00) and is said to have goof-proof operation.

The features of this computer that impressed me were the “OnTimeRx” medication and appointment reminder software that is included, the high-contrast keyboard and mouse and the Hoyle Crossward and Sudoku puzzles.

The desktop version comes with a 17 inch monitor, mouse and color printer.

There other model is the Vision Plus Model which comes preconfigured with screen magnification software, a high visibility keyboard, an all-in-one printer and a scanner so that other things can be scanned and magnified (assuming the senior is able to operate the scanner).

It also has the OnTimeRx software and retails for $1,255 for the desktop.

Of course, desktops take longer to set up and can be a little more confusing in that regard.

Many different websites and stores carry HP computers.

The last computer I wanted to mention is the least expensive at approximately $549.99. It is the Kiwi PC.

It’s a desk-top and is Linux-powered like the Telikin so viruses are unlikely. It comes with a 19″ monitor, pre-installed and simplied e-mail system, a color-coded keyboard (different colors for consonents, vowel and punctuation marks, although; I’m not sure I like that) with 1″ over-sized keys. There are 2 USB ports in the keyboard.

It comes with 2 GB of memory, a 250 GB hard drive and a DVDRW drive. There is a 1 year warranty on this product.

The one feature that I really don’t like about this computer is that although they offer free system work for Kiwi upgrades, they require that the owner PAY for the upgrade, ship the computer to the company. The company will then perform the upgrade and send it back. That’s not something that would be easy for most seniors to do and almost makes the low cost of this computer a moot point.

So there you have it. I’d love to hear from any of you who have had good (or bad) experiences with any of these computers or have perhaps discovered an even better computer option for senior use.

What to Look for When Purchasing a Computer

Assuming you have not a clue about a computer, a computer unit consists of a tower in which is the central hub for all things technical such as the hard disk or for example the processor, graphics card, RAM, and everything else which makes a computer function. A computer unit also consists of a monitor, keyboard, speakers and a mouse. If you’ve no idea of what I previously mentioned means don’t get your mind in a twist because I will be explaining what they mean and why you’ll need them.

What is RAM?

Ram, as referred to as random access memory is the place in a computer where the operating system, application programs, and data in present use are kept so that they can be quickly reached by the computer’s processor.

When it comes to purchasing a new computer, in this time zone 2GB + of ram is ideal so be sure to look for that amount or anything above it.

New Operating systems typically use 1GB of ram alone so should you wish to actually use your computer and take advantage of it’s over hardware aspects ensure you purchase at least the stated 2GB, preferably more if you wish to do more (Such as multi-tasking, gaming, viewing media, etc)

What is a Processor?

The processor is technically the little chip within the hub of your computer, when I define hub I mean the “Computer tower”. It’s functions are to carry out computations such as adding, subtracting, multiplying, and dividing. Think of a processor like a the human brain trying to calculate a mathematics sum it can be fast or it can be slow. The faster, the more complexed tasks the computer can handle (Such as multi-tasking).

In this present moment of time you should be looking for a Quad Core Processor, these include Intel’s Core Range (i3, i5, i7) or AMD Phenom’s Range. Quad Core processors can handle the very latest of computer software and are essential if one wishes to effectively multi-task.

What is a Hard Disk?

The hard drive is where all of your programs and files are stored, without the hard drive the computer is unable to function. A hard drive actually performs the same as a cassette tape or a VHS tape. The platters inside a hard drive are in most cases made of glass or aluminum and they are used for the writing of data.

The typical person purchases 250GB +, however if you are not very tech savvy and wish to only use your computer to carry out web browsing, reading email, etc anything above 50GB will suit you just fine.

250GB can hold over 46,640 music tracks* (Depending on the songs bitrate and length)

What is an operating system?

Operating systems provide a software platform which on top of them run computer programs, commonly referred to as applications. Without an operating system the computer simply acts as just a shell so it’s important to have one. A common operating system is Windows, windows consists of various version which were developed at different time stages the newer that operating system, the better. Microsoft Windows 7 is the latest of them all (Correct as off 2011)

Windows 7 is the ideal operating system to look for when it comes to purchasing a new computer seeing as it is the newest of all of the windows range plus is simple to use for the not so tech savvy person. Windows 7 is very minimalistic and can be learned very quickly because of it being the latest it is also widely supported and is far more secure then it’s previous range.

What is a graphics card?

Graphics cards take data from the CPU and turn it into pictures. The better the graphics card, the more complex pictures it can display and the faster of speed it can process them images. A good graphics card is usually required when one wishes to use their computer for gaming purposes.

If you have no intention of gaming on your computer and wish to only use it for the use of browsing the internet you should be looking for an integrated graphics chip like the Intel GMA range. These or an alternative branded chip come free with a computer as standard so don’t worry about this.

If you are looking to use your computer for the purpose of gaming, consulting your technical specialist/retailer is advised.

What is a keyboard?

A keyboard allows one to input key strokes on their computer, it can be required when browsing the internet (i.e typing in a website) or logging into your computer.

A keyboard is included as standard when purchasing a computer build in your local computer retailer.

What is a mouse?

A mouse allows the computer user to navigate around the operating system. Within the operating system comes a little graphical pointer which can be moved around to click on things such as icons and files, the mouse controls that graphical pointer. When the computer user moves the mouse with his/her hand the graphical pointer within the computer interface is to move too.

A mouse is included as standard when purchasing a computer build in your local computer retailer.

Massage in Bucharest

Recognize it! You’re busy! And so must be! That’s what life is like! But you want more than that, you want to do more for yourself and massage can help. Because massage makes more than a simple relaxation of the mind and body. It keeps your body in shape and gives you enough energy to make you enjoy a longer life better than you do it today.

Massage releases stress. At the moment, stress is a universal evil. Every time you are late, every time you avoid a car in traffic, every time you have trouble working, stress is doing his job. Each time adrenaline increases heart rate and cortisone levels and organs respond to the measure. You will be in a state of nerves and constant agitation.
When there is no release of stress, serious problems such as an upset stomach, hypertension, sleep disturbances, chest pain, or existing illness may worsen.

Some of the changes that may occur are: Anxiety, lack of concentration, depression, permanent fatigue, muscle or bone pain, sexual dysfunction, excessive sleep or insomnia

All these stress-related problems can be diminished and some can be totally eliminated by massage. The researchers concluded that a massage session can lower heart rate and blood pressure, relax your muscles and increase endorphin production. The massage also releases serotonin and dopamine and the result is a general relaxation, both physical and mental.
Our body care must be at the top of the priorities.
By adding the massage to your routine you will look much better and you will be much healthier and relaxed. Massage can improve your vitality and mood. Massage can prepare for a long and beautiful life.

Our masseuses personalize each massage session according to the needs of the individual.
Our massage parlors offer a variety of relaxation styles and techniques to help you. Apart from relaxing, massage can be a powerful ally in reducing pain, increasing energy levels, improving mental and physical performance

We recommend : HotAngels , VipZone , JadePalace , ThaiPassion

After a massage session, you will see how the mental prospects are enriched, the body allows easier handling, better pressure resistance, relaxation and mental alertness, calm and creative thinking.
When you have the impression or force yourself to stay straight, your body is not actually aligned properly. Not only does the posture look bad, but it forces some of the muscles to go muddy all day, while others become weaker. After a long time, the incorrect position may cause other drops. For example, internal organs press on what affects digestion, breathing ability is also diminished, which means that much less blood and oxygen reaches the brain and hence all sorts of other complications.

Massage allows you to return your body to the track. Allowing the body to make healthy and accurate movements is one of the greatest benefits of massage. Massage can relax and restore muscles injured by bad posture, allowing the body to position itself in a natural, painless position.
Apart from posture, there is also anxiety. One of the signs of anxiety and stress can also be heavy breathing. When the body begins to breathe too little and deeply instead of breathing at a natural rithm, it is impossible for one to relax. One reason may also be that the chest muscles and the abdomen get tightened and the air gets harder.

Massage plays an important role in learning the body how to relax and how to improve breathing. Respiratory problems such as allergies, sinuses, asthma or bronchitis are a group of conditions that can benefit from massage. In fact, massage can have a positive impact on respiratory function.

Many of the muscles in the front and back of the upper part of the body are breathing accessory. When these muscles are tight and shorten they can block normal breathing and interrupt effective breathing natural rithm. Massage techniques for stretching and relaxing these muscles improves breathing function and breathability. Massage leads to an opening of the chest as well as structural alignment and nerve dilatation that are required for optimal pulmonary function. A good way to treat respiratory problems with massage is the taping made in Swedish massage. When done on the back, along with vibrations, it can detach the mucus from the lungs and can clean the airways for better later function.

Massage not only relaxes muscles, but helps people become aware of daily stress levels. Once the body recognizes what really means relaxation, the mind can rest easily relax before the stress becomes cornice and harmful. This will help you enjoy a balanced life. Massage controls breathing, allows the mind to re-create relaxation before the occurrence of chronic and harmful stress and increases the level of energy.
