These options provide reliable protection without slowing your computer significantly, installing unwanted add-ons, or harassing you about upgrades. This light, nonintrusive app works in tandem with built-in antivirus or by itself on macOS to provide greater coverage against bad stuff. Malwarebytes is not an all-in-one option for protecting your system against exploits, malware, and other bad stuff.

But information security experts repeatedly recommended it as a useful anti-malware layer, one of multiple layers of security you need for your devices, coupled with good habits. Relying on any one app to protect your system, data, and privacy is a bad bet, especially when almost every security app—including Malwarebytes and Windows Defender— has proven vulnerable on occasion.

The Best Antivirus App for Windows

You should have good virus and malware protection, yes, but you also need secure passwords, two-factor logins, data encryption, and smart privacy tools added to your browser. Check out our guide to setting up those layers here. As writers and editors for Wirecutter, we have combined decades of experience with different computers and mobile devices , and their inherent vulnerabilities. Then we interviewed experts, including computer-security journalists, experienced security researchers, and the information security team at The New York Times parent company of Wirecutter , whose responsibilities include but are not limited to protecting reporters and bureaus both overseas and here in the US from hacking and surveillance:.

So we tested Malwarebytes on Windows and macOS to learn how easy the app was to use, if it noticeably slowed performance or interfered with other apps, or if it had any annoying notifications.

7 Best Tips, Tricks and App to Clean Up Your Mac or PC

A quick terminology primer: The word malware just means "bad software" and encompasses anything that runs on your computer with unintended and usually harmful consequences. In contrast, antivirus is an out-of-date term that software makers still use because viruses, Trojan horses, and worms were huge, attention-getting threats in the s and early s. Technically, all viruses are a kind of malware, but not all malware is a virus.

Although each expert we interviewed had their own preferred solutions to the endless stream of computer threats, none recommended buying a traditional antivirus app. For many good reasons:. If you use Windows 10, you already have a robust antivirus and anti-malware app— Windows Defender —installed and enabled by default.

All the experts we spoke to recommended that most people stick to Defender as their antivirus app on Windows. Windows Defender does have the problem of being the default detection app that malware makers first attempt to work around. But having layers of security and good habits—especially sticking to official app stores and not downloading questionable free versions of things you should pay for, as we cover in another guide —should keep you safe from the worst kind of Defender-defeating malware.

AV-Test dinged Defender in usability in December due to false detections of legitimate software—it wrongly detected 16 out of 1. False detections, although annoying when too common, are preferable to a failure to catch something malicious. And although AV-Test gave Defender a demerit for slowing down the installation of some apps, the Microsoft app earned top marks and beat industry averages for launching websites, starting apps, and copying files, tasks you do far more often than installing apps.

The same trick is often used for fake utility apps like movie players or download managers.

Whether its spyware, viruses or trojans, there are tools available. So, let's take a look at a few of the best options available today that can help protect your Mac. Little Snitch isn't technically an antivirus or anti-malware app. It's a service that runs in the background as an interactive firewall.

    Antivirus software for your PC

    Any app that tries to communicate with another system, whether it's over the network or on the other side of the planet, has to go through Little Snitch. The first time an app tries to make a connection, Little Snitch pops up a request box, and you can choose to allow the connection or have it blocked.

    You also choose whether you want that choice to be temporary or permanent, and you can alter the "rules" you make at any time. Little Snitch also has a small status window that shows you exactly what's communicating with the outside world at all times, and it shows you where the data is being sent. Sophos is one of the most trusted authorities on malware and viruses in the industry, and their free offering for OS X is well worth the download if you're feeling insecure. It's extremely user-friendly and never tries to push you to "upgrade" to a paid version.

    It comes with its own uninstaller which is actually rare and it can scan networked drives which is even rarer. While you're using your Mac, it constantly scans in the background for viruses and known malware threats, along with any suspicious signs of unknown malware threats.

    It doesn't put a noticeable dent on your system's performance, and Sophos is extremely quick to react to emerging threats which means you'll always have up-to-date protection. Best of all, of course, is the fact that it's all free. ClamXav Clam Antivirus for OS X can look daunting to more inexperienced users, but it's actually pretty simple and very powerful for the tiny footprint it has. It puts nearly no drain on your system while running in the background, and you're able to pre-define what folders or drives are scanned in real-time. Whether you're running a system-wide scan, or just running ClamXav in the background, you can actually sit and watch the log file to see each and every file as its scanned.

    ClamXav is open source and free. Instead of running in the background, MacScan is meant to be run by the user, then closed when finished. It scans the system for all sorts of malware, but it differs from others by specifically targeting cookies. This isn't necessarily a bad thing, but it can get pretty annoying when your anti-malware scanner pops up with 27 alerts because of cookies picked up at major web sites.

    On the other hand, it can be very useful for users who want to rid their system of every last "tracking" cookie. The problem is that MacScan pushes very hard to get you to upgrade to the full version, and because of that, the free version is all but crippled. User control is a big selling point for the app, beginning with the installation options.
