A guide and tutorial on using ComboFix
Do not mouseclick combofix's window while it is running. That may cause it to stall.
If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.
Can't Install an Antivirus - Windows Security Center still detects previous AV
We are almost ready to start ComboFix, but before we do so, we need to take some preventative measures so that there are no conflicts with other programs when running ComboFix. At this point you should do the following:
* Close all open Windows including this one.
* Close or disable all running Antivirus, Antispyware, and Firewall programs as they may interfere with the proper running of ComboFix. Instructions on disabling these type of programs can be found in this topic.
Once these two steps have been completed, double-click on the ComboFix icon found on your desktop. Please note, that once you start ComboFix you should not click anywhere on the ComboFix window as it can cause the program to stall. In fact, when ComboFix is running, do not touch your computer at all. The scan could take a while, so please be patient.
When finished, clear away any of the files and folders that were created by ComboFix.
Start > Run, Copy and Paste > ComboFix /uninstall and click OK.
Qoobox is a folder created by Combofix to quarantine any infected files.
