I have EXACTLY the same issue. Similar issues appear on a general web search. None with any resolution that I could find. Following the "knowledge base" directions did nothing.
This guy could have been me. I did all the things he describes doing (except the ccleaner and wiping the files; which may be my next step) with no resolution of the problem.
WHY ISN'T MCAFEE ADDRESSING THIS?
His question was asked almost 4 months ago.
This does not bode well.
Locking thread as old. Either check with support portal or start a new one if the issue still exists, thanks.
