What Avast Free Antivirus for Windows Is and How It Works

Avast Free Antivirus for Windows is endpoint security software designed to detect and block malware, including viruses, ransomware, and spyware, on consumer PCs. The Windows version focuses on always-on scans and cloud-backed detection engines Avast, 02/15/2024.
