how to change back (hacked server) settings

This has happened twice in the last few days. What is the quickest way to discard unwanted settings, such as; huge hud, colored letters on profile, more lag bars, etc...?

what exacly did you changed, i need more info

It was the mod server that changed my settings. I usually just uninstall/reinstall everything. But if I could just find where the changes were located, I could change them back. Changes included: The "Create Class" has multi-colored font. HUD/UAV is 4x bigger. Lag meter has more bars. Do u think backup would help me if it were to happened again?
