    Virus Def: 5371 - Trojan (M.exe) not being picked up

      Scan Engine - 5300.2777
      Virus Definitions - 5371.0000
      VirusScan Ent. Workstation -

      Hi all,

      Need big help. I have been searching for the last few days for more info but nothing is turning up. Somehow a trojan has made it's way onto the network and Mcaffe is not picking it up. I'm not sure how it was brought in but it seems to attach itself to a USB using a basic autorun file (as below) and installs also on the target machine. I also provided the hash from the program.

      Once the usb is entered it autoruns the program into tasks as hidden. I have found a little program that kills explorer, wipes the task then allows me to remove the files from the usb but I need to stop it from being transferred. Can anyone help as I couldnt find anything on the forums so far and can someone tell me if all my definitions are up to date?

      Big thanks!!

      M.exe # be3dfda91fe675c4ee7e3dcd0a631306:177766:32771

          Found this showing that McAffee does not pick this up but others do. Is there a way to alert them to this, I noticed a note saying they don't patrol these threads. ADMIN??

          • 2. RE: Virus Def: 5371 - Trojan (M.exe) not being picked up
            i have exactly the same problem with a trojan in dan.exe.
            i had to remove it with an eval copy auf another anti-virus.

            they responded within 7 hours, mcafee webimmune did nothing til now.
            i send them the file 4 days ago.
            i very disappointed about that...
            • 4. RE: Virus Def: 5371 - Trojan (M.exe) not being picked up
              Thanks Tonyb99, I had not come across that in the FAQ's. Must of not looked hard enough. Well I took your advise and uploaded the file noting the other AV's that have picked it up, Webimmune came back as inconclusive.

              To D-Fens, who were you saying replied to you in 7 hours? I had submitted my problem also via the web help last week and my response came this morning which was to take screenshots of; add/remove programs, program files folders, task list, task bar programs, McAfee about screen & system tray.... Will see how WebImmune responds. Thanks guys.

                avira (www.avira.com) responded so fast. i was informed of every step til they included the definitions into the DATs.
                it scored very good at http://www.av-comparatives.org/ , thats why i tried it.
                in comparison to mcafee, its also quite fast...

                i wish mcafee could update their DATs a few times a day, like almost every other AV company does.
                i already asked mcafee about that, they responded that they will release an emergency DAT as needed, but thats not what i wanted to know wink i remember that with engine 5200 it's possible to have inter-day updates...?
                especially no updates of DATs on the weekend are a pain, my company is opened on weekends ;)
                they should at least update the DATs in the morning on mondays or something like that.

                about webimmune: i have no response from mcafee about my trojan, and right now there's no update on that.
                my spam-filter is disabled, just to make that sure ;)
                four days after i sent the file via the webimmune webinterface to mcafee,
                i wrote an e-mail to virus_research@avertlabs.com with my analysis ID to get a status report on that or maybe even an extra.dat, but nothing happend.

                i need a fast responding AV-company, so that there is no impact on the daily business.
                right now, mcafee is not what i expect from a major AV-company.

                not to mention the performance with patch 6 and VSE 8.5i.
                hopefully patch 7 fixes that in october :)

                  Ahh Avira.. Just yesterday I made a linux boot usb AV scanner using their engine and definitions from the recovery iso available on the net for free. Picked up my trojan no worries.
                  Rescue ISO

                  I actually agree with your points on McAfee, at times the service feels a little below par when comparing against other major AV companies on the market. Also my webimmune analysis, like yours, is without reply so far but I might also try my luck with the research address. I am sitting without an update an resorting to re-imaging and manually removing the trojan from usb's although they are getting infected quicker than I can remove.
                  • 7. RE: Virus Def: 5371 - Trojan (M.exe) not being picked up
                    hi troywedy, look at the new comparison on http://www.av-comparatives.org published yesterday.
                    AVIRA scored very good! i bought a antivir license yesterday, to get rid of 1 trojan and 1 keylogger which AVERT didn't update yet. (i sent them the trojan 7 day ago and the keylogger 5 days) you can use the with the command line scanner available here: http://www.avira.com/en/support/support_downloads.html
                    maybe you could use the command line scanner via netlogon to make the removal more comfortable?
                    • 8. RE: Virus Def: 5371 - Trojan (M.exe) not being picked up
                      They do a nice bootable CD there on antivira (see prev link aswell)

                      Avira AntiVir Rescue System
                      The Avira AntiVir Rescue System a linux-based application that allows accessing computers that cannot be booted anymore. Thus it is possible to repair a damaged system, to rescue data or to scan the system for virus infections. Just double-click on the rescue system package to burn it to a CD/DVD. You can then use this CD/DVD to boot your computer. The Avira AntiVir Rescue System is updated several times a day so that the most recent security updates are always available.

                        Hey D-Fens i did check that out after you said, I'm quite happy with what I have used of it. Also McAfee finally updated to DAT 5384 as of 1030 yesterday to include my trojan although I am still weary as it will not pick it up on a direct manual scan, only when the trojan is trying to execute or bind itself. Eiter way it is stopping it from auto running and I have re-imaged all pc's. Thing is my webimmune has still not been updated and no response from the emails I have sent! Pis Poor.

                        Thats the one I used tonyb99, but from this link it has the files to extract and create the bootable usb drive. It scanned my trojan no worries and was quick.
