McAfee antivirus won't run scheduled scan or update

I have a dell pentium XP SP3 machine that uses McAfee as only AV tool.

I have updated subscriptions to security center and antivirusplus (though not sure I need both)

When I renewed I selected autoscan- weekly and autoupdates; but I noticed that when reading the scan result log files, only ~1000 files were scanned, even though the big green check mark shows on the McAfee Security center home page saying my system is secure.  I also noticed that when updating, it says it is, but the little meter never moves off of 0% completed. When I try to open McAfee to see realtime updating, page instantly closes.

I uninstalled and reinstalled security center twice, same thing happens.

I downloaded virtual technician, and he says everything is fine; but I suspect not.

When i try a right click scan from my computer icon on desktop the scan may be a little more thorough, up to ~100,000 files, still I believe not complete, as old version before renew would full scan over 200,000 files.

I suspect my system is infected by virus or malware that McAfee is not equipped to remove; or else there is a persistent error in how the new version of Security Center operates on my machine. I have also exp[erienced very slow internet connections, hanging up in office programs (outlook, word, powerpoint, etc) and in task manager CPU usage always at 100%; but I don't know if the McAfee issues and performance issues are related.

I am also concerned that my machine is not protected and at risk for further infection.

Any ideas?

This is new: came down this morning and real time scanning was off, tried to turn it back on, but could not from security center, so I ran VT and he said he fixed it; had to reboot twice.  First time that ever happened.

Ran a file count from command line, there are ~172,316 files on my system. Last full scan made it to 13,000 before deciding that was 100% and eveything was OK.

Post that follow the instructions here reboot the computer and let us know the status of your Real time scanner .

Also, let us know if you have restored the computer to an earlier date (system restore)

Any other new hard ware/software installations done to the PC.

Re: McAfee antivirus won't run scheduled scan or update

After powering down machine and re-starting and using VT  I got McAfee to turn real time scanning back on.

When running VT said DAT was not what was expected, so I manually updated.

This is what I have now:

Since it looks like I am up to date, and real time scanning is back on, the rest of your instructions may be to fix a problem I am not experiencing (today at least).

Still need to see if it auto-updates and can run a scheduled full scan.
