1. I don't see anything unusual. Antimalware is part of Windows Security, updating definitions and scanning for malware. It's normal that it will be quite active for a time after boot. 2. Unused RAM is wasted RAM. You want the RAM to be used, as that will help your computer's performance. RAM that is sitting there unused doesn't help anything. Windows will manage when it needs to unload items from RAM to accommodate more urgent processes.
