Hi!

 

Today i wanted to do some cleaning on one of laptops at my dad's house. I runned Rkill, then AdwCleaner. Once it rebooted i runned Combofix. Everything was going fine, until it hanged (and it's still hanging). You can see what happened at the "screenshot". It's been like this for over an hour and i don't know what to do with it. I would rather not damage anything.

Could you tell me what's the best thing i could do?

 

Thank you.2i92n95.jpg

This is one of the reasons why we recommend not to use ComboFix on your own (see here). There are risks involved and we would prefer it if someone (a trained expert) who knows how to resovle any issues that may arise when running the tool, is supervising it's use.

As a general policy, Bleeping Computer does not offer advice on how to run ComboFix unless we asked someone to run it or if there is a problem with the computer caused by running the tool. When issues arise due to complex malware infections, problems running ComboFix or with other security tools causing conflicts, experts are usually aware of them and can advise what should or should not be done while providing individual assistance. Those attempting to use ComboFix on their own do not have such information and are at risk when running the tool in an unsupervised environment.

With that said, there are circumstances ComboFix will hang, crash 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. Usually using Task Manager to stop ComboFix's related process is enough to abort it.

Open Task Manager and look for the following ComboFix related processes (some have a .3XE extension):
  • PEV.exe
  • NirCmd.3XE
  • PEV.3XE
  • SED
  • GREP
  • 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 unless asked to do so by a member of the Malware Removal Team.

If you need further assistance with a malware infection, please follow the instructions in the "Preparation Guide" starting at Step 6.
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running DDS which will create two logs. (Note: Windows 8.1 Users will not be able run DDS and create a log)
  • When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts.
