-- >> What is a virus?

Definition:
"A parasitic program written intentionally to enter a computer without the users permission or knowledge. The word parasite is used because a virus attaches to files or boot sectors and replicates itself, thus continuing to spread. Though some virus's do little but replicate others can cause serious damage or effect program and system performance. A virus should never be assumed harmless and left on a system." -Symantec


A functional definition of a computer virus must include the fact that it creates damage to the computer system "infected"; either inadvertently or deliberately. This definition is somewhat simplified and does not cover all virus types, but is sufficient to show the major differences between viruses and so-called "Trojan" programs, which is that the virus replicates, but the Trojan program does not.

Many of us are computer users. (I bet you're using one right now!) Whether we are systems analysts or just home users, the fact that we have access to computer technology gives us a good reason to become aware of computer viruses and the precautions to take to keep from being infected.

Answer 3

A virus is just a program that students are taught when they are learning ot program - they learn how to make them and how to make programs to diable them.

Go to Start and run msconfig - deselect all programs that are not Microsoft in the Service and Startup tabs - if you see any programs relating to connection to the web, leave them selected. Reboot your PC and see if you can connect. After this, you'll have to update your anti virus software or download a better version from Limewire.com

If all else fails, you might have to format your hard drive and reload everything.

hope this helps
