What is a computer virus?
A computer virus is a computer program or computer code that can copy itself onto, and infect a computer without the permission or knowledge of the computer user. This code often attaches itself to various parts of the computer operating system with instructions to change the behavior of the computer. This intrusion is often a destructive one. A virus can delete files; turn off virus protection, crash the hard drive or produce a number of other harmful effects.
A dialogue box on my computer has popped up indicating that my computer may be infected with a virus; click ok to run a virus scan. What should I do?
Don’t click ok! Do not click on the close box either. Hackers can write code to infect your computer if you click on either. The best bet is to hit the following keys ctrl- alt and the delete. Click on task manager. Under the applications tab look for the dialogue box, click on it and end task. On the end program dialogue box, click end now. Immediately after closing that program run your antivirus and any antispyware protection programs.
