Do you really need antivirus for Windows 11?

While built-in Microsoft Defender does its best to safeguard you, it’s not enough even when paired with the most secure browsers. If you work with sensitive data or just want more advanced security, you should look for an additional antivirus solution. A stand-alone antivirus software offers an all-around protection and greatly enhances your online experience thanks to extras like a VPN or password manager.

The main reasons for investing in a Windows 11 antivirus include these:

• Actively shields you from malware. Hackers are still eager to take advantage of ‘loopholes’ in Windows 11. For this reason, this OS is more susceptible to malware and other kinds of online or device-based threats.
• Prevents scammers from reaching you. Modern antivirus software ardently combats scamming attempts by implementing anti-phishing, ransomware, and spyware protection. Additionally, it employs wide-scale filtering to detect suspicious websites, emails, and other possible threat vectors.
• Helps create a safe online environment. An antivirus helps create a safer browsing experience. Also, most of them offer parental control to create safe online space for little ones.

Norton is one of the top antivirus for Windows 11 with impressive malware detection and real-time protection capabilities. It works seamlessly in the background, allowing you to enjoy safe and well-protected internet browsing.

The installation process and the app’s interface are very intuitive. Norton offers 4 different virus scanning types: quick scan, smart scan, custom scan & full-system scan. You also get a special scan – Norton Insight – that evaluates the trustworthiness of files and apps stored on your PC based on a database of known safe files. A quick scan took me around 30-40 seconds, while the full scan lasted for 12 minutes. It successfully scored around 98% at detecting viruses and malware. The software effectively combated ransomware, malware, malvertising, spyware, potentially unwanted applications, and more.

Additionally, your security is further cemented with the smart firewall, which monitors the network traffic, both incoming and outgoing. As for extra features, any of Norton 360 plans get you quite a list: a VPN, password manager, ad blocker, system optimization, PC cloud backup, parental control, SafeCam, and it’s not even all.

3. Bitdefender – intuitive & all-around Windows 11 antivirus

Bitdefender Antivirus Plus is among the top-tier Windows 11 antivirus, boasting well-rounded functionality and protection against online and device-based threats. Not only is it feature-rich and affordable, but it also has one of the best free versions in the market.

During my tests, this antivirus had a success rate of 98% against malware, ransomware, and other threat vectors. It has four types of scans: quick, system, vulnerability, and custom. The quick scan is a bit longer than competitors, taking less than 4 minutes, while the system scan takes around an hour. Surprisingly, the system scan didn’t slow down my computer. Besides, it uses very little RAM, even during most intensive scans. Also, its versatile features fall under three categories: Protection, Security, and Utilities. Thus, users get flexibility for their security.

I found out that Bitdefender does a splendid job protecting against viruses, worms, Trojans ransomware, spyware, and other cyber threats in real time. It also offers Online Threat Protection feature that scans your web traffic for malicious content. It perfectly works with not only Windows devices, but with iOS as well. Bitdefender also supports up to up to 5 devices at the same time.

Of course, you get a highly valued Password manager, Antispam, Identity Theft Protection, and other measures that add to the all-encompassing protection. However, I found it a little unfortunate that you need to pay extra to unlock the full functionality of the in-built VPN.

The cheapest plan you can get is Bitdefender’s Antivirus Plus, which costs the standard $0.83/month. However, you can check out this antivirus's many plans.

Surfshark antivirus is among the best multi-device solutions if you seek balance between robust shield from cyber threats and a clean Windows app. Though this brand is typically associated with the one of the top VPNs in the market, its quest for a safer cyber tomorrow has branched out into a package known as Surfshark One. When it comes to the antivirus, I was pleased with the solid 90% rate of dealing with malware online and offline.

I tested Surfshark AV’s protective capabilities with 10 malicious files, and it did find 9 of them. With a sleek and simple interface, the antivirus offers quick and full scans. Personally, I found the quick scan a bit too fast, as not so many files were scanned. The full scan took around 25 minutes, also a bit quicker than competitors' times. You can also schedule those scans, so you don’t have to remember to run them yourself.

Surfshark AV offers a bunch of extras. Security features like Webcam protection actively safeguard your sensitive data as some websites connect to your camera even if it’s disabled. It even includes a Private Search Engine to protect your online browsing from data tracking.

Avira antivirus is a great option for those seeking to protect their sensitive data and computers from ransomware and other cyber attacks. Besides strong protection, users can enjoy additional features such as a VPN, a password manager, browser extensions, and a file shredder.

I performed several tests to check whether Avira can compete with other antivirus softwares. The results showed a 70% success rate against 10 malicious files. While this score is imperfect, independent antivirus lab test results showed much better outcomes. In AV-Test, Avira earned 6/6 points in every category, and in AV-Comparatives, it was rated as Advanced+ antivirus.

The download and installation process of Avira antivirus was very smooth, taking around 4-5 minutes. The app is very intuitive, everything you need is included in four main tabs. You won’t waste time looking around since many necessary features are just one click away.

Talking about features, Avira has a vast selection of them. From basic needs like different scan options (full, quick, and smart), real-time protection, firewall to VPN, password manager, browser extensions, and file shredder.

Best antivirus software for Windows 11 compared

How I selected and tested Windows 11 antivirus tools

I’ve conducted comprehensive testing to ensure that my selected best antivirus for Windows 11 is truly worth it. The testing included CPU performance during scans, real-time protection reliability, firewall effectiveness, VPN functionality, and more.

The main focus was on malware protection to determine the success rate for each antivirus software. Thus, I used between 7,000 to 310,000 files for each individual type of scanning. Additionally, I included 10 malware-infected files to stimulate a threat and see whether an antivirus detects it.

Overall, here are the main criteria I gave the most consideration during my assessment:

• Windows app. An antivirus must offer an easy installation setup, a streamlined desktop app, and, above all, consume as few resources as possible.
• Independent lab tests. Though I performed loads of testing myself, relying on lab results is important. Independent sites conduct regular tests detailing malware protection, ease of use, and other essential points.
• Real-time malware protection rate. After all, the job of an antivirus is to safeguard your PC against online and offline device-based dangers. All must be detected and prevented in real-time. Hence, my top recommendations boast a proven success rate of 98% to 100%.
• Regular updates. I ensured that my picks are updated regularly, thus making them ready against advancing cyber threats.
• A number of false positives. False positives are antivirus software reading wrong analytic information and stating that a file or a website is a threat, which is false. I made sure that my top picks sprang none to a maximum of 5 false positives throughout the testing period.
• Additional security features. It’s great if antivirus has additional features. I looked for a password manager, a VPN, ransomware or phishing prevention, cloud storage, or parental control.
• Pricing. Naturally, the software shouldn’t be attainable only for several due to its cost. For this reason, I considered antivirus pricing and plan flexibility, offering no less than 3 tiers.

TotalAV was the best antivirus for Windows 11 because it met all these criteria and performed best during the tests. The well-rounded service offers the most to its customers and takes care of their online security.
