Several times I have downloaded updatedDAT files from McAfee for the McAfee Virus Scan 3.1.6. Virus Definition 3.0.3209 on a scan engine that is 3.1.6. I have been trying to unstall a 3211 update. When I doubleclick on the Icon, I get a message that there is not enough Disk space even though I have cleared the Temp. files on my C drive and it is indicated that I have 80% clear space?
