Andy,
I since have changed to Norton. McAfee DID NOT catch it... until I scanned from their clinic... My program indicated my updates were current and my computer virus free, yet when I ran an online scan -- only then was the virus detected. (so I got mad and switched! LOL)

I use Norton Utilities anyway... so the switch intergrated several vital utilities. BUT I WILL in a heartbeat, return to the McAfee online scan if I am concerned... one thing I learned in college (and never forgot) was:

A COMPUTER IS ONLY AS SMART AS ITS OPERATOR.

and the kakworm is smarter than me!
