We have purchased and run Malwarebytes several times, and each time after the restart, Malwarebytes  STILL reports a Trojan.

Trojan Agent

Memory Process



How can I clean this out?  I recall there being some very strong "medicine" I can use.

Hi Larry,
It is almost never good enough to just run one of the tools/scanners any more - regardless of how they...and MBAM is one of the best.

Please follow the directions in these EE Articles for using a 'rogue process stopper' - and then running your scanners.

PLEASE be sure to post the logs from any tools/scanners you run so we can review the details of what is found.

Boot into safe mode and then remove the trojan.

HijackThis may be more effective:

You can get ageneric report of what HijackThis finds @ http://www.hijackthis.de/
Then use HijackThis to remove the trojan

@Michael-Best -
Most current variants of malware aren't even running their processes during a "Safe Mode" boot and they will be invisible to any scanner - much less something as old and out-dated as "HijackThis".

When Trend bought it from 'Merjin' (orginal developer) the wouldn't hire him to maintain it, so he moved over to the team at MalwareBytes.

Anyone wanting to see the processes running will be better served to run "OTL" (http://www.geekstogo.com/1888/otl-by-oldtimer-a-modern-replacement-for-hijackthis/) - but to run it in "Normal Mode" so that (a) the rogue processes are actually running and (b) they can be identified.

Of course, in most instances running a rogue process stopper and one of the automated tools is light years better than trying guess what to do based on only a scan.

Use Malwarebites and windows security essentials they work very well for me. If that does not work try using Mbam.

This one is quite resistant!  It couldn't be removed by RogueKiller or Combofix.

What's left to run?

If you followed the articles recommended by younghv, you would have run RogueKiller, let it do its prescan, then clicked its Scan button in the upper right corner... when that scan's done, minimize (DO NOT CLOSE/EXIT)  RogueKiller, then do a full scan with MalwareBytes AntiMalware (MBAM for short).

on severe cases, i gain more time by a full reinstall, than by cleaning the system, so that's my suggestion : a fresh install

Good recommendations, but I had a serious problem. I ended up backing up the User files, extracting all the serial numbers, then erasing and re-installing.
