[READ] Most computer problems.
This thread will help most users, except for those with a hardware error, fix their PC.
Lets say for example you downloaded something, and you got a virus.
this "virus" could be Malware/Spyware/trojans. Most of those can be removed
with these programs.
SUPERAntiSpyware
Malwarebyte's Anti-Malware
AVG 9.0
But, with some problems, the virus blocks these programs, and your internet access. This can sometimes be fixed with booting in safe mode, but thats even a hassle. So this is what I have learned with my experiences with viruses.
DO A SYSTEM RESTORE!!
Start -> All Programs -> Accessories -> System Tools -> System Restore.
This will solve most if not all of your computer problems.
