I'm freaking out here. ;___;

Okay, so I stupidly downloaded antivirus pro.
(DO NOT FUCKING DOWNLOAD IT. )
Now, I am having problems with google.
I removed most of antivirus pro.
Now, everytime I search something in google and click a link, it takes me to random site or it doesn't load or it ends up as Loading...
And the stupid 'Your computer may not be protected' warning pops up once in a while.
Can anyone help me?
I need to find out what else to remove to stop google and other sites I use to search to stop fucking up. Please. ;; I don't want to lose my PC.

TRY DOWNLOADING AVAST! ANTIVIRUS, MAYBE THAT CAN FIX IT
IDK, I'LL TRY TO FIND A SOLUTION

Thanks Chris. ;; I have both of that already.

I HAD THAT A COUPLE OF WEEKS AGO.
IT'S NASTY.
CHRIS FOUND THE REMOVER, THOUGH. TOO BAD I DIDN'T THINK TO ASK HIM BEFORE I DID A WHOLE SYSTEM RESTORE. xD

I removed most of them now. ;; Google is still fucked up.
