Malware Preventing All Anti-Virus Software From Running

[enosuomynona]

My computer got infected with some kind of malware this morning that is preventing all my Anti-Virus software from running. I keep getting the message "Windows cannot access the specified device, path, or file. You may not have appropriate permission to access the item."

The malware is also turning each Anti-Virus software's EXE files into hidden write protected files. I tried to go to uncheck the "Read-Only" box in properties and it keeps revert back to "Read-Only", and can't not be uninstalled or deleted.

I also tried to run ComboFix and it seems to get stuck at the screen says "Scanning for infected files.... ", after two hours of waiting there was no further activity.

Does anyone have any information on how to fix this problem.

Thanks.
