Avast Antivirus historically has one of the [highest rates of false positives][1] of all antivirus products tested by [AV-Comparatives][2].  Avast Antivirus also has a history of connecting with Google servers to send analytics.  The latest version of Avast Antivirus defaults to inserting a promotional advertisement into your outgoing emails.  ***That's the final straw.***

Please recommend a [tag:gratis] (free for personal use) [tag:antivirus] tool for [tag:Windows] that meets the following requirements:

 1. Low CPU use during real-time scanning
 1. Low memory use
 1. High rate of detection
 1. Low rate of false positives
 1. No inserting ads into outgoing emails
 1. No intrusive advertising popups or nags on the desktop or system tray
 1. On-demand and real-time scanning
 1. No (or minimal) extra bulk
 1. Can be uninstalled cleanly
 1. No connecting to Google Analytics or other similar operations

I am not concerned about CPU use during on-demand scanning.

This question is open to answers for any version(s) of Windows.  Compatibility with *every* version (such as XP) is not required.

Based on these simple requirements, the following do *not* qualify (based on current [AV-Comparatives][2] testing):
Avast, AVG, Trend Micro, Baidu, F-Secure, ThreatTrack Vipre, Fortinet, Panda, Quick Heal, Lavasoft, and BullGuard.
