I run a program called
Registry Mechanic, every night. Every single time, it picks up like 8 Microsoft Antimalware entries, which it identifies as the highest kind of security threats.
I feel like Registry Mechanic is a good software--it was recommended to me at #computerhelp on irc.undernet.org, a long time ago, by an op that never steered me wrong, otherwise--, so I feel like I should give the issue due attention.
The entries are: 4x "HKEY_LOCAL_MACHINE\software\Microsoft Antimalware" and 4x "HKEY_LOCAL_MACHINE\software\Microsoft Antimalware\setup\RememberedProperties"
