All my Games started to lag after installing AVG, I uninstalled AVG Still lags, help?

[Falconsight]

An hour before, playing my games totally fine, 60fps, downloaded and installed AVG, now cant even get 20fps.

Any help?

Things to try:

1) reboot
2) open Task Manager-> Processes to see if a program is using your CPU heavily (CTRL-ALT-DEL)

3) Set a Restore Point, then rollback to your last restore point to see if the issue goes away (again, make a restore point BEFORE that so you can jump back)
4) Reinstall the VIDEO DRIVERS

5) Open Device Manager and see if a conflict or other error symbol shows up.

Uninstall avg and try a different antivirus.
I don't know why it should cause a problem though.
