I have just installed the latest version of Zonealarm, When I close the computer at night, a box appears headed : MsK Detector and threatens me. An Internet search says this is part of McAfee.

I think that McAfee came loaded on the computer when purchased a few years ago, but I got rid of it at once and have had no mention of it since.

I use Windows XP, Zonealarm, AVG Free, Firefox.

How can I stop the MsK Detector box appearing?
Many thanks.
