When I double click on the security center a gray box appears with red McAfee, but that box disappears within a few seconds and nothing happens. Can someone please help?
Sure we are here to help you,
Can you provide some additional infrmation like;
What is the type of operating system we user in the computer?
Do we have any other antivirus software instlled in the system ?
Run mcafee virtual technician from http://mvt.mcafee.com and post me the session id so that I could review the files.
