One of our client's laptop is not allowing me to open the command prompt or registry editor. If I open "Run" from the start menu and type in either "cmd" or "regedit", the screen goes blank except for the wallpaper and then restores without opening either item. I did some research on the issue and in most cases people were suggesting a possible malware/spyware infection. However, I have run several scans with various tools and have found nothing.
I came across a post on another site suggesting that they had fixed the same issue by running an application called ComboFix while in safe mode. I have done some research on this application and found that it can be dangerous due to its aggressiveness.
I was wondering if anyone had any suggestions on possible causes of the issue I described and/or is able to help me run ComboFix on this laptop properly, without causing any damage.
