You could still be infected or have some remnants left of a 'removed' infection.
To remove your infection I would now like to refer you to the Highjack This (HJT) forum here at BleepingComputer.com. First:
Read the Preparation Guide found HERE
. It is very important that you follow ALL of the instructions found within. Second:
Post your system information along with a brief description of the problems you are having, and your HJT log in the HJT forum found HERE
Please, after you post your HJT log, DO NOT make another post in the HJT forum, until it has been responded to by a member of the HJT Team. The first thing they look for, when looking for logs to reply to, is 0 replies. If you make another post, there will be 1 reply. The team member, glancing over the replies, might think someone is already helping you out, and will not respond. So, just make your post, and let it sit there, until a team member responds. The volunteers who work that forum are very busy, so please be patient and wait for a response. It can sometimes take a few days.
You are in good hands! Good luck!
