There are circumstances ComboFix will hang
or stall at various stages
due to malware interference
, failure to disable other real-time protection tools or the presence of CD Emulators (Daemon Tools, Alchohol 120%, Astroburn, AnyDVD) so that it does not complete successfully. Also, depending on how badly a system is infected, ComboFix may take longer to complete its routine than it normally does or fail to run properly. While that is not normal behavior, it is not unusual. In such cases, it is helpful to know at what stage ComboFix stalled/crashed and to provide that information to the Helper who is assisting you so they can investigate. Using Task Manager to stop ComboFix's related process usually is enough to abort it.
Open Task Manager
and look for the following ComboFix related processes (some have a .3XE extension):
- any file that has the extension *.3XE except CF*****.3XE <- do not end this process
One at a time, right-click and select End Process
. If doing that did not free ComboFix and allow it to continue, then you will need to reboot the computer manually.
Afterwards, please do NOT run ComboFix again. If you need further assistance with a malware infection, please follow the instructions provided above and post your log in the Virus, Trojan, Spyware, and Malware Removal Logs section of BleepingComputer.
