You don't need a new computer. You DO need to get this one cleaned up. Free software or phony virus programs won't help--they just make matters worse.

Do yourself a favor and make sure you have a REAL virus protector in place and keep it up to date. DO NOT use one of the free registry scrubbers or antivirus tools so many here suggest. Some of these are just ok, but far too many are themselves evilware and most of them are pretty flimsy. Some actually implant other spyware, adware or even viruses or trojans on your system and make things worse--far worse. The problem with a weak antivirus program is that it gives you a false sense of security--like Airborne cold-preventer. Using nothing at all would be better as you would be more careful about where you venture on the Internet.

I have not exaustively tested the top-rated dozen or so serious antivirus programs (of the many dozen out there) but PCWorld has; so has Consumer Reports. AVG is the lowest-rated. I would not depend on first-hand accounts from end-users and amateurs but instead, look for opinions from computer _professionals_ whose job it is to analyze these _essential_ programs. Using a free antivirus program is like buying cancer drugs from that guy on a street corner...
