Hi ankersj, and welcome to BleepingComputer.
What you are experiencing is why I post the following warning to those using Combofix without the supervision of one of our trained staff members in the security forums.ComboFix
is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use
. Please read Combofix's Disclaimer
. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.
If you have the installation CD for your operating system you can try doing a repair installation. The link that rockmilk posted will take you to a site with instructions for this. A repair installation will not affect you data, photos, videos, and documents. That is if combofix didn't damage any of those non Windows files.
