If you have read my previous post about symptoms of virus infected computer, then now you are sure that your computer is infected with viruses or not. There might be a case where an internal software problem has happened and you might consider it as virus attack. Any way either problem created by the software or by the computer virus, it’s always safer to scan the computer.

After you are sure that there is a virus in your system, first thing you need to do is disconnect your system from the internet. There are many viruses, worms and Trojans which activates only when you are connected to the internet system.

Now download free anti virus software from the internet. Check out top 10 best anti virus programs. I suggest you to download trial professional version and not free version now. I am saying that because professional version has always higher detection ration than free version. You also need to download latest virus definition database. I’ll prefer to download kaspersky anti virus because I like it the most. Burn it to CD. Now install it on your system.

If your system is so badly infected that it doesn’t boot normally then you should try booting your system in to safe mode. If it’s not booting in to safe mode also then take some professional help.

After your computer has become virus free, consider purchasing anti virus software and use it. As it’s said prevention is better than cure, it’s always better to stop virus from entering in to system than removing it afterwards.
