As of right now, my father's laptop has been infected with this malware for the past three days. As of right now

-Cannot boot in safe mode (loads drivers, then reboots)
-Cannot use the internet (I've tried turning off the proxy through LAN settings but it automatically returns to the setting
-Cannot load the task manager
-Cannot delete the folder in APPDATA which contains some of the files
-Cannot delete the folder located in PROGRAM FILES
-Some registry values of the virus are non-existent on my computer (I was able to open (i can open regedit before the malware boots up through auto-run)
-Cannot open any .exe files
-Cannot Run Antivirus Software (Malware AntiBytes, Spybot Search and Destroy, AdAware)


Please Help. I've tried but i can't seem to get any progress on this virus, and i want to avoid a full Reformat of the hard drive,
