I'm going to stick my nose in here as well - I'm seeing this too.http://forums.mcafeehelp.com/showpost.php?p=550864&postcount=25
I'm going to go out on a limb and say that (once again) this is something on McAfee's side - since so many of us are seeing it at the same precise time. Front Line Tech Support are quite simply, not qualified to give useful information in such circumstances, as anyone who's read my threads will know.
ExBrit - can you update us after the conference call please? If you look at my other post on the other thread, you might find it useful.
When forcing check for updates:
1) spinning icon as usual
2) status: "downloading"
3) becomes status: "McAfee VirusScan" - with incremental percentage
4) gets to 100% and icon disappears and reappears for installation procedure as per normal
5) sits there "installing" for a few seconds, then disappears.
Bad push on the DAT I reckon - I've seen something similar while ago with previous versions of VirusScan - in which the 'install' component of a SuperDAT had been omitted - so it would download, but never could install.
I'm going to say hang tight until tonight's/tomorrow's push - but I reckon it's gotta be a bad push from McAfee's side. Either that, or something on MS Patch Tuesday has caused issues (also not unheard of!)...
