hello josam, and welcome to the forums. If you could click on the 'prework' link on my signature and follow all the steps, you'll come out the other end with two logs, one from AVG and one from
HJT. If you could ATTACH both of them in .txt format, that would be great, and I'll parse them for you.
There is a pretty high chance that this is malware related, so I want to rule that out first. If it's not, we'll start looking at other causes, but this has all the earmarks of a malware infection.
No worries, we'll get you fixed up.
