Significant CPU increase after installing McAfee 8.7 (patch 2) on Windows 2008


Last week we deployed the new McAfee 8.7 virusscan software.
After the installation we noticed that some servers got slower. Especially our SCOM environment suffered from this increased CPU usage (SCOM being a CPU intensive application itself, didn’t have enough CPU time left to process all agent traffic). This ultimately ended up in not being able to monitor anything.

Here’s an image of the increased CPU usage (this is our SCOM report server):

As a quick workaround we decided to do a rollback to McAfee 8.5.
Here’s an image of the decreased CPU usage:

So what’s causing this? No clue yet, but there are some McLogEvent errors in the eventlog (crashing McAfee):
