Intel GPA not attaching to any process?

I thought this might be useful to Intel Graphics Performance Analyzer users. There is a known issue where Avast anti-virus software blocks Intel GPA from attaching to any process. You can try to disable the Avant software but that usually does not work since the Avast process is still running in the background.

If you remove the Avast anti virus software completely from the Control Panel, then reboot and trying to run Intel GPA again, it should work. We know this is an issue with Avast 5.1.889. Our GPA team is working on fixing this in the next release but till then hope this information helps folks using GPA and are running into this issue.
