We call it antivirus, but in truth it's unlikely you'll get hit with an actual computer virus. Malware these days is about making money, and there's no easy way to cash in on spreading a virus. Ransomware and data-stealing Trojans are much more common, as are bots that let the bot-herder rent out your computer for nefarious purposes. Modern antivirus utilities handle Trojans, rootkits, spyware, adware, ransomware, and more.

These commercial products offer protection beyond the antivirus built into Windows 10 the best free antivirus utilities also offer more than Windows does. However, Microsoft Windows Defender Security Center is looking better and better lately, with some very good scores from independent testing labs. The combination of good lab scores and a great score in our hands-on malware protection test was enough to bring it up to 3.5 stars.
It doesn't appear in this roundup of commercial antivirus products, naturally. We take the results reported by independent antivirus testing labs very seriously. The simple fact that a company's product shows up in the results is a vote of confidence, of sorts. It means the lab considered the product significant, and the company felt the cost of testing was worthwhile. Of course, high scores in the tests are also important. We follow four labs that regularly release detailed reports: SE Labs, AV-Test Institute, MRG-Effitas, and AV-Comparatives. We Test Malware, Spyware, and Adware Defenses We've devised a system for aggregating their results to yield a rating from 0 to 10. We also subject every product to our own hands-on test of malware protection, in part to get a feeling for how the product works. Our malware protection test necessarily uses the same set of samples for months.ĭepending on how thoroughly the product prevents malware installation, it can earn up to 10 points for malware protection. To check a product's handling of brand-new malware, we test each product using a large collection of extremely new malware-hosting URLs supplied by MRG-Effitas, noting what percentage of them it blocked. Products get equal credit for preventing all access to the malicious URL and for wiping out the malware during download. Some products earn stellar ratings from the independent labs, yet don't fare as well in our hands-on tests. In such cases, we defer to the labs, as they bring significantly greater resources to their testing. Want to know more? You can dig in for a detailed description of how we test security software.
Multilayered Malware ProtectionĪntivirus 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.
