I might add Avast Antivirus. I have been using it for years on my Win764 PC. I'm not desperate as Avast updates very clean at this point however I really like Patch which I run monthly. It is a real help as I'm rural on mobile internet 3 gig limit and I don't want stuff I don't need. I scrutinized Patch before downloading 1st time and uninstalled 32bit versions of some utilities left over from before I went to IE11 exclusively. Patch now saves my time and data.
