High CPU Usage From Inteset Process

Has anyone seen 70% CPU usage from the Inteset process?

This is version 2.00.139 on Windows 10.

Please upgrade Secure Lockdown to the latest release found on our website.

OK.

Is there a changelog online which shows what issues are fixed in each release?

It's not online, but there is a Changlog.txt file included with every installation under the c:/programfiles/inteset/secure Lockdown folder.
