BleepingComputer.com: Repeated instances of Malware.Packer.Gen with MBAM

Okay, I'm running Windows XP, most recent service pack, etc.

So, I ran a search of with MBAM last week and found on my portable hard drive a Malware.Packer.Gen file. It was in a file folder belonging to an emulator I used in the past and had backed up last summer. Looking through the logs, it seemed like MBAM had found this before in the emulator when it was on my hard drive, but not before I had backed it up on my portable hard drive (I don't scan my portable hard drive as much as I should, I suspect, although I only ever use it with my computer as a back-up system). Since nothing else had shown up on my computer in the ensuing months from the first instance nor after running Norton, SuperAntiSpyware, and MBAM in safe mode to be sure, I chalked it up to a possible false positive as it seemed like Malware.Packer.Gen seems to be the false positive of choice for MBAM after I did some cursory searching of the internet.

I cleaned it and everything seemed to be fine, but then yesterday I was running my weekly Norton/SuperAntiSpyware/MBAM sweep of my computer (not at the same time) and MBAM found another Malware.Packer.Gen file on my portable hard drive, this time in the system restore folder. I cleaned it and ran Norton and MBAM again in safe mode and found nothing. Am I likely dealing with false positives or is something more sinister afoot here?

Oh, my portable hard drive is a SeaGate 500 gb, if that is relevant.

Re: Malware.Packer.Gen

MBAM just found the same nasty in an old (2006) copy of analogx-proxyi.exe that I've had laying around. It's a legit midget proxy server from a legit developer, so I'm pretty sure mine was a false positive.

Yours may be too. Upload the possibly infected file to virustotal.com and see what results you get.

Thanks. Unfortunately I already deleted the files after they were quarantined, so I suppose that makes confirming if they were a false positive a little more difficult (facepalm).
