I have the same problem as this guy: http://forum.avast.com/index.php?topic=120789.0
. I created a new thread because as guy who answered in the thread I linked said, the steps are unique for each PC!
I've already run OTL for the first time as explained in the thread I linked ("with Scan all users", "include 64bit scans", "LOP check" and "Purity check" and the code pasted into the custom scans area). And it produced the anexed OTL file.
I checked the folder and it didn't produce any Extras file this time.
I've already tried malwarebytes to remove it, with no success.
Also, if that helps, I have dual boot on my pc with ubuntu...it might help if there's some removal step involved, to circunvent anything the malware did that keeps me from removing some file!
Thanks in advance
