MCAFEE SECURITY SUITE 6.0

I just installed McAfee Sec. 6.0 on my system. After running updates for an hour, all the apps included are current. I noticed during reboots that the system would come up normal, but once my regular desktop screen and task bar loaded, there was an almost 3 minute delay before the icons on the desktop loaded. The system is a P3, 1Ghz with 256 mem.

Any ideas what could be going on? I searched the docs, but no help there.

Thanks for the help
