I was exploited using the windows xp active X exploit a while back. I read how to remove malware and other viruses with Malware-bytes and did that with no problems. But for the past week or so i have been getting trojans from the same area of my computer, which was in my temp files. I do not know why i keep getting them and they are quite annoying.


Files Infected:
c:\windows\temp\DWH85CD.tmp (Trojan.Agent) -> Quarantined and deleted successfully.
c:\windows\temp\DWH9BD6.tmp (Trojan.Agent) -> Quarantined and deleted successfully.
c:\windows\temp\DWHA1C1.tmp (Trojan.Agent) -> Quarantined and deleted successfully.
c:\windows\temp\DWHA358.tmp (Trojan.Agent) -> Quarantined and deleted successfully.
c:\windows\temp\DWHA52C.tmp (Trojan.Agent) -> Quarantined and deleted successfully.
c:\windows\temp\DWHA991.tmp (Trojan.Agent) -> Quarantined and deleted successfully.

The files follow this pattern each time. DWHXXXX
X=Random digits
and they are always found in the temp folder.

If anyone knows the quick fix to this or just a fix please tell me and thank you.

Please download RootRepeal Rootkit Detector and save it to your Desktop.

* Close all programs and temporarily disable your anti-virus, Firewall and any anti-malware real-time protection before performing a scan.
* Click this link to see a list of such programs and how to disable them.
* Create a new folder on your hard drive called RootRepeal (C:\RootRepeal) and extract (unzip) RootRepeal.zip. (click here if you're not sure how to do this. Vista users refer to this link.)
* Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the Files tab, then click the Scan button.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Note: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

Nothing much found there. Try this scan:

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

When in Safe Mode open Windows Explorer and navigate to the Desktop. You should find the file there.

Sorry for the late reply Budapest, I had to do the scan twice just in case. The unfortunate part is that everytime I wanted to save the log after the complete scan from Dr.Cureit but it would freeze up in safe mode and i am unable to save it.

Fortunately with my scan it found two trojans in my registry which were taken out.

I keep getting the pesky little trojans which are found with MBAM and i want to find the root cause to it.

I did several quick scans on MBAM and it seems that it deleted everything that made the trojans that keep coming back.

Thank you Budapest and everyone at Bleeping Computer for fixing my computer!

If you’re clean, you should create a new Restore Point to prevent possible re-infection from an old one.

Go Start > Programs > Accessories > System Tools and click System Restore. Choose the radio button marked Create a Restore Point on the first screen then click Next. Give the Restore Point a name and then click Create. Then use Disk Cleanup to remove all but the most recently created Restore Point. Go Start > Run and type: "Cleanmgr" (without the quotes). Click Ok > More Options tab > Clean Up in the System Restore section to remove all previous restore points except the newly created one.

Also, go Start > Control Panel and double-click Add or Remove Programs. Post back and report any Java entries that you have.
