Best Antivirus Software for Windows 10 Windows Central 2020

Windows Defender is pretty good at stopping a lot of threats from infecting your computer, but in both our own and other third-party lab tests, results show it isn’t foolproof. I strongly recommend installing an extra pair of eyes to help stop malicious downloads before they get the chance to attack your system. The best antivirus program for Windows computers is Bitdefender Antivirus Plus. Bitdefender doesn’t use a lot of resources, stops most malicious files before they download, and includes a few extra security tools, including a VPN.

Bitdefender Antivirus Plus provides fantastic protection against system-crippling viruses and other annoying malware, and for the price, it’s the best option. It includes several advanced protection tools that basic antivirus programs typically don’t have, including a VPN, safe banking tools, and a password manager.

During my tests, Bitdefender consistently stopped threats before they had a chance to start the download process, including ransomware, Trojans, and rootkits. When we attempted to visit a website that harbored malicious links and files, Bitdefender usually blocked them and displayed a warning message about what was lurking there. It did an excellent job of blocking phishing schemes, including those designed to look like social media and banking login pages. There were a couple of threats Bitdefender wasn’t sure were completely dangerous, but instead of letting them go free, the files were placed in the quarantine folder. This folder allowed me to look at them first before allowing Bitdefender to take care of them. When Bitdefender stops a threat, it scrubs your system to make sure it is clean. It then permanently removes the malware in a way that it can’t escape and re-infect your computer.

Virus and system scans take a bit longer than other antivirus solutions. Most antivirus programs take about five minutes to perform a quick scan and 20 for deep scans. Bitdefender took twice as long. However, Bitdefender doesn’t use a lot of system resources, so you can still work and play online without noticing any slowdown. I was able to upload and download files, send email messages, watch videos, and play online games while Bitdefender scanned my computers.


  • Real-time protection
  • Automatic malware scrubbing
  • Extra protection tools


  • Takes time to scan
  • No firewall

Best Premium Pick: Norton 360 with LifeLock

Norton 360 offers some of the best malware protection around and coupled with LifeLock, you get identity theft protection, too. During my tests, I found it easily identified and stopped malicious files during the download phase. When I attempted to access phishing schemes, Norton blocked me from them, including several made to look like login pages from popular sites like Facebook and PayPal. I’ve checked out LifeLock over the years, too, and know it works hard to keep your personal information private and to ensure your identity isn’t being sold on the black market, used for insurance or medical fraud, or been used to clone social media and other online accounts.

With safe browsing tools, Norton tags malicious sites in search results so you can avoid visiting a sketchy one and possibly inadvertently infecting your computer with a virus. Norton also includes a VPN that hides your online identity and computer IP address to make it harder for adware, trackers, and cookies to follow your online movements. This antivirus program also has special banking protections that ensure when you’re logging into a real site that your passwords are masked and financial information is protected from being swiped. My biggest complaint is that when Norton was installed on my home computers and mobile devices, the slowdown was very apparent and very frustrating.

To help protect younger members of your family, Norton 360 has parental controls that both block inappropriate content and let you set time limits of when and how long children can be online. It also has webcam protection that monitors your computer’s camera and ensures programs or people can’t access it without your permission.

All of these features cost over $100, which is a lot more than most basic antivirus programs. However, on top of excellent protection and extra security features, you also get a user license that works on unlimited devices. This means you can protect home computers — both Windows and Mac machines — and mobile devices, too. When you figure in this versatility, the overall cost per device tends to come in much, much lower than a single device license from any other antivirus solution.


  • Unlimited device protection
  • Stops phishing schemes
  • Identity theft monitoring
  • Best for people with multiple devices


  • Slowdowns are apparent
  • Expensive

Basic Antivirus: VIPRE Advanced Security

If you don’t want to mess with all the extra features and tools that come with a lot of antivirus solutions, then I suggest looking into VIPRE. VIPRE Advanced Security is simple antivirus protection, although it does come with a firewall, the number one antivirus tool besides malware blocking that I suggest having. VIPRE’s firewall looks at your internet connection and the messages going out from and coming into your device to ensure they are safe and not making your system or personal information vulnerable to threats.

VIPRE monitors email messages and blocks links or downloads sent in them. If you are sent suspicious messages, like a phishing scheme, VIPRE sends a copy of the message to its quarantine folder. Here you can open and read messages in a secure space without worrying about anything dangerous being let out.

Unfortunately, there’s a bit of a learning curve to using VIPRE. Though the dashboard is uncluttered, it takes a moment to learn that there are additional tools beyond the few located on the dashboard landing page. However, everything you need is on the dashboard, including enabling safe browsing. This is much simpler than trying to install and enable a browser extension, the method used by many antivirus programs. Even without a browser extension, VIPRE is good at stopping malicious files during the download process and keeping them from infecting your computer.


  • Includes a firewall
  • Quarantines email messages
  • Does drag on computers


  • Bit of a learning curve
  • Lacks extra features

Advanced Security: Avast Premium Security

Avast Premium comes with advanced security tools not typically included with basic antivirus programs, like secure banking tools to keep personal and financial information, a personal firewall to monitor your internet connection, and webcam monitoring to ensure complete privacy in your home. Avast also includes a password manager, system optimization scanner, and a VPN. All Avast programs include its free web browser that looks, feels, and works similarly to Google Chrome. The one feature missing that would make Avast Premium the ultimate security program is parental controls to keep a closer eye on kids while they are online.

I have Avast Premium Security on more personal devices than any other antivirus program, especially the computers my children use for gaming. This is because, on top of near-perfect malware protection, Avast has an impressive gamer mode. This function recognizes when you tap into gaming websites, like Steam and Origins, and automatically places them on its list of approved sites. While it still keeps malicious files at bay, it also reduces the number of resources being used and doesn’t interrupt your gameplay with annoying notifications or popups. And it holds off on performing scheduled scans until after you’re done playing. This is all to give you the best online gaming experience without any slowdown or interruptions. If you visit a gaming app that Avast doesn’t recognize, you can add it to the gaming list and Avast will automatically apply all the same gaming standards from that point on.

Avast Premium Security costs more than many antivirus programs because of the number of tools it includes. For new users, you can get 10 user licenses to protect multiple devices for under $100. Avast works on both Windows and Mac machines and Android and iOS cell phones. Another important note on Avast is that recently it was discovered that Avast sells user information to other companies including Google and Home Depot. You can opt-out of this, however, during the setup of Avast or under settings on its dashboard.


  • Excellent malware protection
  • Automatic gamer mode
  • Webcam monitoring
  • Tons of extra features
  • Works across devices


  • Expensive
  • Collects and sells user information
  • No parental controls

Best Free Protection: AVG Free AntiVirus

AVG’s free antivirus program is one of the easiest to install and use. Its dashboard uses icons for each function with those available colored green and those not ready in red. It does have a lot more features listed on its dashboard than are available with the free program. If you decide to upgrade to a paid subscription, these icons will turn green, too.

One of the best features of AVG is that is works in tandem with other antivirus programs, including Windows Defender. Other programs, during the install process, will notify you of other antivirus programs installed and require you to uninstall them before using their program. AVG lets you use both. It automatically recognizes when your other program is running in the primary position and will take a back seat. With its excellent protection ability, it will snatch up any threats your first security program misses. AVG does a great job of blocking phishing schemes, too.

During testing, I did notice that AVG does have some lag issues. It was most noticeable when I first opened a browser, or while waiting for a video to download or a page to fully load. Once the initial startup was done for any of these functions, I didn’t have any issues. Of course, since this is a free antivirus program, you will notice some ads enticing you to upgrade to AVG’s paid antivirus program. This does add to the slowdown issue a bit, but more often it’s simply just annoying.


  • Free protection
  • Works along with other programs
  • Good protection
  • Upgradable


  • Lots of ads
  • Some slow down

Family Solution: McAfee Total Security

For families, I highly recommend McAfee Total Protection. This antivirus program is chock-full of security features that monitor all your online activities without becoming too intrusive. For example, it has parental controls that let you set time limits and internet filters for when your children are online, and it has safe browsing features to stop malicious files from downloading, including gaming sites that sometimes have hidden dangers. It also includes home network monitoring, also known as a firewall, to keep an eye on all communication come and leaving your computer through your internet connections.

McAfee is compatible with multiple devices, including Android and iOS phones, so it doesn’t matter what devices your family uses — they can all be protected. If you enroll in McAfee’s autorenewal program, you also have access to its ID theft protection. This keeps tabs on your personal information and scours the dark web to ensure it isn’t being used maliciously or illegally.

In my tests, most of the over 100 samples used were recognized and quickly stopped by the software before the threats had a chance to fully download. Other test labs found similar results. Overall, McAfee earned an average protection score of 95%. Since the median score for all antivirus solutions is around 92%, this means McAfee protects better than average. I also looked at McAfee’s performance, and while I didn’t experience a lot of slowdowns when running McAfee on either lab test computers or while installed on personal home computers, it did create a little lag on some mobile devices.


  • Includes parental controls
  • Has a firewall
  • ID theft protection
  • Compatible across devices
  • A lot of security features for families


  • Slow down on some devices
  • A bit pricy

Resource-Friendly: Kaspersky Anti-Virus

Kaspersky Anti-Virus easily makes it to the top of my list because of its ease of use and the number of resources it uses to provide almost near perfect protection. Kaspersky, in my many years of testing antivirus programs, has consistently stopped most threats before files have a chance to download completely. This means, using real-time protection, Kaspersky doesn’t give malware a chance to come close to infecting your computer. Plus, it was one of the few programs that stopped me from accessing every phishing scheme I used during testing. Some of these threats were made to look like legitimate login pages for Facebook, PayPal, Instagram, and Twitter, so I feel very confident in recommending Kaspersky AntiVirus for home use.

This basic antivirus program also includes webcam monitoring, along with safe browsing tools that both tag and block malicious websites from being accessed and ensure banking and shopping accounts are accessed from a legitimate website. To give you even more security, all of Kaspersky’s antivirus programs include an in-browser keyboard. This lets you enter usernames and passwords, or other sensitive information, into text fields without worrying that a keylogger with capture it.

Kaspersky has gotten a pretty bad wrap because of the accusations made a few years back about possible filtering of information, gathered from Kaspersky users’ computers, to the Russian government, As a precaution, the U.S. banned the use of Kaspersky programs from being used on any of its departments’ computers. But for most users, Kaspersky is just fine to use.


  • Uses minimal resources
  • Real-time protection
  • Virtual keyboard


  • Not recommended for government workers

Protection without slowdown

Kaspersky features great malware protection without using a lot of system resources or causing slowdown on your computer.

Banking Protection: Trend Micro Antivirus+ Security

Trend Micro is impressively good at stopping malware threats. In our tests, Trend Micro successfully prevented every single one of the hundreds of malware samples used. It didn’t wait until after the file was downloaded entirely before snatching the threat, either. Trend Micro also prevented us from accessing phishing schemes and other dangerous websites known to harbor malicious links by displaying a warning message with some information about what was being stopped. This is done by using web reputation technology that looks for signs of a fake site and quickly marks it as dangerous.

Most importantly, this antivirus program includes Pay Guard, a tool specifically designed to shield your online banking and shopping transactions, so personal, account, financial and other sensitive information isn’t tracked or stolen. Pay Guard lets you store credit card numbers and bank accounts, so you don’t have to pull out your credit card every time you shop online — much like how a password manager stores passwords so you don’t have to remember them. However, Pay Guard has a lot more protections to keep your information more secure from being stolen.

As impressed as I am of Trend Micro Antivirus+ Security, it did create a noticeable slowdown on both lab and personal computers while installed and created a lot of lag while running virus scans. It was frustrating trying to download or upload files or even navigate the web because my mouse couldn’t keep up with my movements. In between scans, the lag wasn’t as bad, but it did take websites longer to load and apps more time to open.


  • Perfect protection score
  • Web reputation technology
  • Pay Guard


  • Creates noticeable lag
  • Difficult to set up

Here’s why Bitdefender dominates

Over the five years I’ve been testing antivirus programs, Bitdefender has held the top spot most of the time. This year is no exception. Bitdefender Antivirus Plus 2020 has all the great features you need to secure your computer from some of the nastiest threats including ransomware, Trojans, worms, and rootkits. It did an excellent job of recognizing phishing schemes designed to look like login pages of popular websites like Facebook and PayPal.

I love that Bitdefender stops infected files before the download process even begins and scrubs the threats clean from your computer immediately. If Bitdefender does come across a new threat or a suspicious file it doesn’t recognize, it places it in quarantine for a few days before permanently removing it.

The only real downside is how long it takes to scan your computer for viruses. Where other programs take under five minutes, Bitdefender easily takes five times longer. I do appreciate that Bitdefender is so thorough, and I like that it doesn’t take up too many resources so I can keep working or playing online during these scans and not worry about being disrupted by any slowdown.

Antivirus programs and data sharing

screenshot data collection

Source: Nicole Johnston/ Trend Micro

There has been a lot of news about antivirus companies using its software to collect user information. Recently, Avast has acknowledged it collects user information, such as search results and online browser histories, and sells it to third parties, such as Google. Every antivirus solution collects and uses customer data in some form or another. It’s safe to say every online interaction, program you use, and website you visit is logged some way, somewhere.

The first reason for antivirus programs to collect user data is to ensure updated malware information is logged in threat databases quickly. Zero-day threats, which are malware files so new they haven’t had a chance to be named, yet, are the most common threats picked up on user computers then shared with these databases. Without this information, too many systems would be vulnerable to malware attacks because it would take too long for antivirus programs to figure out these threats and how to stop them on each computer. Getting this information to shared databases quickly is the best way to protect everyone.

The second reason for collecting user information is for product research. It’s helpful for many software companies to know how their clients interact with the world wide web. Security software, especially, gathers information to better create programs that recognize spam messages, phishing schemes, and websites that tend to harbor malicious files. It’s also helpful to know information, such as how often users download videos and games, or shop and bank online, to better design and optimized protection tools for these activities.

The third reason for user data is to make money. It isn’t a secret that websites and software gather information about its users and send it along to business partners. These partners then use this information to created targeted ads. This is why after searching for a blender on Amazon you are then inundated with blender ads on Facebook.

It might make you uneasy to think about your information being gathered and shared, however, each antivirus program does give you the chance to opt-out of its data collection program. Every software I tested asked me during the initial download and setup if I wanted to participate in its collection program. In each instance, I opted out, though I could change my mind and opt back in simply by adjusting the appropriate settings. However, even when opting out of these programs, there is still going to be some information gathered. It is the only way software programs can better serve its users.
