    I'm hoping someone can help me. I run NAV and SpySweeper. A couple of weeks ago NAV AutoProtect started finding and quarantining files flagged as "Trojan Horse" every morning. At first it was a dozen or so, but the daily number has been increasing. This morning the AutoProtect has been running for over an hour and there must be hundreds flagged. Every file flagged has exactly the same properties: the location is always C:/WINDOWS/Temp/DWH[four chars].tmp. NAV also reports the files as being of type "broweser Cache" with a description of "Internet Browser Temporary File Cache". NAV reports the file is both quarantined and deleted!

    Now here's the part that really has me concerned. When I restart the PC I'm getting pages and pages of blue screens with messages that the system is trying to locate these files.

    In addition to NAV and SpySweeper I've runned scans from TrendMicro and Ewido and everythings reports clean.

    Any idea what may be going here and what I can do to correct. The increase in the number of these files being found has me really concerned. Thanks.

    Hi and Welcome


    Your best bet at present is to runt he below and attach the logs requested as this will help our malware experts to find the cause of the multiple trojans and help you remove them and the first parts of the guide in the cleaning stages should remove all the junk for the temp locations which seem to be housing a few of the nastys that are giving you those alerts.


    Please follow our standard cleaning procedures which are necessary for us to provide you support. Also there are steps included for installing, running, and posting HijackThis logs as attachments.
    • Run ALL the steps in this Sticky thread READ & RUN ME FIRST Before Asking for Support
    • Make sure you check version numbers and get all updates.
    • Very Important: Make sure you tell us the results from running the tutorial...was anything found? Were you unable to complete any of the scans?...Were you unable to download any of the tools?...Did you do the on-line scans as suggested? etc.
    • After doing ALL of the above you still have a problem make sure you have booted to normal mode and run the steps in the below link to properly use HijackThis and attach a log:
    Downloading, Installing, and Running HijackThis

    Make sure you also rename HijackThis.exe as suggested in the procedures. Use analyse.exe for the new name. This is very important due to some new infections going around.




    ​
    • When you return to make your next post, make sure you attach the following logs and that you have run these scans in the following order too:
      • CounterSpy
      • AVG Antispyware log - ONLY IF NEEDED you were not able to run CounterSpy
      • Bitdefender - from step 6
      • Panda Scan - from step 6
      • runkeys.txt - the log from GetRunKey.bat
      • newfiles.txt - the log from ShowNew.bat
      • HijackThis
    NOTE: You can only attach 3 files in a single message so it will require that you use two messages to attach all of these logs!
