To assist in your problem, we need you to download HijackThis (http://www.merijn.org/files/hijackthis.zip). Extract it to a folder like C:\Program Files\HijackThis. Run it, and select 'Scan'. Do not fix anything yet, just select 'Save log', and copy the contents of the log to your next post.
An expert will be along shortly to review your log.
Also, although I can't assist in HJT logs, I must recommend that you have it moved to the Security forum.
In the top-right corner of your message is a red triangle with an exclamation mark: Report Post to Moderators. Ask them politely if they can move your post to the Security forum. You'll more likely (and more quickly) get a response.
