On the internet you can download free anti-virus (AVG or Avast 5, for example), but remember to turn it on and above all, regular updates.

Even better, some anti-virus you can schedule automatic updates. Do it if possible!

The free solutions are interesting … but often limited in their abilities and capabilities. If you can invest a few dollars, you can choose for all solutions in one, these solutions are not just doing their job as an anti-virus to pay, but also has other roles such as anti-spyware, Anti-Backdoor, etc.. . not to monitor incoming mail that is perfectly all while you work on your computer.

But back to this virus. A virus can occur in several ways:

- A USB stick or a CD for example, that someone please loaned you not know that there is an infected file inside!

- For a program from the Internet that you might not be malignant (eg, “Clean your PC completely free with our program”) downloaded

- Peer-to-peer sharing of movies, music, software between people (such as Kazaa)

- Upon receipt of a simple e-mail with an attachment that could have this name: image.jpg.exe (Note the last expansion, it is certainly a well-hidden malware)

To avoid a disaster to adopt good habits:

If you download new programs always run trough your anti-virus software before opening them, and prefer sites that have created the business, especially for software from abroad.

If you download music, movies, make sure that your anti-virus program has an on-site peer to peer, who can often pay for most anti-virus, but if you practice for this type of download, n Do not hesitate to spend a few dollars! If you prefer more certainty pages!

For your e-mail, be sure to avoid the creation of your e-mail with a summary of the news! They are easier to identify e-mails as “Re …” an email response if you do not know the sender?

This is usually the subject of questionable messages.

As a rule never to open a message that you do not know the sender, especially if it contains an attachment.

Once again, anti-virus scan of your mail server and show potential intruders. And finally, never open an attachment in an e-mail, save it and send it to the virus.

Be careful when your computer becomes infected with a virus, it should be rinsed thoroughly to format your hard disk! So remember to regularly back up your files outside!

The most common complaint is the computer slows performance. This is not noticeable at first but eventually you will start to complain. When your computer slows down, it may be because you have not performed routine maintenance appropriate. You may have spyware, a corrupted registry or malware that slows you down. Detect adware, spyware and malware, and clean your temporary files and empty your cache. Clean your registry with a free cleaner, more are available for download. Then you should do a Disk Cleanup by going to Start> All Programs> Accessories> System Tools> Disk Cleanup. Then defragment your PC by going to Start> All Programs> Accessories> System Tools> Disk Defragmenter. Defragging is best done before going to bed and let him work all night. After all this, you must be running much faster and will remain that way if you regularly repeat these steps. Defragging should be done every few months, but other tasks should be used at least monthly.

Another problem many of us have encountered is a computer that turns off or restarts without you started. You will be hard at work or have fun surfing and suddenly the computer restarts or shuts down completely. Irritating as it is, it can have a simple solution. Check that the fan on your computer, it may not work properly or may be blocked by dust. New fans are inexpensive and easy to install, but it is imperative that they are in good condition to cool the computer. Stop is a way to cool off when the fan is not working properly. Your diet can also be in trouble, check the cables leading to your first power source and the leader of the PC card to the exit. If all this is that you can secure a diet that is about to die. You can buy a power supply for $ 25 on site.

If you have never seen the “blue screen of death” you know why it is so called. If your computer throws at you or crashes you can have trouble with malware or spyware. Restart your computer in safe mode and use your antivirus program, followed by your malware detector. If this does not solve the problem you’ll want to update your hardware drivers. If a program can not find the correct driver, it can cause your computer to lock. To avoid these problems, scan your PC regularly and set your device settings automatically update your drivers. Increasing your RAM and virtual memory will also help.

A very important indicator that we have a problem is often overlooked. We connect to the internet and are not taken to our home page as usual, but a commercial site or another familiar destination or we find that our default search engine has been changed or that we are operating in another browser . If this happens, you have been hacked! There is no need to panic, but you must run a scan malware, spyware scan and then your antivirus software – in that order. Chances are that will be enough to quarantine or remove spyware that was installed on your computer. But how do you have such malicious intruders? You probably clicked on a link in an email or a social network, something you should never do especially if it claims to be a link to your bank or another site that contains your personal information. You can avoid most of these problems by not clicking on those links, even if they are sent by someone you trust.

Finally, I’m sure everyone has had problems with their PC after a power failure. Most of us have surge protectors, but sometimes that is not enough to protect our computers. Power surges, spikes and voltage problems, common during summer thunderstorms and winter power outages and can cause damage, data loss and other problems. The ideal solution for this is to install a UPS (uninterruptible power supply). You can get a basic UPS for about $ 50. When your power goes out the UPS kicks in and keeps your computer running until you can record all the important information and close properly.
