I notice on Quick Scan no green check mark when scan is done on start up programs. I am using Glary Utilities not sure if this would cause an issue.The issue with high ram I believe is caused when signatures update.
Seems it may cause Windows Modules Installer to go into overdrive.Vanished after I uninstalled WAM. I ran it on Windows 10 Home with Defender as AV. Forgot to say that I was running it on Virtual Box not on a production machine.
