Hi there,
My Symantec Endpoint Protection finds Trojan.Gen.2 in a .tmp file (most recently DWHCC2C.tmp) on a more or less daily basis. I'm having this issue on both a Win 7 desktop and a Win 7 laptop, but let's just deal with the desktop for now. The problem started approximately 6 months ago, and I've been ignoring it because it was not causing any noticeable performance degradation and I haven't been able to afford any downtown for serious removal efforts. The original infection came through a USB drive at some point, and likely was reinfected several times before autorun was disabled on these machines. All USB drives *should* be clean at this point, unless malware can survive a quick format. At any rate, I ran your READ & RUN ME FIRST on the PC yesterday. Logs are attached--I apologize I did not save the HitmanPro log as it came up with no hits at all. I am happy to run it again, however your instructions also indicated not to repeat any steps unless specifically instructed to do so, so I haven't re-run HitmanPro at this point. At any rate, after completing the R&RM steps I began a full data backup to an external 1TB drive. Autorun was off on the PC and the only visible file on the TB drive was a hidden System Volume Information folder (it had been quick-formatted by a clean Win XP laptop immediately prior). This morning when I arrived at work SEP auto-protect had logged Trojan.Gen.2 in the .tmp file I mentioned above--something I see basically every morning, as I said. Many thanks in advance for any help you can provide, ~TBC |

Welcome to Major Geeks!
Run RogueKiller and run a scan. After it finishes the scan, select the Registry tab and then select any of the below that exist and then click the Delete button. Quote:
After reboot, run a new scan with RogueKiller and save a log as in original instructions and attach the new log. How are things working now?

Deleted the indicated registry entries, rescanned and attached log as indicated. It wasn't until after the first couple of tries that I realized which entries you were referring to, as the naming in RogueKiller wasn't obvious to me at first.
I'll keep my eye out for any further AV hits and will post back if they occur. Unless I get one before I leave work today it will most likely not be until Monday--but hopefully it'll be all clean. |

Looks good now.
If you are not having any other malware problems, it is time to do our final steps:

Unfortunately the infection is not gone.
When I arrived at work today I had the same Trojan.Gen.2 notification from SAV. I reran RogueKiller just now (redownloaded it via the link on MajorGeeks because it alerted me to a new version). The same Adobe Speed Launcher entries I deleted previously were back, so I marked them for deletion. I am attaching logs from both before and after deletion of those entries. |

Are the below still showing up on new scans? C:\Users\Jared\AppData\Roaming\service1043.exe) -> FOUND [SUSP PATH] HKUS\S-1-5-21-1277685125-4187367947-72843683-1000[...]\Run : Adobe Reader Speed Launcher (C:\Users\Jared\AppData\Roaming\service1043.exe) If yes, please do the below. Please do the below so that we can boot to System Recovery Options to run a scan. For 32-bit (x86) systems download Farbar Recovery Scan Tool and save it to a flash drive. For 64-bit (x64) systems download Farbar Recovery Scan Tool x64 and save it to a flash drive. Plug the flashdrive into the infected PC. Enter System Recovery Options from the Advanced Boot Options:
On the System Recovery Options menu you will get the following options: Quote:

Yes, those two entries are still appearing on new scans--see the RK log attached.
Followed your instructions, see attached FRST log. |

Download this >> fixlist.txt
Save fixlist.txt to your flash drive.
Run FRST64 and press the Fix button just once and wait. The tool will make a log on the flashdrive (Fixlog.txt). Please attach this to your next message. (See how to attach) Now boot into normal Windows can continue with the below. Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator). Then attach the below logs:

Requested logs are attached. As always, I will have to wait to see if SEP reports anything over the next couples of days before I know whether I'm clean or not. I will report back on Monday.

Your logs are clean again. If the infection comes back again, you are going to have figure out what you are running or which website you are accessing that is bringing it back as it has been removed twice now.

Hi again,
Thanks so much for your help with this so far. I appreciate your concern that my logs have come back clean twice now, and yet the infection keeps returning. However, the very last thing I did before leaving work on Friday was to run the Farbar fix and MGTools scan and post them here. I then left the computer on over the weekend, and when I returned what I saw is shown in the attached screen shot. I visited literally no websites at all, and did nothing at all, with the computer between posting those logs and getting the AV result you see in the screen shot. The computer is in a locked office, so unless someone in housekeeping or engineering or one of my colleagues is manually reinfecting it (enormously unlikely), I'm either being reinfected over the network or the infection was not removed in the first place. Please don't give up on me here.... |

The only USB drive was the one used to run FRST, I did leave it in over the weekend and it's still in there now. There are two network drives normally mounted, both from the same server which is an Ubuntu box I maintain. However, I've been replacing the RAID array in that box with larger drives, and the server was off the entire weekend so nothing could have spread over those drives.
See attached for the details screen of the trojan.gen.2 auto-protect result that was waiting for me this morning. And no, I'm not experiencing any malware problems, but that doesn't mean there's not something here.... This rig is running a quad core CPU at 4.7 GHZ and has 16 GB of RAM, so it's unlikely I would experience a noticeable slowdown. |

Are you sure I'm clean? The logs may have looked that way immediately after cleaning, but see the attached RK log I ran just now.... This is hardly my specialty but it seems to me I'm being reinfected somehow.

Well your other logs were coming up clean. Let's try a few things including a few more scans to dig deeper.
Re-run RogueKiller and run a scan. After it finishes the scan, select the Registry tab and then select any of the below that exist and then click the Delete button. Quote:
Now goto the below link and follow the instructions for running TDSSKiller from Kaspersky
And we will add one more new scan to help us determine if anything else is hiding. Please download OTL by OldTimer.
Then attach the below logs:

All requested logs are attached.
My apologies for the delay, please do not mistake it for disinterest or any lack of appreciation for your help. I had some serious issues with my RAID array after your last post that had to be dealt with, and required multiple (very time consuming) rebuilds and back-up of several terabytes of data, so I was unable to reboot the machine for quite some time. By the time I had all that done there was also a substantial backlog of (also time-consuming) analyses that had to be carried out, again preventing a reboot. Thanks so much again, hopefully we can nail it this time! |

You're welcome.

Okay this last RogueKiller log was clean. I just see some minor tweaks to finish off. Now shut down your protection software (antivirus, antispyware...etc) to avoid possible conflicts.

I had two trojan.gen.2 warnings from my AV when I came in, so I reran RogueKiller before following these instructions to remove the two service1043.exe hits we've been seeing every time. Then I followed the rest of your instructions, and logs are attached.

Okay but this log does not show it. Are you saying it comes back again after the next reboot?
