Pop-up related issue
 

Is there any software to remove pop-ups? I was trying to download open office yesterday on windows 8 for a school project and it downloaded some software that keeps making pop-ups appear every time I open a new tab, start up a new program ect. ect. So is there a safe program to remove pop-ups?
I removed everything it downloaded along with open office but it's still causing me trouble.

I think I downloaded spyware stuff o.o

Thanks so much! My pc hot cleared up right away ^,^
