Automatic scan kicked in at 11.30 (the time that McAfee had 'chosen'). At about file no.4900 and 0%, it skipped to 58%, and it now on 82% on file number 6490 (or thereabouts).
There are about 500,000 files to be scanned, so something's not right.
I see that there are 'banner' messages on the guided help pages etc, that say Support are very busy at the moment! Are there issues with McAfee that are causing lots of problems with lots of users?
