Do give us an update on the results of Malwarebytes Pat. It will be interesting to find out.


Malwarebytes didn't find anything either.

I updated the database of signatures and scanned again.. still didn't find anything.

I scan pretty often with multiple programs... a couple of days ago they both found and isolated something, but I don't remember what it was. It's possible that the damage was already done at that time, and I didn't notice it. If so, it would explain why nothing was found yesterday... the trojan may have already been removed before I discovered the symptoms.

However, most of what was encrypted by the trojan was BIAB files, and I had done a complete reinstall of the USB hard drive after finding and removing the previous threat.

So my gut feeling is that its still there but my antivirus is not finding it.

When I searched online for the telltale phrase "HELP_DECRYPT" all the hits were just a few days old, and many of them indicated that their antivirus did not detect it.
