SafetyDetectives complains about the many background processes that Sophos requires to run. That said, it praises its ease of use.
Antivirus and firewall – ZoneAlarm promises all this with its free offering. The virus and malware detection capabilities of the antivirus solution are solid, plus it has convenient features such as wireless-network and identity protection. It also includes automatic real-time updates and a “do not disturb” mode. The firewall features a Full Stealth Mode that is designed to make you invisible to hackers. ZoneAlarm is available for PCs running Windows 7 or later (32-bit and 64-bit). Overall, this makes the security software one of the best free antivirus programs available.
What the experts say: Cloudwards gives the thumbs up to the firewall function and ease of installation. The thumbs down went to its virus detection capabilities. It’s also lacking in functions such as a password manager, anti-phishing protection, and a file shredder.
