Hi,

We have a C# add-in for Excel, which uses web services to communicate with a
Java server. We have real performance problems when McAfee virus scanning is
enabled on the client machine.

When virus scanning is enabled the Excel process takes 90% of the CPU for an
extended period of time. Using processexplorer we can see that the thread for
mscorwks.dll!ReleaseFusionInterfaces is taking all of the time in the
process.

Other posts I've read have indicated that ReleaseFusionInterfaces may be
just the closest export symbol, and may not be where the time is being spent.
In any case does any one have any idea why McAfee would cause the core .Net
framework to consume so much CPU?

This may not be the answer you are hoping for, but in my experience McAfee has caused similar
occurances with other .NET applications frequently as well.
