DOS screen trying to run UDj4ABg.exe - then blank screen

Recommended Posts

One account on the PC is infected even after running MALWARE BYTES and Norton full scans and reboots.


Other accounts are OK.


When attempting to log in, we get a DOS screen that says '... cannot run ... find ... UDj4ABg.exe .. not a system file... '


Then the screen is blank. Mouse pointer responds and cntr-alt-del works to change user.


When starting TASK MANAGER, the following processes are running (first 3 are on my work PC too so are OK)

1) taskmgr.exe

2) winlogon.exe

3) csrss.exe

4) dwm.exe

5) pctstray.exe

6) atieclxx.exe



the following may also be running: taskeng.exe (daughter read these off to me and she might of gotten confused.


Any thoughts?

If you can still login try the following. If not try to start in Safe Mode (tap the F8 key when starting) and see if you can run it from Safe Mode.

Please download Malwarebytes Anti-Rootkit from HERE

  • Unzip the contents to a folder in a convenient location.
  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  • Wait while the system shuts down and the cleanup process is performed.
  • Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click Cleanup once more and repeat the process.
  • When done, please post the two logs produced they will be in the MBAR folder... mbar-log.txt and system-log.txt
