Want to know more? You can dig in for a detailed description of how we test security software. Antivirus products distinguish themselves by going beyond the basics of on-demand scanning and real-time malware protection. Some rate URLs that you visit or that show up in search results, using a red-yellow-green color-coding system. Some actively block processes on your system from connecting with known malware-hosting URLs or with fraudulent phishing pages.

Software has flaws, and sometimes those flaws affect your security. Prudent users keep Windows and all programs patched, fixing those flaws as soon as possible. The vulnerability scan offered by some antivirus products can verify that all necessary patches are present, and even apply any that are missing. Spyware comes in many forms, from hidden programs that log your every keystroke to Trojans that masquerade as valid programs while mining your personal data.

Any antivirus should handle spyware, along with all other types of malware, but some include specialized components devoted to spyware protection.

Publisher's Description

You expect an antivirus to identify and eliminate bad programs, and to leave good programs alone. What about unknowns, programs it can't identify as good or bad? Behavior-based detection can, in theory, protect you against malware that's so new researchers have never encountered it. However, this isn't always an unmixed blessing. It's not uncommon for behavioral detection systems to flag many innocuous behaviors performed by legitimate programs.

Whitelisting is another approach to the problem of unknown programs. A whitelist-based security system only allows known good programs to run. Unknowns are banned. This mode doesn't suit all situations, but it can be useful. Sandboxing lets unknown programs run, but it isolates them from full access to your system, so they can't do permanent harm. These various added layers serve to enhance your protection against malware. Firewalls and spam filtering aren't common antivirus features, but some of our top products include them as bonus features.

In fact, some of these antivirus products are more feature-packed than certain products sold as security suites. Among the other bonus features you'll find are secure browsers for financial transactions, secure deletion of sensitive files, wiping traces of computer and browsing history, credit monitoring, virtual keyboard to foil keyloggers, cross-platform protection, and more. You'll even find products that enhance their automatic malware protection with the expertise of human security technicians.

And of course we've already mentioned sandboxing, vulnerability scanning, and application whitelisting. We're seeing more and more antivirus products adding modules specifically designed for ransomware protection.

Some work by preventing unauthorized changes to protected files. Others keep watch for suspicious behaviors that suggest malware. Some even aim to reverse the damage. Given the growth of this scourge, any added protection is beneficial. Your antivirus utility works in the background to keep out any faint possibility of infestation by malware, but its abilities don't extend beyond the bounds of your computer. When you connect to the wild and wooly internet, you risk the possibility that your data could be compromised in transit.

Sticking to HTTPS websites when possible can help, but for full protection of your data in transit you should install a virtual private network, or VPN. This component is important enough that we're starting to see it as a bonus feature in some antivirus tools. Which antivirus should you choose? You have a wealth of options.
