i have had a trojan virus along with pc antivirus for quite awhile now. my computer is REALLY messed up and i am using malware antibytes to delete it. however, the MAIN virus is in system 32 in my local settings in a hidden folder i didn't know about. So, I looked at the report from the scan and i have traced the file, which is where i discovered it was a hidden folder. when i went to delete the virus it says it is being used by another user and cannot be deleted. how can i get rid of this, plz help me.
