Microsoft’s Windows Defender has come a long way in terms of its cybersecurity capabilities. It used lớn be really bad, but recently, Microsoft has turned Defender inkhổng lồ a pretty decent không tính phí antivi khuẩn.

You watching: Windows defender win 10 có tốt không

For example, Defender now includes sandboxing và cloud-based malware detection — boosting overall protection và making threat detection faster.

But even with these changes, our readers keep asking us these 3 questions:

Can Windows Defender handle all types of malware, including advanced ones lượt thích ransomware và spyware?Is it fast enough lớn remove threats without slowing down my PC?Is it good enough to use as a standalone antivirus, or is there something better?

I spent several weeks testing out both Microsoft’s Defender and all of the top antivirus programs on the market, ranking them on malware detection rates, system performance, scan speeds, overall mạng internet security protection, và customer support.

For starters, Windows Defender failed to lớn blochồng many viruses that other programs easily caught, & that’s because Microsoft doesn’t issue enough regular updates khổng lồ the Defender database lớn make it able lớn detect the lathử nghiệm threats. And let’s say that you bởi vì get a virus, Microsoft isn’t going to help you — they’ll just tell you that you should’ve had another antivirus installed!

So is it good enough? Not really…

After comparing Microsoft’s antivirus vs. other third-party antivi khuẩn programs, I found several antivi khuẩn programs that are much better than Windows Defender.These third-buổi tiệc ngọt antiviruses have more effective sầu malware scanners, are easier to lớn use, and come with better and more advanced cybersecurity protections.


Short on time? Here’s a quiông xã summary of the best alternatives khổng lồ Microsoft’s Windows Defender in 2021:


About Microsoft Defender Antivirut (aka Windows Defender)

*

There are many reasons khổng lồ lượt thích Windows Defender especially as Microsoft has worked really hard to improve it over the last few years. It now offers:

Real-time threat detection.Firewall & network protection.Protection against phishing sites.System performance reports.Hardware security.Parental controls.

Microsoft’s Defender is pretty good at detecting malware files, blocking exploits & network-based attacks, và flagging phishing sites. It even includes simple PC performance và health reports as well as parental controls with content filtering, usage limitations, & location tracking. Because Windows Defender now includes all of these useful features, users are wondering whether they can rely on Defender alone khổng lồ protect their computers or need khổng lồ use a third-buổi tiệc ngọt antivi khuẩn.

Is Microsoft’s Defender Antivirus Good Enough?

I ran Defender through the same rigorous tests that I use for all third-buổi tiệc nhỏ antivi khuẩn products.

I downloaded around a thous& malware files — including viruses, trojans, ransomware, adware, cryptojackers, keyloggers, & rootkits — in order to lớn thử nghiệm the disk scanning & real-time protection functions.

I also navigated to dozens of phishing sites on a few different browsers to lớn assess Defender’s anti-phishing capabilities, và I simulated exploit và network-based attacks to lớn kiểm tra Microsoft’s built-in firewall và network protections.

In addition to all of this testing, I measured CPU performance during various situations — lượt thích while using high-powered programs during disk scans — as well as testing every single feature to lớn assess its overall ease of use.

In the over, I found a ton of issues with Microsoft’s Defender — here are my main complaints:

Malware detection rates are lower than many third-các buổi tiệc nhỏ competitors.Parental controls are limited to the Microsoft Edge browser.The main user interface is clunky & not easy lớn navigate.PC system health report is basic (no performance boosting or system cleanup).There’s no cross-platkhung tư vấn (except for enterprise users). Lacks additional tools which third-tiệc nhỏ antiviruses have sầu, like aVPN, password manager, dark web monitoring, or identity theft protection.

The truth is that Microsoft Defender is closer than it’s ever been lớn being competitive with third-buổi tiệc ngọt internet security suites… but it’s still not good enough.

Sure, Defender is không lấy phí, but there’s a reason why mạng internet security suites cost money, not the least of which is that Microsoft is not a cybersecurity company! In the past couple of years, Microsoft has issued updates that broke both the antivirus’s full & quiông chồng scan features, caused repeated skipping of malicious files, and even caused the whole security apparatus to crash!

This kind of sloppy unique control simply doesn’t happen with a dedicated antivi khuẩn software developer.

If you value the security of your PC & all of your online accounts, you need khổng lồ invest in higher-quality internet security software.


Top Brands That Didn’t Make the Cut:

Quichồng Heal. Quiông xã Heal is a pretty decent program. Its virut protection capabilities are comparable lớn Windows Defender, and it’s got a wide range of internet security packages to choose from. That said, I think these packages are too overpriced for what they offer, và all of the products on this menu offer better value.

🥇1. Norton 360 — Best Antivi khuẩn Alternative khổng lồ Microsoft’s Windows Defender in 2021

*
Norton 360 is better than Windows Defender in every aspect — it has higher malware detection rates, better mạng internet security protections, more additional features, & coverage for more platforms.

In my head-to-head malware demo, Norton caught way more malware files than Defender — Norton scored a perfect 100% malware detection rate, blocking several tricky spyware and ransomware files that Defender missed.

And when it comes to lớn internet security tools, Defender just can’t compete.

Norton 360 includes:

Stronger anti-phishing protection. More complete parental controls. Extra features like a VPN (virtual private network) và password manager.And a lot more…

Microsoft recently expanded Defender’s web protections khổng lồ third-party browsers like Chrome and Firefox, but in my testing, Norton’s anti-phishing protections caught a significantly larger number of suspicious websites than Defender — including malicious link in emails và text messages.

Norton 360also has a wide range of additional features that Windows Defender doesn’t have — including an excellent VPN which provides encrypted access to 30+ servers around the globe, barely affects mạng internet speed, and removes geo-restrictions. Norton also has a really good password manager with all of the essentials, like auto-saving, auto-filling, và biometric login, as well as extras such as a password auto-changer (which only the best password managerslượt thích DashlaneandLastPasshave).

Norton 360 is available ina variety of packages. Norton 360 Standard is a good choice for users looking to lớn protect only 1 device. Norton 360 Deluxe covers 5 devices và includes excellent parental controls, which offer location tracking as well as the ability khổng lồ bloông xã và schedule usage for specific apps. Norton 360 with LifeLock(US only)adds a $1 million identity theft insurance policy.

Bottom Line:

Norton 360is the best Windows security suite on the market— it provides a substantial improvement on all of Defender’s protections, và it offers a ton of extras that Microsoft doesn’t include with its built-in antivirut. Norton is also easier lớn use than Windows Defender, has a variety of pricing plans for every budget, và offers a generous 60-day money-back guarantee.

🥈2. Bitdefender — Better Cloud-Based Scanning Engine (with Excellent Additional Features)

*
Bitdefender is fast, lightweight, và has a much better cloud-based scanning engine than Microsoft’s Defender. Bitdefender’s malware scanner caught all of my demo malware during a full system scan, & it barely had any impact on my computer’s performance. Even though Windows Defender is also partially cloud-based, it still slowed down my system during scans.

A lot of users don’t want to lớn nâng cấp to a third-các buổi tiệc nhỏ antivi khuẩn because they think it will be more complicated than Windows Defender’s automatic security protections — but Bitdefender is actually even more hands-off than Defender is.Bitdefender’s “Autopilot” feature automatically analyzes your files, your network, & your online activity khổng lồ create a phối of default protections that run seamlessly in the background.

I really lượt thích Bitdefender’s interface, which displays all of Bitdefender’s features in a single window. Here are some of Bitdefender’s additional security features:

Better website protections. Simpler interface.Better parental controls.Extra tools lượt thích VPN, webcam protection, PC tune-up, etc.

Bitdefender has some of the strongest web protections of any antivirus on the market. Its VPN is extremely fast, providing better connection speeds than a lot of standalone VPNs. The parental controls are also excellent — they provide tiện ích usage limits, online content filtering, và even geo-fencing which alerts you when your children’s devices leave sầu a safe area.

Bitdefender has several antivirut packages, but Bitdefender’s premium Total Securitypackage — which covers Windows, macOS, Android, & iOS — includes more features than almost any antivirus. Users on a budget can also check out Bitdefender’s less advanced antivi khuẩn packages, which still offer really good PC protection.

Bottom Line:

Bitdefender has a powerful cloud-based anti-malware scanner with perfect detection rates as well as a ton of really good mạng internet security features that expand on Microsoft’s basic protections. Bitdefender has anti-phishing, a VPN, parental controls, a password manager, system tuneup tools, & lots more, all inside a well-laid-out & intuitive sầu dashboard. All of Bitdefender’s plans come with a 30-day money-baông chồng guarantee.

*
TotalAV has better detection rates và is much easier khổng lồ use than Microsoft’s Windows Defender. TotalAV’s malware engine is lightweight, fast, & constantly updated khổng lồ detect the lachạy thử malware threats. In my tests, TotalAV identified & removed more than 99% of the malware samples I downloaded to lớn my virtual PC, including sophisticated malware files like ransomware và cryptojackers that Windows Defender missed.

I also found it very easy lớn access and use all of TotalAV’s features & functionalities — the dashboard is more intuitive, simpler khổng lồ navigate, & better designed than Windows Defender, making TotalAV a particularly good choice for non-tech-savvy users.

TotalAV also includes some really good extra features which Windows fails lớn include in its built-in protections — including a VPN, system tuneup tools, & identity theft protections.

TotalAV’s system cleanup feature includes a ton of useful features, lượt thích a junk cleaner, application uninstaller, startup manager, và browser cleanup. With all of these features included in the same convenient window, I was able to lớn get my nephew’s backed-up Acer máy tính running like new in a matter of minutes.

TotalAV’s identity theft protections are very good too — unlike most competitors that offer identity theft protections for US users only, TotalAV also covers Canada and some European countries. The identity theft protections are only offered with the company’s premium Total Security plan — users looking for a more affordable option can opt for TotalAV Antivi khuẩn ProInternet Security,which both offer a good mix of features at an affordable price.

Bottom Line:

TotalAV is much easier to lớn use than Windows Defender và comes with good malware protection và great PC optimization tools lớn enhance device performance.I like TotalAV’s premium identity theft protections as well, but they’re only available on TotalAV’s premium Total Security plan.

*
Avira Free Security for Windows provides strong anti-malware scanning và tons of high-chất lượng extra features inside its không tính phí version— it’s currently ranked #1 as thebest free Windows antiviruson the market.

Avira’s cloud-based malware scanner performed really well during my tests, detecting 100% of the malware sample files on my device — far better than Windows Defender.

Avira’s free antivirusalso includes features that Windows’s antivirut doesn’t provide, including:

Safe Shopping browser extension.Free VPN (with 500 MB of data per month).Extras lượt thích performance optimization tools & password manager.

I really lượt thích Avira’s Safe Shopping browser extension, which blocks web trackers, intrusive advertisements, and phishing sites — outperforming Windows Defender’s “SafeScreen” in terms of security and convenience.

Avira’s VPN is also pretty good — but the free version is limited to only 500 MB of monthly data, which is barely enough to kiểm tra your emails. Users looking for a VPN with unlimited browsing data, advanced system optimization, và thiết bị di động protections should check out Avira Prime— it offers coverage for up khổng lồ 5 users across all operating systems.

Bottom Line:

Avira’s real-time detection and malware scanning engine performed much better than Microsoft’s Defender in my tests — it’s my favorite miễn phí alternative lớn Defender.

5. McAfee — More Internet Security Tools

*
McAfee Total Protection is an excellent internet security suite with much better web protections & network safeguards than Windows Defender’s. McAfee’s malware scanner is also one of the best on the market, outperforming Windows’s antivirut và catching 99% of the nearly 1,000 malware files on my PC.

McAfee also offers a huge improvement over the built-in protections included with Windows 10.

McAfee has:

More advanced firewall. Better anti-phishing protection. Additional protections lượt thích a Wi-Fi scanner và a VPN.

Windows Defender has a pretty good built-in firewall, but McAfee’s “Smart Firewall” provides a ton of options that Defender doesn’t offer. You can use the Smart Access feature to let McAfee’s firewall analyze incoming và outgoing threats, activate the Stealth Mode khổng lồ hide your PC on public networks, or use Lockdown in an emergency to lớn bloông xã all traffic inkhổng lồ and out of your computer.

McAfee also has an excellent Wi-Fi scanner that actively scans your network to lớn let you know which devices are currently logged inlớn your Wi-Fi network. The Wi-Fi scanner even offers notifications if new users try lớn gain access lớn your network.

McAfee Total Protection is available for 1, 5, or 10 devices, and it provides very affordable 2-year subscription plans which are around the same price as some competing antiviruses’ 1-year packages.

6. BullGuard — Better Performance for Gamers

*
BullGuard has a really good anti-malware engine & some unique perks for PC gamers that aren’t included with Windows’s antivi khuẩn. BullGuard và Microsoft’s Defender both use machine learning to lớn catch malware on your system — and they’re both automatically updated through the cloud — but BullGuard has higher detection rates against zero-day attacks.

BullGuard has a very good game booster that both suspends scans and notifications while gaming & reallocates system processes across multi-core processors— so that your CPU can put as much power as possible into lớn running your games. In my testing, this game booster significantly increased my frame rate and load times across a wide variety of games. By contrast, Defender doesn’t have sầu any sort of gaming mode, so it can (và frequently does) interrupt gaming with scans or notifications.

BullGuard’s VPN is really good, too, but it’s pretty frustrating that the VPN is only offered as an additional subscription, even with BullGuard’s top-tier plans.

But BullGuard is reasonably priced, offering the game booster with all 3 of its antivirus packages. The more advanced plans offer some useful extras for a price that’s cheaper than most competing antiviruses.

Bottom Line:

BullGuard provides advanced anti-malware protection và a quality game booster for PC gamers. BullGuard also offers some helpful internet security tools, but the VPN is only available as a separate purchase. All BullGuard premium plans are backed by a 30-day money-back guarantee.

7. Kaspersky — More Advanced Parental Controls + Good Financial Protections

*
Kaspersky offers a good malware scanner and website protections which are more advanced than the ones offered by Defender. In terms of malware protection, Kaspersky ranks with the top antiviruses on the market, detecting malware more effectively than many competitors, including Microsoft’s Windows Defender. However, Kaspersky didn’t run as smoothly as Defender on my computer, causing some slowdown issues during virut scans.

On the other hand, Kaspersky has good parental controls — much better than Defender’s, ranking with Norton, Bitdefender, và McAfee for the top antiviruses with parental controls. Kaspersky’s parental controls provide device usage limits, online content filters (including YouTube ứng dụng filtering for Android), & geo-fencing controls lớn ensure your kids remain in a safe area.

Kaspersky also offers good financial protections with its Safe Money browser. This feature offers a sandboxed browser window and on-screen keyboard for secure online transactions — it’s a simple và helpful way to lớn improve online privacy.

Kaspersky also has some website protections that aren’t included with Windows Defender, like a password manager và a VPN with a data limit of 200 MB/day.

Kaspersky Anti-Virus and Kaspersky Internet Securityare pretty decent plans which cover up to lớn 5 users, but families looking for good parental controls will want to lớn tăng cấp lớn Kaspersky Total Security,which offers parental controls as well as a password manager for up to lớn 10 devices.

Bottom Line:

Kaspersky is a full-featured antivi khuẩn suite with a better malware scanner than Microsoft’s Defender, as well as some really useful security tools.

All of Kaspersky’s plans come with a 30-day money-baông xã guarantee.

8. Panda — More Extras (& Flexible Pricing)

*
Pandomain authority Dome is a good anti-malware program with high detection rates, decent extra features, và a variety of plans and payment options. In my testing, Panda detected malware about as accurately as Windows Defender, catching the majority of the malware files on my kiểm tra PC, but it missed some newer adware & ransomware files that competitors like Nortoncaught.

Panda also includes a ton of extra features that Windows’s antivi khuẩn doesn’t offer, including a really good VPN— it uses Hotspot Shield’s VPN giải pháp công nghệ to lớn provide fast and encrypted website access to lớn 20+ servers around the globe.

I’m also a huge tín đồ of Panda’s Rescue Kit, a bootable version of Panda which can be saved lớn a USB thumb drive sầu. In the sự kiện of a really bad malware infection, the Rescue Kit can restart a computer và open Panda from the thumb drive, allowing you khổng lồ use Panda’s cloud-based malware technology to lớn disinfect the system. Neither Defender nor the other antiviruses on this list have sầu a similar feature lớn Panda’s Rescue Kit.

Panda offers 5 different packages, including a không lấy phí plan for users on a budget. You can choose khổng lồ protect 1, 3, 5, 10, or an unlimited number of devices, & all of the plans offer monthly, yearly, 2-year, và 3-year subscription options.

9. Malwarebytes — Good Anti-Malware Protection for Budget Users

*
Malwarebytes offers advanced protection against a wide range of malware threats, including zero-day attacks & ransomware. Malwarebytes’s scanning engine is just as high quality as top competitors lượt thích Norton and McAfee — I was pleasantly surprised that Malwarebytes caught every single malware sample during my tests.

Malwarebytes’s dashboard is easier to lớn use than Defender’s dashboard. This is lớn be expected, though — Malwarebytes doesn’t really have any extra features, besides an automatic anti-phishing filter (that works far better than Microsoft’s built-in protections).

Users looking for an additional layer of online privacy will be happy to see that Malwarebytes now offers a secure VPN — it’s pretty good, providing encrypted access to lớn servers around the globe, but it wasn’t as fast as Norton’s VPN in my testing.

Malwarebytes Free offers on-dem& disk scanning without real-time protection — I wouldn’t recommover it, especially when Malwarebytes Premiumonly costs a few bucks a month. You can also check out the Malwarebytes Premium + Privacyplan if you’re looking for malware protection & a secure VPN.

Bottom Line:

Malwarebytes provides excellent malware protection and anti-phishing controls, but not much else. Malwarebytes’s scanning engine is as accurate as Norton & McAfee, và the bundled VPN is also pretty good. Malwarebytes comes with a 30-day money-back guarantee.

10. Trkết thúc Micro — Good Phishing Protection

*
Trkết thúc Micro offers some notable improvements over Microsoft’s built-in protections. Trover Micro’s antivirus scanner performed well in my testing, catching around the same amount of malware as Microsoft’s Windows Defender and providing fast disk scans & lightweight real-time protection.

I also really liked Trend Micro’s anti-phishing protections, which provide color-coded rankings for Google searches and automatically block unsafe links from emails, texts, and pop-up ads.

While these mạng internet security features are really good, Trend Micro’s parental controls and VPN are not nearly as good as the offerings from competitors like Norton và McAfee.

Trend Micro offers 4 different plans: Antivirus+ Security — Real-time protection, anti-phishing, & gmail scam filter for 1 PC. Internet Security— Adds parental controls & system tune-up for 3 PCs. Maximum Security— Adds password manager for 5 PCs, Androids, iOS, or macOS devices. Premium Security Suite— Adds dark website monitoring, priority tư vấn, & VPN for up khổng lồ 10 devices.

Bottom Line:

Trkết thúc Micro offers good malware detection rates và excellent anti-phishing protection, but its additional features are hit or miss.

Trkết thúc Micro is definitely an improvement over Microsoft’s Windows Defender, but I wasn’t impressed with its parental controls or VPN. There is a 30-day money-baông chồng guarantee for all of Trover Micro’s plans.
