It only infects 360K floppies. It will infect any new diskette as soon as the diskette is accessed (COPY, DIR, DEL, program load, etc.), similar to the Brain. The virus will freeze the system if a <><><> is pressed and a cold boot is then required. When the virus activates, the first copy of the FAT becomes corrupted. No other symptoms have been reported. The Ohio virus is similar in many respects to the Den Zuk virus, and may be an early version of Den Zuk. A diskette infected with Ohio will be immune to infection by the Pakistani Brain virus.
