Which Antivirus is Better?

Today’s antivirus software must be comprehensive and well-rounded in order to protect from all types of threats. Comodo and Zone Alarm are both highly-rated software who excel at malware protection. Their use of signature-scanning and behavior-monitoring ensures both known and known infections can be detected with accuracy.

Comodo is a simple security suite which offers airtight protection from viruses and other threats. Along with sophisticated detection protocols, it uses sandboxing technology to launch files in a secure virtual environment. Infections can be caught and quarantined without installing on your system. The Application Control locks down your device if you suspect an infection, but still opens trusted programs that are known to be safe. The Game Mode stops pop-ups from interrupting gameplay and other full-screen activities. Comodo offers a free tool for Windows, Mac, and Linux, although the full version costs up to $89.99.

Zone Alarm provides comprehensive security for all your needs. It uses sandboxing and crowdsourced insights as well as an advanced two-way firewall. It identifies hackers’ common tricks and includes an anti-phishing Chrome extension and anti-keylogger tool. The Wireless Network security will update your firewall based on the risk factor and users get 5GB of online backup storage space. Zone Alarm performs scans during the boot stages to spot infections before your system loads. The ‘Find My Laptop’ feature helps resolve physical theft of your device. Software package prices are similar to Comodo, but there’s no free version.
