When was the last time the PC completed a windows update ?
Hi, and thanks for responding. I am running Windows XP SP3. The version of McAfee Virus Scan is 15.0, DAT: 6544. I have automatic updates for Windows turned on, so it should be up to date.
It has been a couple of weeks since I first posted about this, and after reinstalling Antivirus Plus a number of times and removing other anti-malware from the system, the problems have become less significant. What I do notice, however, is that mcshield.exe seems to become busier when the computer has been running for a long time (several days) without rebooting.
It seems like I was to quick to conclude that the problems with the real-time scanner had become less significant. Today, after a reboot of the computer, mcshield.exe has once again started to intermittently jump up to around 99% of cpu power for a few (at best) seconds at a time. Do you know if there has been a new update that could have caused this problem? The only change I have made to my system recently is to remove a bunch of old and unused zip files in order to cut down a little on the very long time the virus scan takes to complete...
