This is a double post
Original Topic is Here
You had a virus on your system that was never fully cleaned and checked by malware techs in Malware Forum. This can cause the issues you are having as well cause more and even repeat problems to occur.
First please do not double post as this will create confusion with the Tech staff.
Second since you do have a active malware or virus issue
Please go to the "Malware Forum" link in my signature below and follow the instructions at the top
Especially the "You Must Read This Before Posting A HijackThis Log".
That will give you several steps that will help you clean up 70 percent of all problems by yourself.
If at the end of the process you are still having difficulty start a topic and post the requested logs in THAT forum.
Once the malware technicians have cleared out any infection and given you a clean bill of health, if the problem continues then feel free to post back here and we can investigate the problem even more.
