Best Antivirus for Windows
Bitdefender Antivirus Plus 2019 offers excellent protection for your home computer from a variety of malware types, including destructive ransomware, Trojans, rootkits and phishing schemes. In our tests of antivirus software, Bitdefender consistently blocked us from visiting malicious websites and stopped viruses from downloading. All threats are securely and completely deleted so no trace of them are left on your computer.
A gaming, or silent, mode is included in case you need more of your system’s resources for online gaming or watching videos, though we didn’t find Bitdefender to cause enough lag to be a problem while working and playing online. This software also includes a password manager and safe banking tools. Both functions help to protect your personal information, account numbers, user names and passwords as you enter them and work online. It is also one of only three antivirus programs we reviewed that include a VPN, so you can work online and not have your browser history traced, captured or logged. Bitdefender Antivirus Plus scans links and files shared on social media pages and lets you know if they are safe before you click or share them. It also scans your whole computer for any outdated software then gives you a legitimate link where you can safely download the latest patch or version.
Pros
  • Lets you delete threats safely
  • Includes a personal firewall
  • Masks bank account information
Cons
  • Requires extra steps to download and install
  • Parental control features cost extra
  • Doesn’t include a firewall

Best Free Antivirus
Avira Free Security Suite displays a large warning in your Chrome or Firefox web browser if you try to visit a site known to have malware on it. If a virus tries to automatically download to your computer, Avira stops it then moves the threat to the quarantine file.
This software comes with several security tools, like a system vulnerability scanner, a personal firewall and a VPN. Each tool is a separate module that you must set up individually, and you can’t access other tools without first returning to the beginning of the dashboard. Overall Avira does a decent job blocking malware, both malicious sites and virus downloads. Threats that make it to your computer are caught and quarantined by Avira Free Antivirus. The secure browsing feature marks search results so you can easily see which sites are safe to visit. Because Avira is a free program, it frequently displays pop-up ads. These caused some slowdown to our test computers. However, if you’re a gamer, Avira automatically enables its gaming mode that keeps the pop-ups at bay so you have more of your system’s resources and less interruption while you play.
Pros
  • No-cost virus protection
  • Software vulnerability scans
  • Includes parental controls
Cons
  • Frequent in-program ads
  • Causes your computer to slow down a bit
  • Password manager not included

Best Antivirus for Microsoft Edge
Despite not allowing third-party browser extensions, Trend Micro still blocks malicious websites and warns you about them in the Microsoft Edge browser, because even with Edge’s great security settings, some threats still sneak by. And Trend Micro stops infected files from downloading so there is no chance for the threat to sneak onto your computer.
Trend Micro scored a perfect 100 percent in our lab tests, one of the few programs that correctly recognized and blocked over 300 live malware samples. It also earned perfect detection scores in other independent laboratory tests. Trend Micro Antivirus + Security includes spam filters and USB scanning to keep threats from entering through email messages or removable drives. Other security tools, like safe banking or social media scanning, aren’t available with this version of Trend Micro, but are included, along with parental controls and a personal firewall, with Trend Micro’s Maximum Security software. Installing the program requires the same basic steps as most antivirus programs. You do need to enable the browser extensions in Mozilla Firefox and Google Chrome if you plan to access the internet with either of these browsers.
Pros
  • Earned a perfect score for malware detection
  • Blocks malicious sites and virus downloads in Edge browsers
  • Blocks spam email messages
Cons
  • Causes noticeable drag on your computer during scans
  • Doesn’t include a firewall
  • 24/7 telephone and expedited email support available only if you pay for it

Antivirus for Gamers
For online gamers who access sites and programs that tend to harbor malware, Avast is a good choice.
It is effective at blocking viruses and other threats, plus its gaming mode places the game sites you access on its white list the first time you visit the site. Each time you start a game, Avast suspends non-critical functions and doesn’t show pop-up messages so you’re not interrupted. This also lets you have more of your computer resources so you don’t experience any slowdown during your gameplay. Avast Free Antivirus has a handful of extra tools, like a vulnerability scan. But its paid version, Avast Pro Antivirus, includes a lot more and doesn’t have pop-up ads asking you to upgrade your malware program.
Pros
  • Automatic gaming mode
Cons
  • Has a lot of pop-up messages

Least Invasive Antivirus
VIPRE Advanced Security is the easiest program to install and use among the antivirus programs we tested.
It’s easy to find the tools, functions and folders you need because they are clearly marked with large icons and big text. Subfolders and tools, like the quarantine folder and custom scan settings, are in the main folders where you would expect them to be, so it’s not hard to navigate this program. Also, setting up VIPRE doesn’t take a lot of guesswork, and it doesn’t cause much slowdown of your computer while its running, even during deep virus scans. While third-party test laboratories don’t test VIPRE very often, we checked out how well it protects against malware and were happy to see it blocked 99 percent of the over-300 live malware samples we used for testing.
Pros
  • Doesn’t drag on your system
Cons
  • Doesn’t have a password manager

Why Trust Us?

We’ve been evaluating antivirus software for over 15 years. We test each program several times each year, both in our onsite testing facility, using a controlled network and live malware samples, and on our home computers, so we get a good idea of how antivirus programs work in a real-world scenario. We do quick evaluations when new security breaches are reported to ensure the programs we recommend will protect you from these new threats.

As part of our research, we talk to security experts that oversee the network protections at their place of employment, and we speak with professional hackers to understand both the hardware and software side of internet security. The Anti-Malware Testing Standard Organization (AMTSO) is a non-profit organization that sets standards for antimalware testing, and while we don’t subscribe as members, we do incorporate some of its standards in our testing methodology. For example, we either purchase or download the trial versions of each program for testing, and we never speak to antivirus companies during the testing period. This ensures we have a neutral testing environment.


We subscribe to IT and security news outlets and blogs, plus attend trade shows and conventions specific to internet security to stay aware of security breaches and changes in the industry. We follow local and congressional hearings on cybersecurity, so we have a good understanding of the international stage, its workings and issues that affect both government and personal computer security.

How We Tested

Over a five-month period, we downloaded and tested 14 antivirus programs on test machines running Windows 10, to determine the best overall and how each one individually performs while protecting a computer or laptop. We attempted to access malicious websites and phishing schemes, plus download some of the nastiest viruses, ransomware, Trojans and rootkits, through several internet browsers, since this is where the majority of threats come in and infect your computer. In all, we exposed each program to 352 live malware threats and noted how well each program recognized and blocked these threats. We gave higher scores to those programs that stopped threats before they could sneak onto our computers versus those that found and quarantined threats after they were let loose.

We tested each program using live malware a minimum of 12 times and used all three of the most popular web browsers – Microsoft EdgeGoogle Chrome and Mozilla Firefox – to learn how well the antivirus programs work alongside them. We performed tests with the browser’s own security features turned on, and then disabled them so we could see if the antivirus software could detect threats not caught by the browser, or if there was any dependency on the browser’s security feature for the antivirus software to work more effectively. Our final malware detecting and blocking score is a combination of our findings and test results from several other independent laboratories that also test internet security software, including AV-Test and AV-Comparatives.

On top of testing how well each program protects your computer, we also evaluated how easy each program is to download, install, set up and use. The Congressional Internet Caucus, a 100-member group of bipartisan U.S. senators and representatives, teamed up with the Senate Cybersecurity Caucus to hold a Congressional Cybersecurity Hearing in May 2018. Cybersecurity experts from L0pht addressed the group about the current internet safety precautions in place and what more can be done to keep everyone safe from cyber attacks. One L0pht member, Joe Grand, told the Caucus that people don’t use internet security solutions that are too complicated. We agree! This is why our Ease of Use score is important in helping you determine which programs don’t require a lot of extra steps.

Most antivirus programs require some setup to work properly, and the majority of them need you to turn on the safety tools inside your browsers before it can detect and block malware coming in through the internet. We gave an average score of 85 percent to these programs then added, or took away points depending on consolidated processes, added steps, ease of navigation, etc. For example, VIPRE has you enable its browser extensions function from the user dashboard. With one click VIPRE monitors every browser, cutting down on the steps you need to take (and the complex navigation of browser settings) to stay protected. We felt this was a great tool that makes VIPRE easier to use than other programs, so we bumped up its Ease of Use score.

And finally, we looked at how much of our computers’ resources were used by each program. Most programs create a little delay, but the best antivirus products don’t create enough to be noticeable while you’re working online. To test the effect on our systems, we first performed basic tasks while no antivirus programs were installed. We then performed the same tasks, navigating the web, downloading files and programs, attaching file and images to outgoing email messages, watching videos and playing online games, while the antivirus programs performed deep virus scans. We compared the recorded time of all the tests to see how much of a delay each antivirus program created. In some cases the lag was very noticeable. For others the delays were just fractions of a second.


While we only ranked the top 10 antivirus programs, we still reviewed the other four programs we tested. You can still read the results of our testing and our overall thoughts for Panda Dome Essential, eScan Anti-Virus, F-Secure Anti-Virus and AVG Antivirus FREE here.

FAQs

Here are a few commonly asked questions and what you need to know before buying an antivirus program for your Windows computer.

How much does good antivirus software cost?
Basic antivirus software generally costs between $30 and $50 each year to protect a single computer. These programs don’t have a lot of extra security features but will offer discounts if you need to purchase multiple user licenses.

More inclusive security suites are available for around $80. These typically come with three or more user licenses and include additional protection features like password managers, safe banking features, VPNs and mobile security

What is the cheapest antivirus software?
This depends on the current sales promotion. However, both Bitdefender Antivirus Plus 2019 and Kaspersky Anti-Virus 2019 retail their lowest package for $59.99, which comes out to just under $20 for each of the three user licenses included with these packages. If you only need a single license, Webroot is the cheapest at $29.99 compared to most other programs that start at $50 to protect one computer. There are some companies, such as AVG and Avira, that offer free antivirus programs with fewer features.

What is the best free antivirus?
Avira is the best free antivirus program we tested because it comes with so many tools that other programs, even paid antivirus programs, don’t typically come with. These include parental controls, vulnerability detection, automatic gaming mode and a VPN. And don’t discount Avast and AVG, which also come with password managers and vulnerability scanners. Other companies that offer a free antivirus solution include Norton, Bitdefender and Panda, but they are pretty bare-boned compared to Avira, Avast and AVG.

The biggest drawback of free antivirus programs, besides the lack of security tools, is the number of pop-up ads asking you to upgrade to the paid version. The protection is the same for free antivirus as it is for the pricier internet security programs offered by the same company, but the paid programs do come with more tools, like a personal firewall, vulnerability detection and password managers.

Is Bitdefender safe?
In 2017, the U.S. government accused Kaspersky of partnering with the Russian government to gather information and spy on departments and officials. The U.S. government banned the use of Kaspersky’s security programs for both agencies and workers’ personal computers that would be used for work. Accusers believe that Kaspersky used its data sharing tools to gather sensitive information virtually undetected. Kaspersky has adamantly denied these accusations and recently has begun moving several of its primary operations out of Russia as a way to prove its innocence and build good faith with its users. Because of the uneasiness surrounding this company, consumers have become wary of using other antivirus programs and their data sharing tools.

Bitdefender Antivirus Plus 2019 also has a data sharing program that allows the software to send information about viruses, Trojans, rootkits and other malware found on your computer back to its databases. This is a way to keep tabs on new threats and pass along protection to other Bitdefender users before the malware becomes a cyber outbreak. There hasn’t been any evidence of Bitdefender gathering inappropriate or unauthorized information, so we’re confident Bitdefender is safe to use. However, you can turn off this feature altogether from the Bitdefender dashboard if it worries you.

What is the best antivirus software for Mac?
We tested 14 Mac antivirus programs with 165 live malware samples. After several months of repeating our malware protection tests, we learned that Bitdefender Antivirus for Mac is a good program that blocks 99 percent of malware threats, warns you of dangerous websites before you visit them and comes with a minimum of three user licenses, which makes it a good overall value. We also highly recommend Norton Security Standard that did slightly better in our detection and protection tests and is a bit easier to use than Bitdefender, but it does cost more. Also, Intego Mac Security X9 is a good antivirus program specifically designed for Mac computers.

What is the best mobile security antivirus software?
Your smartphone should come with a standard antivirus program preinstalled, such as Lookout on Android devices. These programs, if you keep them updated, are usually sufficient to keep viruses off your phone. Basic antivirus programs typically aren’t compatible with mobile devices, but you can get more comprehensive mobile protection for your Android or iOS cellphone when you purchase a premium internet security program or computer protection software.


Programs such as Kaspersky Internet Security, Norton Security Premium and Trend Micro Maximum Security include Android and iPhone compatible protections and additional security tools that that make mobile devices a little more secure. These include password managers, antiphishing functions and spam filters.

Protect Your Identity While Shopping Online


According to Statistia, Cyber Monday in 2016 brought in close to $2.67 billion of revenue from online shopping, and experts predict an even larger percent of purchases will be made online this holiday season. Most online retailers use security protections to help keep their customers safe, but there are a few things you can do to protect your personal information from identity thieves, hackers and other internet snoops.

Don’t follow email links
The biggest risk to online security comes through phishing schemes. These are generally sent through email and look like legitimate offers from your favorite retailers promising a percentage off your purchase or early bird specials with a direct link from the message to the retailer’s website. However, phishing schemes gather your full name, credit card number and address then turn around and sell it on the black market or charge your card over and over and over again.

One way to ensure an offer is real is to type the retailer’s webpage URL directly into your browser’s address bar. You can still enter promo codes or take advantage of deals from the site directly if the message was from the retailer.

Don’t autosave credit card information

Most retailers offer to save your credit card information on their website so you don’t have to reenter it the next time you shop through their online store. While this is a convenient way to avoid having to pull out your card for each purchase, it also puts you at risk of having your information swiped. Even retailers that use extra secure SSL encryption are not 100 percent safe from a data breach. It is best to not save your personal information online, but take the time to enter it for each transaction.

Don’t use the same password for all accounts
Just about every online retailer asks you to create an account before checking out, and with lots of great stores to shop from, it may be tempting to use the same username and password for all of them. Don’t! If a keylogger, hacker or internet snoop is able to capture your password, they can gain access to all of your online accounts, including bank accounts, email and social media.

Create complicated passwords
In an email to Top Ten Reviews, Mitch Stephens, a security consultant with Emagined Security, recommends creating unique passwords for each account that are hard to figure out and don’t use personal information like your last name, birthdate or a pet’s name. This is because using this information makes it easier for hackers to guess your passwords. Stephens suggests using passwords that are at least eight characters long and use “uppercase, lowercase, numbers [and] special characters.”

If you have difficulty creating or remembering passwords, especially long complicated ones, look for an antivirus program, like Bitdefender, that includes a password manager. These tools secure your password in a specially designed bank that signs into your online accounts using the correct credentials while hiding them from identity thieves.
