What is the best and most effective anti-virus and where can i find it?anti virus software

virus is an infection where someone writes a program that will enter your computer and damage your files until your computer burns up. Adware/Spyware is a program written that attaches itself to a file or files in your computer to force it to perform the function the other guy wants - it mostly redirects you to a site for advertising and selling stuff. I just switched to Window Live One Care as it protects and maintains you computer. It is free for a three month trail and then you buy for $49.95 which is about the same as any good program. You find it at Microsoft.com. I have found it to be much much much better than Norton Anti-Virus which had been the #1 program. Norton had become my big brother and would not let me do the things I wanted to on my computer and every update had mistakes until one froze my computer and I had to reload. I had been mad at Norton for years.

Spyware may consist of programs that "Spy" on you. They get the info on what web sites you visit to popping up ads on you computer without you wanting them.
