I am running a P4 with 256 Mg of Ram. It is running XP Home Edition. I took this drive out of the computer and ran it as a secondary drive in another computer. I ran it through the Master drives Anti-virus. There were a few infected files that I deleted. When I put it back into the original box it still runs very very slowly. Any ideas why this would be happening. It is a fairly new system. After connecting to the internet, I try to update McAfee on this drive and it says it cannot find an internet connection. Should I go to Safe Mode, uninstall McAfee and then re-install it. Any ideas on the speed and why McAfee doesn't update?
