Windows defender có tốt không


Microsoft’s Windows Defender has come a long way in terms of its cybersecurity capabilities. It used to be really bad, but recently, Microsoft has turned Defender inlớn a pretty decent không tính tiền antivirus.

Bạn đang xem: Windows defender có tốt không

For example, Defender now includes sandboxing & cloud-based malware detection — boosting overall protection & 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 and spyware?Is it fast enough khổng lồ remove sầu threats without slowing down my PC?Is it good enough to lớn use as a standalone antivirut, or is there something better?

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

For starters, Windows Defender failed to block many viruses that other programs easily caught, and that’s because Microsoft doesn’t issue enough regular updates khổng lồ the Defender database khổng lồ make it able to detect the lakiểm tra threats. And let’s say that you vì chưng get a vi khuẩn, Microsoft isn’t going khổng lồ help you — they’ll just tell you that you should’ve had another antivirut installed!

So is it good enough? Not really…

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

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

About Microsoft Defender Antivirus (aka Windows Defender)

There are many reasons lớn lượt thích Windows Defender

especially as Microsoft has worked really hard lớn improve sầu it over the last few years. It now offers:

Real-time threat detection.Firewall và 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 to protect their computers or need khổng lồ use a third-buổi tiệc ngọt antivirut.

Is Microsoft’s Defender Antivirus Good Enough?

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

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

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

In addition lớn 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 lớn assess its overall ease of use.

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

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

The truth is that Microsoft Defender is closer than it’s ever been khổng lồ being competitive with third-các buổi party mạng internet security suites… but it’s still not good enough.

Sure, Defender is miễn 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 and quiông chồng scan features, caused repeated skipping of malicious files, & even caused the whole security apparatus lớn crash!

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

If you value the security of your PC and all of your online accounts, you need to invest in higher-chất lượng mạng internet security software.

Top Brands That Didn’t Make the Cut:

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

🥇1.Norton 360 — Best Antivirus Alternative lớn Microsoft’s Windows Defender in 2021

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

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

And when it comes 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) and password manager.And a lot more…

Microsoft recently expanded Defender’s website protections khổng lồ third-tiệc ngọt browsers like Chrome & Firefox, but in my testing, Norton’s anti-phishing protections caught a significantly larger number of suspicious websites than Defender — including malicious links 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 lớn 30+ servers around the globe, barely affects mạng internet tốc độ, & removes geo-restrictions. Norton also has a really good password manager with all of the essentials, lượt thích auto-saving, auto-filling, và biometric login, as well as extras such as a password auto-changer (which only the best password managerslike DashlaneandLastPasshave).

Norton 360 is available ina variety of packages. Norton 360 Standard is a good choice for users looking to protect only 1 device. Norton 360 Deluxe pháo covers 5 devices & includes excellent parental controls, which offer location tracking as well as the ability lớn blochồng & 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 antivi khuẩn. Norton is also easier khổng lồ use than Windows Defender, has a variety of pricing plans for every budget, & 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, và 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 lớn tăng cấp to a third-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, and your online activity to create a phối of mặc định 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 like VPN, webcam protection, PC tune-up, etc.

Bitdefender has some of the strongest web protections of any antivi khuẩn 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 ứng dụng usage limits, online content filtering, & even geo-fencing which alerts you when your children’s devices leave a safe area.

Bitdefender has several antivirut packages, but Bitdefender’s premium Total Securitypackage — which covers Windows, macOS, Android, và iOS — includes more features than almost any antivirus. Users on a budget can also check out Bitdefender’s less advanced antivirut 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 internet security features that expvà 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 dashboard. All of Bitdefender’s plans come with a 30-day money-baông xã guarantee.

In my tests, TotalAV identified & removed more than 99% of the malware samples I downloaded to my virtual PC, including sophisticated malware files like ransomware và cryptojackers that Windows Defender missed.

I also found it very easy to access và use all of TotalAV’s features and functionalities — the dashboard is more intuitive, simpler to navigate, và 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 to 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, & browser cleanup.

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 và some European countries.

Avira’s không tính phí antivirusalso includes features that Windows’s antivi khuẩn 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 sầu advertisements, & 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 lớn check your emails. Users looking for a VPN with unlimited browsing data, advanced system optimization, và Smartphone protections should check out Avira Prime— it offers coverage for up lớn 5 users across all operating systems.

McAfee Total Protection is an excellent internet security suite with much better website protections & network safeguards than Windows Defender’s. McAfee’s malware scanner is also one of the best on the market, outperforming Windows’s antivi khuẩn 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 and 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.

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 antivirut. BullGuard and 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 và notifications while gaming and 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 và 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 antivi khuẩn packages. The more advanced plans offer some useful extras for a price that’s cheaper than most competing antiviruses.

Kaspersky offers a good malware scanner và 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 virus scans.

On the other hvà, Kaspersky has good parental controls — much better than Defender’s, ranking with Norton, Bitdefender, & McAfee for the top antiviruses with parental controls. Kaspersky’s parental controls provide device usage limits, online nội dung filters (including YouTube phầm mềm filtering for Android), và 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 & helpful way khổng lồ improve online privacy.

Kaspersky also has some web 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 & Kaspersky Internet Securityare pretty decent plans which cover up to 5 users, but families looking for good parental controls will want khổng lồ 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.

8. Panda — More Extras (& Flexible Pricing)

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

Pandomain authority also includes a ton of extra features that Windows’s antivirus doesn’t offer, including a really good VPN— it uses Hotspot Shield’s VPN giải pháp công nghệ to provide fast và 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 to lớn a USB thumb drive. In the event of a really bad malware infection, the Rescue Kit can restart a computer and open Pandomain authority from the thumb drive sầu, allowing you to lớn use Panda’s cloud-based malware giải pháp công nghệ khổng lồ disinfect the system. Neither Defender nor the other antiviruses on this danh mục have a similar feature khổng lồ Panda’s Rescue Kit.

Panda offers 5 different packages, including a không tính phí plan for users on a budget. You can choose to protect 1, 3, 5, 10, or an unlimited number of devices, and all of the plans offer monthly, yearly, 2-year, and 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 và ransomware. Malwarebytes’s scanning engine is just as high quality as top competitors lượt thích Norton & McAfee — I was pleasantly surprised that Malwarebytes caught every single malware sample during my tests.

Malwarebytes’s dashboard is easier to use than Defender’s dashboard. This is to be expected, though — Malwarebytes doesn’t really have sầu 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 khổng lồ see that Malwarebytes now offers a secure VPN — it’s pretty good, providing encrypted access khổng lồ 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 recommkết thúc it, especially when Malwarebytes Premiumonly costs a few bucks a month. You can also kiểm tra out the Malwarebytes Premium + Privacyplan if you’re looking for malware protection và a secure VPN.

Bottom Line:

Malwarebytes provides excellent malware protection và 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-baông xã guarantee.

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

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

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

Trkết thúc Micro offers 4 different plans: Antivirus+ Security — Real-time protection, anti-phishing, & email 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 web monitoring, priority tư vấn, & VPN for up to 10 devices.
