I've had my share of viruses, for the most part, if it's a decent virus, it'll turn off all security features, anything to keep it from loving up your computer.
Best offense:
Open Task manager
Look for a process running that looks like it's made of completely random characters
Go to the file location
Double check to make sure it isn't a core file
End the process, delete the file
Reboot in safemode
Run a system restore to a point where you didn't have any problems, or before that just to be safe.
^Run a full system scan somewhere in these steps
To prevent this stuff from happening again:
Stop watching gay research
Stop going to weird internet sites
Stop downloading gay research
Freeware has a virus attached
Start up every part of your security program's features.
Delete your temporary internet files
