Sophos Free excelled in basic malware detection, stopping 98% of known threats in tests. However, it faltered on malicious URLs (only 57% block rate) and omitted essentials like a firewall or dedicated phishing tools. Its lightweight design (under 50MB install) caused just 5% CPU spikes, but the lack of updates post-discontinuation makes it risky.
