This issue is already been reported to the McAfee Product development team & they are working closely towards the resolution of this issue, hope this should be fixed soon.
I will keep you posted on the resolution status once that is done.
I appreciate your patience and co-operation.
It appears that Mcafee has gone through a couple of software updates. The issue has not been resolved. Is there any hope that Mcafee will really work on this problem. If I have a particular file I want to scan, I will be out of luck unless I scan the whole computer. When I want to scan a file, Mcafee will spend several hours to scan the computer where the file resides. Surely, at the end, I will get the file scanned. It is a scarry thought that it will take serveral hours to scan a file This will make Mcafee not good at all.
I found an other problem. After the automate software update, Mcafee keeps saying the real time scanning is turned off. I turned it on and it turned it off by itself. It appears Mcafee wants to play game with me. The only way to get around it is to un-install and re-install Mcafee. This is not cool at all.
