Confirm it is actually dwh****.exe   not dwh****.tmp

Re: Trojan.gen.2 Problems

Norton finds the files as dwh****.exe and leaves it as dwh****.tmp after quarantine. However it is continuously detecting files as dwh****.exe.

I am sure I had a strange look on my face when I read that

ANY other user other than the thread starter is not to use any instructions, scripts or proceedures,  The work though in cleaning a system is individual and only for that system due to a number of factors.

Unfortunately, with the amount of threads means the waiting time is longer, Norton continually Blocking files won't hurt your system but is is just annoying, Please wait and be patient.   I am  trying to keep up, spending hours here to script and clean machines on a first come/first served basis. If you or someone adds to your thread It will be pushed back in line due to the new update.  I use the boards in reverse to what is seen

Please do not run any tools unless instructed to do so. 

  • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability. Do as the instructions ask nothing extra or run things twice
  • If I ask a Question just answer it, don't run anything unless it states.
  • Major steps used:

1. Find

2. Break

3. Destroy

4. Cleanup  (including system as a whole)

Please read every post completely before doing anything. 

  • Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.
  • Logs from malware removal programs (OTL is one of them) can take some time to analyze. I need you to be patient while I analyze any logs you post. Please remember, I am a volunteer, and I do have a life outside of these forum, (sometimes )

  • Attention to detail is important! Since I cannot see or directly interact with your computer I am dependent on you to "be my eyes" and provide as much information as you can regarding the current state of your computer.

 

Although zeroaccess is detected I have had to remove more than that on machines, like a Bootkit, BCD fix, partition removal, FakeAV and any other objects as a total clean up.

Re: Trojan.gen.2 Problems

I really don't want to touch that.

The detection(s) could be a False Positive fos MS Products and Symantec, or it could be the other realtime products you have or have had, left overs for AVast, AVG, some registry tool on boot, IOBIT etc.  

IOBIT have even created it's own registry backup of hives.

Re: Trojan.gen.2 Problems

From Symantec   (seen in SEP 12 at times also

"The .tmp files are created by the Symantec Endpoint Protection (SEP) or Symantec AntiVirus (SAV) Quarantine scan. The scan is normally initiated by a virus definition update.

There are also several known methods to work around the issue:

  • The quarantine scan on virus definition update can be disabled in the  Symantec Endpoint Protection Manager (SEPM): edit Antivirus and Antispyware policy > Windows Settings > Quarantine > General, under "When New Virus Definitions Arrive" choose "Do nothing".
  • Items in quarantine can be deleted.
  • If the indexing service is enabled it could be triggering the issue when the dwh***.tmp files are indexed."

Re: Trojan.gen.2 Problems

Hello,

Are you running a Norton Antivirus OR Symantec Endpoint Protection (SEP) ?

If Symantec Endpoint Protection, then what version of SEP?

I would suggest you to work on these 2 Articles:

DWH***.tmp files are detected in the user profile temp directory. 

http://www.symantec.com/docs/TECH92399

When new virus definitions are in place and the quarantine is being scanned, a DWH file is created and detected by Auto-Protect

http://www.symantec.com/docs/TECH102953

Hope that helps!!
