The best antivirus of all

Unfortunately, the unlimited password manager has been discontinued. The program is also very customizable, letting you tweak its appearance and functions to suit your style. It even offers limited access to Avast's VPN service. However, Avast Free Antivirus caused a pretty heavy system load in our testing and its scans took a long time.

It also kept nagging us to upgrade to Avast's paid antivirus protection, and played bait-and-switch with features that looked like they were free but weren't. Most significant of all, the malware protection in Avast Free Antivirus is a peg down from Kaspersky's or Bitdefender's, whose free programs also bothered us less about paid upgrades and had lighter system loads.

Read our full Avast Free Antivirus review. AVG shares a decent, if unspectacular, malware-detection engine with its corporate sibling Avast while having a much lighter system-performance impact. While the latter is almost a free security suite with lots of bells and whistles, AVG AntiVirus Free is the quiet, neglected child that gets the hand-me-downs.

The good news is that AVG's wide range of customization options and its file shredder and system optimizer are still available, and its interface is open and easy to use. Worst of all, given its middling malware detection and dearth of extra features, there's no convincing reason to choose AVG AntiVirus Free over the built-in and overall better Microsoft Defender.

Malwarebytes Free, formerly called Malwarebytes Anti-Malware, is not antivirus software. Instead, it's a very useful malware-removal tool. What's the difference? Unlike antivirus software, Malwarebytes Free can't prevent a PC from being infected. But it does an excellent job of cleaning out malware that's already on your system, as well as removing legal adware and potentially unwanted programs that antivirus software often ignores.

Malwarebytes Free doesn't interfere with any antivirus software that's already installed, so it's perfectly safe to install it alongside one of our recommended brands. Just don't upgrade to the paid Malwarebytes Premium, true antivirus software that does poorly in lab tests and which will conflict with other AV programs. We recommend Malwarebytes Free as a complement to any of the best antivirus programs, free or paid.

If you have young children at home, then consider midrange antivirus products, most of which include parental controls. Do you want an all-encompassing security solution? Or are you a techie who understands and the risks of using the internet?

Then a low-priced basic program might be all you need. MORE: How to buy antivirus software. Once you've got your priorities figured out, then determine how many machines you'll need to protect. Most vendors offer single-device licenses for Windows PCs. But multi-device, multi-platform licenses for five, 10 or more computers and mobile devices are available in midrange and premium antivirus packages, covering Windows, macOS, Android, iOS and sometimes even Linux. Some vendors offer plans that cover an unlimited number of devices.

Gone are the days when you could walk into a store and pay a one-time fee for an antivirus product that came in a box off a shelf. All the vendors now sell their software licenses as yearly or multiyear subscriptions.

The upside is that you'll always get the latest software, which you can download and install straight from the internet. Many antivirus products are sold online for much less than their list prices. But each brand offers basic, midrange and premium configurations of features and pricing, with every step up adding more features. Think of autos at a dealership. You can get a base-model car that will get you from place to place just fine. For a few grand more, you can buy a car with satellite radio, but no heated side-view mirrors, alloy wheels or in-car Wi-Fi hotspot.

Or you can spend a lot more to get a loaded car with all the fixin's. Antivirus makers also hope you'll spring for extra options, whether you need them or not. The one thing you can't trade up to is a bigger engine: All the Windows antivirus products in a given brand's lineup will use the same malware-detection engine and provide the same level of essential protection.

The software will have essential malware protection and maybe a password manager or a two-way firewall. They generally add parental controls, some of which are very good, plus a few other features such as webcam protection. They often include multi-device licenses and antivirus software for Mac and Android devices. At the top are the premium "security suites," which toss in all the extra security tools an antivirus brand can offer, such as password managers, VPN client software, backup software, online storage and even identity-protection services.

The password managers are often quite good, but the online storage can be paltry and the VPN services often don't give you unlimited data. We've collected the best premium antivirus packages on this list of the best internet security suites. Our evaluations are based on each antivirus program's interface, performance, protection and extra features. Was the interface intuitive and user-friendly? How badly did malware scans slow performance? How well did the program detect and remove malware?

Does the program offer useful additional tools? Some of our newer performance tests were done on a Lenovo ThinkPad T with a 2. To assess a program's impact on system speed on both Windows and macOS, we used our own custom tests, which measure how long a CPU takes to match 20, names and addresses on an OpenOffice or Excel spreadsheet. The longer it took the laptop to finish either test, the heavier the performance impact.

Each lab subjects the major antivirus brands' products to stress tests involving thousands of pieces of malware, including hundreds of previously unseen samples. Kaspersky antivirus products have been banned from U. Because the company is Russian and antivirus software can peer deep into a PC, using Kaspersky software would create an unacceptable risk for persons and organizations involved in national security and critical infrastructure.

However, we still think Kaspersky software is perfectly safe for home users. We've seen no evidence to convince us otherwise. Kaspersky researchers are well respected throughout the antivirus industry, and the company has publicly exposed Russian cyberespionage campaigns as well as those from the United States and other countries around the world.

Antivirus AV software is designed to detect, block, and remove malicious software on a computer or network. AV software is an advised layer of any cybersecurity system, as it is often the first line of defense to protect the computer before the malicious software burrows too deep. It offers protection to a computer or network and helps prevent the virus or other malicious code from spreading to other devices.

Hackers don't just make money by selling your personal information; they can use that data to buy things fraudulently, compromise your credit score, drain your bank account, and generally wreak havoc on your and your business's financial life. Adding antivirus software to your computers is the least you can do to protect yourself. Windows continues to fight viruses designed to exploit vulnerabilities in the operating system, and until those vulnerabilities are patched, AV software is the first line of defense.

Windows 10 is the first version to include its own AV software built into the operating system. But if you want something that offers specific protections, the best option is to add a paid version that covers your needs. However, a long-standing misconception is that computers using Mac or Apple operating systems are immune to viruses and other malicious software attacks.

That was true two decades ago, but as Apple products became more popular, cybercriminals found value in designing viruses and malware for those systems. Also, increasing numbers of attacks can bypass the operating system and go directly for applications and web portals, putting every type of computer system at risk. Other things you should consider doing to protect yourself against hacks are installing anti-malware software, using a VPN, improving your password, and setting up two-factor authentication on your devices.

While there are free options, you get better protection and more features with a paid subscription. Paid versions offer features such as VPN, password management, and parental controls.

Free AV software has improved greatly over the years, and again, anyone using Windows 10 already has free AV software that works pretty well. If all you want is software that detects malicious software, blocks it from doing damage, and scans your system, then free is good. Paid versions, however, will offer protections on web browsing, protect identity, or offer VPN services, as well as password managers and parental control across multiple devices and operating systems.

These are more essential now, as more people are working remotely or using a single device for work and personal computing. Viruses are designed to replicate and spread, while malware is a catchall name for all types of malicious code aimed at damaging a computer or network.

All viruses are malware, but not all malware is a virus. AV software identifies threats through signature detections based on what is already known in the signature database. This is why AV software needs to be updated regularly. Antimalware software detects more sophisticated malware attacks. The two types of defense software complement each other, and some AV software has antimalware built-in, but the two are different, and protection against both is necessary for true protection. There are hundreds of antivirus software solutions available.

We investigated 20 popular solutions often considered the software of choice by cybersecurity experts. Of critical importance was the ease of use with all providers, making it something every consumer could navigate and use.
