Short of cash or just tired of paying too much for protection needed on today’s internet--try the AVG free virus control. This shareware program works wonders. Provides a relatively fast scan and cleaning and will help you find any type of virus on your computer.
The site is updated continually(just as Norton@othe paid virus tools) and you will get a tool which will keep the scourge of the net away from your computer. I used this program for 4 years and never had a problem--even when new viruses were launched AVG was immediate with their fixes.
AVG Anti-Virus is fully compatible with the new Microsoft Windows XP Service Pack 2 ... the status of their anti-virus protection is superb. To see and read more go to the link at the bottom of this review. This is a must have virus control for all cable and full time hook up people. A protection you can trust for free and it truly works.
