If you get random popups you have malware on your computer.
The programs freezing as you described are also indicative of that.
Run Adaware and Spybot from safe mode - update them before you run them.
Following that that I suggest you post a “HijackThis” log for expert assistance with your problem.
Read the pinned post in our “HijackThis” forum, herehttp://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/ Carefully read and follow all directions explicitly.
Following instructions run a log, and post it in following HJT forum, at this linkhttp://www.bleepingcomputer.com/forums/posthjtlog.htmlDo not as yet attempt to fix anything by yourself using Hijack This as even what may seem to be a small mistake can render your op system inoperable.
Some files when in one folder may be fine while in another may be malware.
A member of our HJT Team will analyze your log, make recommendations and offer assistance.
It may take a period of time to get a response to the log you posted because the members of our HJT Team are kept very busy. Please

Once you have posted your HJT log, please DO NOT make any additional posts in the HJT forum thread you created until you get a response from a member of our HJT expert team.

A team member, looking to see if a reply has been made might well assume another HJT Team member is already assisting you and might not open the thread to respond.
