I don't like McAfee either. But this it's deployed and wanted by another department in the IT office as they'd like a centralised solution.
I doubt it's causing some programs on many PCs to hang sometimes, specially Outlook. Plus it looks like it's the one that has slowed down some PCs terribly. The problem of the subject of this tread however is unique to a single PC.
Anyway, I am very curios to know what you have to say about McAfee 10.2.
