It sounds like you have multiple malware problems going on with your computer so I suggest posting a HijackThis log in the HJT Logs and Analysis Forum. Here is a link to that Forum: HJT Forum
Please follow the preparation directions and try not to alter your system until you receive help from one of our HJT Team Members. The preparation directions are found at the following link:Prep Guide for Posting HJT Logs
Make sure to follow every step in the prep guide because the scans you are instructed to run will help alleviate some immediate problems.Please note: Do not try to fix any problems with HJT yourself. This is an advanced tool and requires expert analysis.
It may take a couple of days before a helper can get to your log so please be patient; they are very busy but once they get to you, you'll be on your way to having a totally malware free and secure PC.
I hope this helps you out!
