i have a computer that was infected with the av guard online virus. i have tried many things to remove it. i was finally able to remove the fake scanner portion of the virus, but now im unable to run any kind of scans (whether it is online or offline). i've tried every method of renaming files, but once the scan starts, it immediately disappears. there are some registry files that say i don't have the permission to look at them. i believe whatever it is that has my system hijacked has the permissions portion of windows on lockdown. i've spend nearly 2 weeks trying to crack this but have been unsuccessful. please help. thanks.
