You mentioned using Hijackthis and not seeing anything strange. Unless you have been trained in what to look for, I would not recommend that you rely on your own observations. While most of the entries are legit, others could be malware related without you realizing it.
If the above scans do not help I suggest you read and follow all instructions
in the pinned topic titled Preparation Guide For Use Before Posting A Hijackthis Log.
When you have done that, post a log
in the HijackThis Logs and Analysis Forum
, not here
, for assistance by the HJT Team Experts.
It may take a while to get a response because the HJT Team members are very busy. Please be patient as they are volunteers who will help you out as soon as possible. Once you have made your post, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have no replies as this makes it easier for them to identify those who have not been helped. If you post another response, a team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.
