I've recently registered on this great site because i was experiencing some problems with my laptop. I got all the help i could wish for and am very gratefull for that. On one specific step of cleaning my computer i had to use combofix and after the scan completed i was not able to open any programs because i got the error message:
"Illegal operation attempted on a registry key that has been marked for deletion"
First of all: Most of the programs are in fact still able to open using 'run as administrator'
Second: Googling this error i found a lot of references to this problem and even on this site it has been mentioned many times. I did found that no one really could give an explanation for the error but it seemed to me that it was encountered a lot after doing a scan with combofix. I know not very much about computers but logic is logic so i suspect there might be a link between the two. That's why i have a couple of suggestions for those people who take their time in helping others.
1. When you get the error (some suggest it would be mainly a vista problem), you can still acces most of your programs by rightclicking and click run as administrator.
2. If people encounter this error it might be helpfull if asking if they used combofix before the error.
3. With me i could (temporarally) resolve the error by restoring my system to the restore point that was made by combofix before the scan.
I have no idea if this is helpfull at all or even if i posted it at the right place, but if it is helpfull i can feel proud i did something back for all the free help you guys give
