I am trying to install Symantec AntiVirus Corporate Edition on a Gateway Pro. with a P3 and 256MB. It seems to install fine and even detects the server with the definitions. But when the scan runs, after about 5-6 min. it crashes and reboots the pc. When I sent the error to Microsofts site, it said that the PC detected a hardware failure. Why would a virus scan cause a hardware failure? Is there any way to get the virus scan to run? We have been getting alot of viruses and I'm the only IT guy here so I get all the flak. Please give me some ideas, I'm desperate.
