Malware, Spyware, and Adware Protection
Summer is winding down. Before you know it, kids will head off to school and come back with homework, notes from the teachers, and…malware? Quite possibly. You've protected your own PCs and laptops, but did you make sure to install antivirus protection on your child's laptop? If not, your kid could pick up more than a head cold at school. Viruses, Trojans, ransomware, or what-have-you, any kind of malware does well in a network populated by youths who aren't thinking about security. We've tested and rated more than 40 antivirus tools so you can pick the right one to protect you and your family from the evil side of the internet.

We call it antivirus, but in
Some nonstandard commercial antivirus utilities proved effective enough to earn an excellent four-star rating alongside their more traditional counterparts. VoodooSoft VoodooShield bases its protection on suppressing all unknown programs while the computer is in a vulnerable state, such as when it's connected to the internet, and also acts to detect known malware. The Kure resets the computer to a known safe state on every reboot, thereby eliminating any malware. If you have malware, one of the ten products in the chart above should take care of the problem.
You may notice that one product in the chart earned just 3.5 stars. The chart had room for one more, and of the seven 3.5-star products, the labs only pay attention to F-Secure and G Data. F-Secure has the added fillip of costing the same for three licenses as most products charge for just one, so it made its way into the chart. The blurbs at the bottom of this article include every commercial antivirus that earned 3.5 stars or better.
These commercial products offer protection beyond the antivirus built into Windows 10; the best free antivirus utilities also offer more. 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.
Listen to the Labs
We 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.
We follow four labs that regularly release detailed reports: SE Labs, AV-Test Institute, MRG-Effitas, and AV-Comparatives. We also note whether vendors have contracted with ICSA Labs and West Coast labs for certification. We've devised a system for aggregating their results to yield a rating from 0 to 10.
We Test Malware, Spyware, and Adware Defenses
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. Depending on how thoroughly the product prevents malware installation, it can earn up to 10 points for malware protection.
Our malware protection test necessarily uses the same set of samples for months. To check a product's handling of brand-new malware, we test each product using 100 extremely new malware-hosting URLs supplied by MRG-Effitas, noting what percentage of them
Some products earn absolutely 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 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.
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
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
Beyond Antivirus: VPN
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.
What's the Best Malware Protection?
Which antivirus should you choose? You have a wealth of options. Kaspersky Anti-Virus and Bitdefender Antivirus Plus routinely take perfect or near-perfect scores from the independent antivirus testing labs. 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 four 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 we have reviewed many more antivirus utilities than we could include in the chart of top products. If your favorite software isn't listed there, chances are we did review it. The blurbs below include every product that managed 3.5 stars or better. All the utilities listed in this feature are Windows antivirus apps. If you're a macOS user, don't despair, however; PCMag has a separate roundup dedicated solely to the best Mac antivirus software.
Editors' Note: We are aware of the allegations of Kaspersky Labs' inappropriate ties to the Russian government. Until we see some actual proof of these allegations, we will treat them as unproven, and continue to recommend Kaspersky's security products as long as their performance continues to merit our endorsement.

Even with anti-virus software installed, computers can still become victim to malware like Trojan horses; cybercriminals continue to develop infections that skirt around the protections security software provide. While Norton Antivirus can remove these infections, it's important for businesses to be aware of the application's deficiencies in malware detection and removal.
Description
The term 'Trojan horse' comes from the Greek tale of the Trojan War, in which the Greeks, as an act of subterfuge, presented to their enemies, the Trojans, a large wooden horse. A few Greek soldiers hid inside the structure. In the middle of the night, the soldiers emerged from the horse and opened the city gates, allowing the Greek forces to enter and take over Troy. Trojan viruses, as in the the narrative, seem benign but contain malicious content. Trojans are applications that appear to serve some useful function -- a number of these infections, for example, masquerade as anti-virus software -- but include code that performs operations without the user's permission or even enables an attacker to gain remote access to a PC.
Mcafee Antivirus
Function
Trojan horses are divided into different groups depending on their method of abuse, but the most common and most dangerous are remote-access Trojans. Once a hacker gains access to an infected system via a RAT, the individual can steal confidential information, install additional malware to the computer, record and log keystrokes, damage the integrity of the hard drive, and countless other activities that can cost a business thousands of dollars to resolve. Hackers also use RATs to deliver Trojans to other PCs and create botnets.
Resolution
Norton Antivirus detects and removes Trojan horses. Via LiveUpdate, administrators can download to a computer the latest virus definitions, which contain information that the scan engine needs to find existing and emerging threats on a system. After bringing Norton Antivirus up-to-date, admins should perform a virus scan in Safe Mode to search for Trojans and other viruses. The software allows users to quarantine, delete or restore the infected files it finds. The program can also repair files, but that's not an option for a Trojan horse, since the entire application contains malicious data.
Problems
Norton Antivirus, like all antivirus software, cannot detect all malware on the Web. If a workstation becomes victim to a Trojan horse, but Symantec has not rolled out a patch for the infection, not only will Norton Antivirus not remove the virus, but it typically won't even know that the infection exists. To workaround this shortcoming, educate employees on safe browsing; advise users to download files only from trusted websites. Norton Antivirus, in rare cases, may also report false positives. In other words, Norton Antivirus will label a benign program as malicious if it detects code that matches a string of character in a known virus. If you know the program is safe, you can report the false positive to Symantec (link in Resources).
