I got as many other people yesterday several false positives on Trojan.Backdoor.MRX.

For me, it was in these to folders and I have deleted them from quarantine:



Can it affect my computer in the future that I got them removed?

Thank you in advance.

Can you please run the following scanner and post back the logs so we can see more what's going on with your system.

Please create an mbam-check log:

  • Download mbam-check.exe from here and save it to your desktop
  • Double-click on mbam-check.exe to run it, it should then open a log file
  • Please do not copy and paste the entire contents of the log into your next post, instead please attach the log CheckResults.txt file which should now be located on your desktop to your next post

Please run the following scanner and send back the logs.

Download DDS from one of the locations below and save to your Desktop



Temporarily disable any script blocker if your Anti-Virus/Anti-Malware has it.

How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Once downloaded you can disconnect from the Internet and disable your Ant-Virus temporarily if needed.

Then double click dds.scr or dds.com to run the tool, on Vista or Win 7 right click and select Run as administrator

Click the Run button if prompted with an Open File - Security Warning dialog box.

A black DOS console should open and run for a moment.

    When done, DDS will open two (2) logs:

    1. DDS.txt
    2. Attach.txt

  • Save both reports to your desktop
  • Please include the following logs in your next reply: DDS.txt and Attach.txt
    You can ignore the note about zipping the Attach.txt file in most cases.

Getting a bit late for me but maybe one of the Researches can chime in after reading the logs or if not then I'll try to get back to you sometime over the weekend if I can.

Last night mbam quarantined one file with Trojan.Backdoor.MRX. I read about the false positives on this forum, and that the problem had been solved in the new database, so I updated the database and ran a full scan overnight. However eight more detections were found.

1. If these really are false positives, why am I still getting detections and what should I do next?

2. On the scan result screen, does remove mean quarantine? Since I don't need these eight files, I'm inclined to remove them even though this may be a false positive. My options are remove selected, ignore, save log, main menu, exit. If I remove them does it just delete those files or does it make changes to the registry as well that I might regret?

3. I would look at the mbam help files but I'm concerned about navigating away from the scan result screen.

Other info:

I also run Eset NOD32.

Yesterday, before these detections happened, I downloaded a free open source utility called winmerge from winmerge.org via sourceforge.net. Although I tried to check it out before downloading it and it seemed safe and well reviewed, it makes me very wary since I have never downloaded an executable, at least not for many years.

Thanks, Shadowwar. Here is the log file. The 8 most recently affected files are not on my boot drive. (I'm not sure about the one that was detected originally, no log file was created.) These 8 are on my F drive which is an internal drive but is not used to install programs or for the OS. In this case, would it be OK to remove them? I'm not feeling comfortable saying Ignore.

Can you please zip and attach one of those files being detected. Also if you can run a scan in dev mode. Instructions are here: http://forums.malwarebytes.org/index.php?showtopic=3228

I wouldnt remove these yet. They arent in memory and i am pretty sure this is a false positive. I just need this extra info to narrow it down on my end. Also please try to update one more time and rescan the f drive.

Corrected post with additional question (sorry, working from alternate device away from computer):

Sorry to be dense, here, but how do I handle the open scan result window? If I leave it open and scan in dev mode, will that be ok? Or are you suggesting I click ignore? To zip, do I buy winzip from winzip.com or is something built into Win 7 or ...? Also, to be prudent, should I not use the computer until this is worked out?

Sorry, Rich. I am getting confused here. Here is a second affected file. Please use this one instead.

In the first one I sent, I thought I had compressed s1vo.1 but I see that the zip file is s1vo. Since the folder contains two files s1vo (7KB uncompressed) and s1vo.1 (3550 KB uncompressed), I am wondering if I accidentally compressed the wrong (and therefore unaffected) file. However, it may be that the compression doesn't completely use the original file name. At any rate, please use the file I have sent here (Memeo_Sync_setup).
