There is an issue I hear from posts here that the upgrade process doe snot work well. I would suggest you try the uninstall reinstall path namely follow
to correctly uninstall Mcafee reboot when asked and ryn
and reinstall from your account
This should fix the issues up.
That said there is a continuing issue with action centre giving incorrect messages between 2.5 mins and 5 minutes after boot. This issue clears up at 5 minutes after boot. i assumed your issue was not this 1.
If still an issue best to report this to Tech support ie call them and see what they say.
I have the Same Problem Too. Made a clean install of
Windows 8 pro in december 2012 on a Dell pc. Windows
Security Center allways warns there is no Virus Or
Firewall Protection. Time After Reboot Or Start up PC
Does Not matter. I deactivated Windows Security Center.
Deinstallation and reinstall of mcafee total Protection
Makes no difference.
When You uninstalled Mcafee did you use teh mcpr tool I mentioned above ie windows deletion of Mcafee followed by mcpr?
I had this after new install of the beta 3 installs gave action centre errors and mcafee Real time scanning starting issues as well as greyed out firewall errors.
Running MVT the virtual technician available on the tech support page (see useful links tab above) fixed it.
That said if still not chop call support as they need to sort this issue out asap.
