User Feedback Microsoft Security Essentials in 2020

Microsoft Security Essentials v4.10.209.0, virus definitions v1.311.1278.0
4.00 star(s)
Installation Feedback
Installation is simple and requires only a few clicks. It asks us if we want to start a scan after virus definitions have been updated and to send "anonymous" threat samples. It also asks us if we want to enable Windows Firewall if it's not so.
Interface (UI)

Interface Feedback
The interface is the easiest one I've seen so far. You can't get lost, you have all settings in one single tab, it's perfect.

Usability Feedback
Overall, it's not bad. However, alerts come very often and can say the same thing. It's almost like spamming.
Scanning is slow but that's for a reason : it scans inside compressed/packed executable files and can scan a same file twice or even more!
Also, the tray icon is animated when you update the software, for example.
And finally, it needs only minimal interaction. You download it, you install it, you update it and you scan.
Performance and System Impact

Performance and System Impact Feedback
When it comes to performance and system impact, well, it's pretty bad. When IDLE, it doesn't consume that much resources. But when scanning or updating, that's another story. But it's still better than Malwarebytes.

Protection Feedback
Protection isn't that effective. For example, out of 1128 scanned elements (64 Rogue AVs, but it scans files twice etc.), it only detected 20 threats. And out of ~10K scanned elements (1K viruses), it only detected 232 of them. This is a poor/average score. We've seen way better.
  1. It's a free software
  2. Easy to use
  3. Simple and non-intrusive
  4. Virus signatures are updated very often
  5. Effective malware removal
  6. Well designed, clear interface
  1. Basics-only feature set
  2. Advanced users may want more control
  3. Short on configuration options
  4. Noticeable system impact
  5. Can be resource-hungry
  6. Antivirus capabilities are average at best
  7. Weak protection against zero-day threats
  8. Limited web protection
  9. Not as many features as some competitors
  10. Scans can be rather slow

agree with the most of review but cannot consider it a stand Alone AV anymore as it was dedicated for windows 7 environment which became non supported anymore (actually it became integrated in windows defender starting from windows 8 release and keep improving as it became great in windows 10 as AV test and our geeks here testing it and develop tools to make most out of it)
so to be fair the real one should be tested is windows defender not Microsoft essential as it suitable now for legacy OS (XP/windows 7 ) which also have better alternatives)

I personally wouldn't use it.
The main argument for using Defender is it's integrated into the OS but Security Essentials integrates the same as any other 3rd-party AV while lacking almost all of the features that other vendors offer for free.
