Useful Features to look for:

1. To simply start with, every antivirus product scans files on access to make sure malware can’t launch and also scans the entire system on demand, or on a schedule you set.

2. Blocking all access to malware-hosting URLs is a nice way to avoid trouble. Many products extend that protection to also steer users away from fraudulent websites, phishing sites that try to steal login credentials. A few rate links in search results, flagging any dangerous ones.

3. Behavior-based detection, a feature of some antivirus products, is a two-edged sword. On the one hand, it can detect malware that’s never been seen before. On the other hand, if it’s not done right, it can baffle the user with messages about perfectly legitimate programs.

4. Other useful bonus features include preventing USB-based malware attacks, scanning for router weaknesses, and cleaning up traces of browsing history.
