DAT 5998 is the most current as of this reply back to you. You might want to try a fresh install of McAfee. Go to Add/Remove programs and uninstall and reboot. Go to Useful Links at the top of this page and run the MCPR removal tool and reboot again.
Follow the instructions on the link and run the McAfee preinstall toolhttp://service.mcafee.com/faqdocument.aspx?id=TS100119
Then login to your online McAfee account and download your software. Let us know how this works for you.
Hi Tom K3TG have done all you suggest in your reply. Now I have no windows/internet connectivity at all and a task bar (s it called task bar - bottom right of screen?) that only emerges bit by painful bit after fifteen minutes. I'm sending you this from another computer. What do I do now please?
