I dont have an answer for you, but you read the following:ComboFix usage, Questions, Help? - Look here
Unlike what many people think, Combofix is not a fix-all program that's just "run and done". It is a highly specialized tool that should only be used under the supervision of an expert. It's not an "everyday use", clean-all program.
If you suspect malware, please post a new topic in the Virus, Trojan, Spyware, and Malware Removal Logs
sub-forum, with a description of the issues you are having and the log file. Please note: the Malware Response team are always overwhelmed, and it could take a few days to get your first reply. Just be patient and don't "bump" your topic by replying to it. You will also likely be scolded for running Combofix without supervision.
If you don't suspect malware and just ran Combofix for no good reason, please uninstall it by typing the following into the "Run" box and pressing Enter: combofix /uninstall
In this case, we will try to diagnose your problems here in your original topic.
