Additional one: Malwarebytes free:

Although Malwarebytes Free is a popular antivirus tool, we are not able to include it in the list of top 5 free antivirus software for Windows. Because first of all, it doesn’t provide live virus protection. It works as a virus-removal tool. In fact, it is not an antivirus program, but rather a very useful malware-removal tool. On the other hand, its malware detection ability is a little bit weak than some of its rivals.

Malwarebytes Free review

Malwarebytes Free, which was formerly called Malwarebytes Anti-Malware does an excellent job of cleaning up malware already on your system as well as removing adware and potentially unwanted programs that could be causing problems. It is a minimal antivirus scanner with good virus detection and removal rates. So you can call it a countermeasure, not a live virus protection tool. To get real-time virus protection, you need to upgrade it to Malwarebyte Premium.

Malwarebytes Free is a great choice for users looking for a simple antivirus scanner that they can install and forget about. Its virus scanner uses a virus database as well as heuristics to catch all types of malware. It has anti-malware and anti-exploit protection which works very well.

In addition to the scanner, you also get a browser extension that blocks a host of threats including malware, phishing sites, ads, trackers, scams, and popups. One of the nice features of this extension is that all protections are turned on by default, so there’s nothing for you, but also lets you turn off one or all protections easily.
