Malware, Spyware, and Adware Protection
How would you rather spend your summer vacation? Relaxing on the beach with your besties, or recreating all the chapters of your great American novel, because ransomware destroyed the originals? I know what I'd choose. The best way to ensure uninterrupted summertime chilling is to make sure that your computers are protected against ransomware and other malware attacks. How? By installing an antivirus utility. We've reviewed more than 40 current antivirus tools—one of them is sure to be right for you.
I did say 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. PCMag has reviewed more than 40 different commercial antivirus utilities, and that's not even counting the many free antivirus tools. Out of that extensive field we've named four Editors' Choice products.
Several other commercial antivirus utilities proved effective enough to earn an excellent four-star rating. I eliminated two special-purpose products that aren't really like the rest: Daily Safety Check Home Edition and VoodooSoft VoodooShield. And Check Point's ZoneAlarm PRO uses antivirus licensed from Kaspersky, with almost no lab test results for ZoneAlarm itself. That leaves the ten excellent products you see above.
All of these products are traditional, full-scale, antivirus tools, with the ability to scan files for malware on access, on demand, or on schedule. As for just relying on the antivirus built into Windows 8.x or Windows 10, that may not be the best idea. In the past, Windows Defender has performed poorly both in our tests and independent lab tests It did score several wins last year, and it earned decent scores in several more recent tests. Even so, our latest evaluation indicates that you'd still be better off with a third-party solution.
Listen to the Labs
I take the results reported by independent antivirus testing labs very seriously. The simple fact that a particular vendor's product shows up in the results is a vote of confidence, of sorts. It means the lab considered the product significant, and the vendor felt the cost of testing was worthwhile. Of course, getting good scores in the tests is also important.
I follow five labs that regularly release detailed reports: Virus Bulletin, Simon Edwards Labs (the successor to Dennis Technology Labs), AV-Test Institute, MRG-Effitas, and AV-Comparatives. I also note whether vendors have contracted with ICSA Labs and West Coast labs for certification. I've devised a system for aggregating their results to yield a rating from 0 to 10.
We Test Malware, Spyware, and Adware Defenses
I also subject every product to my own hands-on test of malware blocking, in part to get a feeling for how the product works. Depending on how thoroughly the product prevents malware installation, it can earn up to 10 points for malware blocking.
My malware-blocking test necessarily uses the same set of samples for months. To check a product's handling of brand-new malware, I test each product using 100 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 absolutely stellar ratings from the independent labs, yet don't fare as well in my hands-on tests. In such cases, I 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 Protection
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.
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, Ransomware Protection, and More
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 I've already mentioned sandboxing, vulnerability scanning, and application whitelisting.
I'm 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.
What's the Best Malware Protection?
Which antivirus should you choose? You have a wealth of options. Kaspersky Anti-Virus and Bitdefender Antivirus Plus invariably rate at the top in independent lab tests. Norton AntiVirus Basic aced both lab tests and my own hands-on tests. A single subscription for McAfee AntiVirus Plus lets you install protection on all of your Windows, Android, Mac OS, and iOS devices. And its unusual behavior-based detection technology means Webroot SecureAnywhere Antivirus is the tiniest antivirus around. We've named these five Editors' Choice for commercial antivirus, but they're not the only products worth consideration. Read the reviews of our top-rated products, and then make your own decision.
Note that I reviewed many more antivirus utilities than I could include in the chart of top products. If your favorite software isn't listed there, chances are I did review it. The blurbs below include every antivirus that earned at least three stars. You can also see all the relevant reviews on PCMag's antivirus software page.

Symantec Norton AntiVirus Basic Review
Editors' Choice
$39.99 MSRP

Webroot SecureAnywhere AntiVirus Review
Editors' Choice
$39.99 MSRP

McAfee AntiVirus Plus (2017) Review
Editors' Choice
$59.99 MSRP
Bottom Line: McAfee AntiVirus Plus doesn't score as high as other Editors' Choice products in testing, but it covers vastly more than the others. One subscription lets you protect every Windows, Android,...
Avast Pro Antivirus 2017 Review
$39.99 MSRP
Bottom Line: Avast Pro Antivirus 2017 offers the same wealth of features as its free edition, and not a lot more. It's an excellent product, but for most people the free version will suffice.
Check Point ZoneAlarm PRO Antivirus + Firewall 2017 Review
$39.95 MSRP
Bottom Line: With the powerful ZoneAlarm firewall, antivirus licensed from Kaspersky, and a unique new approach to phishing protection, Check Point ZoneAlarm PRO Antivirus + Firewall 2017 is worth a look...
Emsisoft Anti-Malware 2017 Review
$39.95 MSRP
Bottom Line: Hence the name, Emsisoft Anti-Malware focuses on the core task of keeping your PCs free of malware. It does a good job, and with a clean, simple interface, it looks good too.
ESET NOD32 Antivirus 10 Review
$39.99 MSRP
Bottom Line: ESET NOD32 Antivirus 10 scores well with most independent labs and in most of our hands-on tests, and its full system scan is faster than most.
F-Secure Anti-Virus (2017) Review
$39.99 MSRP
Bottom Line: F-Secure Anti-Virus's fast full scan and DeepGuard behavior-based detection system make it a powerhouse against malware, but it doesn't offer many bonus features.
The Kure Review
$19.99 MSRP
Bottom Line: When your PC has The Kure installed, you can wipe out malware just by rebooting. Your own documents aren't affected, and it even has the ability to reverse the effects of encrypting ransomwa...
Trend Micro Antivirus+ Security (2017) Review
$39.95 MSRP
Bottom Line: Trend Micro Antivirus+ Security earns high scores in our hands-on tests, though not in every independent lab test. Ransomware protection is a welcome addition in this latest version.
VoodooSoft VoodooShield Review
$19.99 MSRP
Bottom Line: VoodooShield takes a whitelist approach to antivirus protection, but without getting in the user's way. A new machine-learning component brings it closer to the abilities of a standalone ant...
Ashampoo Anti-Virus 2016 Review
$49.99 MSRP
Bottom Line: The technology that Ashampoo Anti-Virus licenses from other companies does very well in most of our tests, but you're probably better off just going straight to those other vendors.
G Data Antivirus 2017 Review
$39.95 MSRP
Bottom Line: G Data Antivirus 2017 gets decent marks from the independent testing labs, and it includes components designed to fight specific malware types, including ransomware. However, in our own test...
Malwarebytes 3.0 Premium Review
$39.99 MSRP

Avira Antivirus Pro (2017) Review
$44.99 MSRP
Bottom Line: Avira Antivirus Pro offers all the same protection as the free Avira Antivirus, plus a few added features that don't all work well. Stick with the free edition or, in a commercial setting, l...
BullGuard Antivirus (2017) Review
$29.95 MSRP
Bottom Line: BullGuard Antivirus offers spam filtering as a bonus feature, and it scored well in our malicious URL blocking test. However, in some independent lab tests and some of our own, it didn't do ...
K7 AntiVirus Plus 15 Review
$39.95 MSRP
Bottom Line: K7 Anti-Virus Plus 15 avoids the plague of false positives that afflicted the previous version. Its scores in our tests and lab tests have improved, but they're still not great. Better optio...
Panda Antivirus Pro (2017) Review
$39.99 MSRP
Bottom Line: Panda Antivirus Pro has all the features of Panda's free antivirus and more. It's a decent product, but its test scores are down from last year, and its pricing scheme doesn't make much sens...
PC Pitstop PC Matic Review
$50.00 MSRP
Bottom Line: PC Matic blocks execution of any program that isn't on its whitelist, which includes all types of malware. It has a great price per device, but you'll have to put up with it occasionally blo...
Quick Heal AntiVirus Pro 17 Review
$30.00 MSRP
Bottom Line: Quick Heal AntiVirus Pro 17 is a huge improvement over the limping version 16, though still not among the antivirus elite.
TotalAV Review
$19.00 MSRP
Bottom Line: TotalAV's collection of bonus features includes password management, system cleanup, and even a VPN. However, our tests show that its core antivirus capabilities need work.
