Avast Free Antivirus is the company's latest malware-hunting engine.
Installation is simple and straightforward. Compatibility seems good, too, with the package running happily alongside Bitdefender Internet Security on our test PC.
The program interface is clean and very easy to use. Just click "Run Smart Scan" and Free Antivirus immediately runs a quick check for malware, missing software updates, network vulnerabilities even looks for weak passwords and junk files.
When it's finished, clicking "Resolve all" allows you to review the results and fix whatever the program has found.
The previous Avast Free Antivirus extended the package with a new password manager. This generates strong passwords on demand, stores and fills them locally, and syncs them with free iOS and Android apps.
The network security scanner detects more router vulnerabilities and displays extra details.
WebShield has switched to a smarter and more compatible system of HTTPS scanning, as used in Firefox, Chrome and Opera.
The interface has been optimised and improved.
A solid antivirus engine with a good range of features, made even better by the new password manager.
