All I can say as a IT Support guy since 2007, is that till Windows 8/8.1 appeared with Defender built in, I was doing 3-4 malware cleans/rebuilds a week. Since then with 10 and 11, it's now 3-4 a year and most of those are just adware or a sanity check to delete a legit remote app off a laptop some guy from India made them install. I actually get more 'virus' calls from Apple users now. Unchecky is a handy little tool for keeping stuff clean.

Imagine being infected with 100 different viruses and your inmune system blocks 99% of it, that is how powerfull windows defender is becoming.

It's Amazing to see how windows defender became better overtime.. someday it might become so perfect so that we don't have to look for an alternate antivirus anymore

Would like to see you do the included Windows Defender vs the Paid Microsoft Defender version that is now available with O365 vs something like Malwarebytes across a larger sample base, should be interesting.

I really like this kind of videos. It gives a clear understanding of why is it so important to have cybersecurity.

I’m glad you did this test. You’re right there’s a lot of guys on Reddit who have a lot of opinions, but never seen tests of what Windows Defender can do.

AT LAST .... the channel returned to its originalform(*antivirus Vs malware tests) ,which was the main reason for me being subscribed in the first place !!

Just after fiber connection I installed a Tz 470 SonicWALL then I run defender on all machines on the other side of the SonicWALL in-house which gives better protection than Malwarebytes did installed independently on each computer. Haven't had one problem since installation of these above mentioned items. Thanks for the review you guys are great!

What I like about Windows Defender on Windows 10 and 11, is you don't have to do anything! It goes to work, keeps its mouth shut, runs in the background, only alerts you when needed, and doesn't slow down your PC. If you are carful online, Windows Defender is all that you need. Additionally all the modern brosers have smart screen and download scanning built in, so that really helps!

I would also add if you are using Office 365, it comes with Microsoft 365 Defender, which is a unified enterprise defense suite with advanced capabilities. For example, it proactively hunts for threats, has identity threat protection, dark web monitoring, prevents cross-domain attacks, etc.

The detections were in line with what I expected! Windows defender is so good nowadays and the important thing is that it is not heavy on the system.

Great content! You guys should make a whole series testing all the antivirus on the market like this I’m curious on how my bitfender would hold up and I bet a lot of people are wondering the same about the antivirus they use.

This is the first time I have come across your channel. I "liked" and 'Subscribed" and I do not subscribe to very many channels. I just want to make sure I don't lose track of this channel. Beautiful presentation. I like that you "show your work" instead of just talking about, makes it much more credible and believable. 🙂

Thank you for doing these types of videos. I generally don’t leave comments, but I do value your opinion and your testing. I have always ran a third-party antivirus program such as bit defender, and even that has failed me over the years with info stealers a few years ago I got hit with an info stealer, and just like you said I lost my KZfaq channel took me a long time to get it back

Frankly it really is great to see windows defender doing better over the years. With supply chain issues becoming a greater concern with 3rd party software solutions, having good first party support for viruses, etc is good.

would like to see a full Windows Defender vs. Ransomware/Malware and everything in between. but not in a VM but in a real system with HVCI.

didn't expect these results, windows defender is truly improving!

Appreciate your time and sharing the results of this test.

Great video, very informative! I am not an IT guy or a big computer guy, but I have never trusted windows defender to actually protect my computer, and came into this video not expecting much. But I am glad to see it is actually getting better, I am definitely going to stick with current anti-malware suite, but maybe with my next computer (if defender continues to improve), I won't feel the need to replace it!

Id love an in-depth video about Microsoft Defender for Endpoint, even running this test. Its the Enterprise AV/EDR available with Microsoft 365. We use SentinelOne where I work, but im considering a greater push to move to using it, since its included with our 365 licences. Im too busy right now doing some practical tests with Entra ID Plan 2 so I cant test it myself right now.

Yessss, would love to see video's comparing the popular AV's.

A new day with a new upload from The PC Security Channel is another day of happyness fr

THANKS FOR SHARING! Hjghly needed this as I am currently considering to use defender instead of third party anti-malware.

I remember how I absolutely hated Defender for being "always in the background" and eating RAM when I first moved from W7 to W10" But over time, I've grown quite glad for it being there - And even more so watching this video

I didn't notice any mention or testing of an additional Windows Defender feature known as Windows Defender offline that's now available in scan options. It has the ability to scan the system before the OS loads in the Windows 7 days it required the use of a bootable thumb drive.

I'm really liking defender more and more. Considering I am a sole infrastructure engineer and the business is wanting to use bitdefender mainly, i think potentially having the both of these helps alot from a cloud protection and local.

I have just used Windows Defender for the past few years. Defender had gotten much better recently and I'm not sure if it is worth the price and memory usage of premium AV.

Great video. Really appreciate seeing some testing I can point people to. I agree base defender absolutely fine for the average user. Enterprises environments should have an XDR solution.

Fun fact (00:30): In 2013, the latest version of Windows was Windows 8, which already featured Windows Defender. WD was initially released as a standalone application for Windows XP in 2006 before being directly integrated within the release of Windows Vista

Very insightful, ty for sharing this experiment

Great video! Thanks for posting!

He’s a great videos, very interesting, informative and fun to watch. If I had a need I would definitely hire this company.

I am using Defender only barring the occassional manual scan with MWB but even then 90 % is not 100 %, even if the missed threats weren't major and no malware processes were running. I'd kind of want to see a follow up of trying to run the threats Defender missed one-by-one, did Defender just miss them due to the overload of malware being ran at the same time or does it simpy omit those instances. Defender relies on cloud analysing yeah but even then I'd want to see it work more like "this process is on hold until it is considerd safe" instead of "there are so many processes trying to run that some might slip through". Also MWB being smart enough to determine the threats were being run by a script and terminate the script itself is quite impressive to me, exactly what you'd want from your AV.

This evolution totally passed me by. So thanks for enlightening me.

Very insightful thank you 🙏

Que buen video. Algo que tenía curiosidad pero jamás lo hubiera intentado en mi PC

You so need to make a series out of this with others besides defender

I would like to see you do this on multiple anti-maleate programs.... Can you try AVG next time?? I wish yo would have also tested Defenfer with the cloud turned off....just for the "Smiles and Giggles factor".

TBH I've had so many problems with third party antivirus software breaking things like Windows updates or false-positive blocks (like once the windows logon service got blocked) that I just run Defender now.

Curious about running it behind a netgear armor enabled router with the bitdefender companion installed. Might have to do similar testing

Would be interesting to see the results with Windows running in S mode. Its just about possible to do everything most users would want to do under S mode, and malware likely wouldn't stand a chance.

I completely forgot about XP's endless pop-up screens, good times lol! I remember once i really tried to close them all for like 10 minutes but it was popping up and up so i began preparations for a format))

When you mentioned the like and suscribe, did you choose to have the button highlight? Is that a thing? Because on my pc it just hightlighted it when you said that

Good to see much improved detection rate of MS Defender. On the other hand they (Micro$) want to control you more and more. I use Kaspersky Total Security - NOT the new Plus version which pops up all sorts of things I am annoyed with. Also use Malwarebytes, though Kaspersky complains as not compatible. Oh yeah Windows is running virtualized. My choice of backup is Acronis.

Cool info, thanks for sharing, well done :)

We have been using Heimdal at our company for a while now, and we really love it :)

Amazing video I was always wandering if windows defender is good.. btw any views on panda antivirus?

Very interesting, can you try the browser apps plugins to see how good they protect ?

Thank you for video and your effort. Could you test the OpenEDR product please?

Hi, thanks for your excellent video! While reviewing this one, I wondered why should I renew my Kaspersky subscription. If windows defender is acceptable, why should we go for a payable antivirus Thanks for your opinion on this matter

Do you have a video of how you have this special set up so it won't attack your home network. Considering that you are running this on a virtual machine, do you use this computer on its own for virus testing or do you also use it for personal use? I would like to run some forensics on my own set up so I can make sure that I'm as secure as possible.

thanks for posting!

would it be easier/better or at least interesting at all to just run that python script (or slightly modified) to slam them all on a usb drive that you then rig to be executed upon plugging it in, or just for extra security in testing, executed via some other script on it?

Its become so much better than it was back in Windows Vista/7 days, go to a few questionable sites/download from questionable sources back then and you used to be screwed, nowadays no issues at all with any kind of malware/virus. With that said, I've had issues every once in a while where it wouldn't allow me to save files in Documents folder.

Thank you for doing these tests. Could we possibly have a review of HP Wolf Security ? This now comes preinstalled on most laptops manufactured by HP and works alongside Windows Defender.

This is great, we need more of this

I'd like to see that same test versus Microsft Defender and Defender for Endpoint as part of the M365/O365 security offerings

Hey Leo, just wondering, what would you recommend as a free antivirus?

interesting video as always many thanks I'm all ways looking for ways to spot and remove viruses besides just hoping my antivirus's will solve the issue

Windows defender might be the most powerful antivirus on the market right now, assuming that you have enabled cloud analysis and the automatic sample submission, it's incredibly aggressive and is quick on the uptake when facing new/unknown malware.

A potential gap in your analysis: is Malwarebytes blocking threats as the links themselves are known to be threats or is it blocking based on scan and behaviour of the files? I can't quite say as no idea what your script does but likely downloads first..

Thx for for doing this video, still i have a question. How about iobit systemcare and malware fighter?

I want to see more from Malwarebytes, since its smart enough to detect an active attack vector. Also how its performing if web is unviable ...

I would like to see a Linux distribution under the same circumstances. A random Linux distribution and user vs. 100 malware sites.

Thank you for all you do

Could you do a comparison with Microsoft Defender for Endpoint?

Sacrificial frozen state VM's are amazing for testing whether or not something is sketchy. you can run anything on them and the moment you reboot its clean. just make sure its not on your primary vlan..

I have a question about the malware you've used, does it have Anti VM / Anti Debugger enabled? or is this an off topic question, and if it does have these types of protection doesn't that make the detections semi broken due to the virus self killing itself before defender caught on?

I love Malwarebytes, I've been using them in my personal environment for years. At work, we only run Windows Defender (it's free). I'm perfectly happy with the security it provides,

Hey pc security if you save some password folders in your computer the virus can extracted it is bad idea to store inside the cpu . Use paper or book to write it down for later if you forget the password the book already save information and it wouldn’t loose your login but if the virus hits there is no passwords store in it it can’t steal passwords. It that will prevents hacker steal ?

Can you do bulletproof west vs top 100 most powerful weapons next?

As someone that just built their first pc is defender the recommended go to these days or should I get something like Malwarebytes too?

Thank you so much , I've started using anti-virus software in 2016 and still was using it until i saw your video thank uuu

I would definitely like to see bigger test. Or performance impact of different antiviruses. Or even for gaming.

I would love to see how windows defender vs an adblocker like ublock origin with all blocksites added. I have just been using adblocker for years and never have malware since.

I realize this video is 5 months old and possibly there is an answer in the comments or in another video but I haven't seen one yet, is there a comparison between Defender and Defender for Endpoint via 365?

For UEFI malware infection validation don't you need to reboot and then run the tests? Or was that done?

Amazing that they know all these malware sites and they haven't destroyed and removed them strange world

Could you test Avast ONE again ;) Would be nice.. Keep it up

Can you do a malware analysis on kms, mas and other forms of cracked installers

Windows defender + malwarebytes + he's browser extension = perfection

When did that VM last run its defender intelligence update before the test was run?

using norton 360 delux here for up tp 5 devices here also got malwarebytes as well

I don't know sometime Windows defender not help or malwarebytes My friend got hacked week ago likely download some exe I tried to give him malwarebytes but doesn't log anything Like is the virus is in you or it is hard to find it is like info stealer Can you teach us how to find the virus that hides through security programs?

Question . Do we need to run windows ramsonware protection on ? It IS giving me a Lot of bsod blocking even AMD programs

It's nice to see how Windows Defender became so much better because i really don't want to download any third-party anti virus cuz some anti virus takes to much memory

Could you please do ESET test someday?

Tip for next video - please dont block the process explorer - it's nice to see what is happening in real time to executables.

It seems that Windows Defender was active (icon bottom right with green checkmark at 7:00) during the Malwarebytes test. Was this the case?

Great Stress-Test and good to know and see Windows Defender's performance evolution overtime. How about scripting random websites visits in a 24hr period and see how Windows Defender, and the competition, perform, on an average Jack & Jill PC? ¯\_⚆◡⚆_/¯

Interesting. I assume Bitdefender or Kaspersky particularly are a bit better of course. Thanks for the tests.

I would love to see if you could do a video for best anti virus out there for gavers(pcs)

For us non-discord users and generally entry-level 'enthausiasts', would you be interested in (re)making a how-to on general IT protection? Mainly aimed at singular PC systems, but perhaps adding to that with a router-based stuff. I was thinking of three levels: entry level / basic, intermediate and hardcore. Where the entry level would be like: vpn, additional malware and virus protection, browser protection, etc.). And intermediate and hardcore could include more extensive and intesive actions, such as router changes or additions, VM ware, the Crowdsec thing you mentioned, etc. (don't know any better examples, as I'm not that knowledgeable on these topics). I find it fairly difficult to harvest trustworthy and/or useful recommendations on this subject, where the level of explanation doesn't exceed the 'beginner' level of understanding.

Dude can u make a clip about everthing we can erease on win 11 and 10 like stuff as remote computer if not needed etc ????

Just a question. If an info stealer does steal info off my device, would services like my bank which require 2FA, OTPs etc still be compromised? Because to do transactions etc having the password isn't enough

The only problem i have with defender is that when i am doing a Full scan, the ui of the progress bar, remaining time and total files scan just stop. I can navigate through the program, so it is working, but this bug worries me became i don't know what is happening. Any help would be useful, thanks.

Would love to see this against Bitdefender with GravityZone and EDR or XDR.

hello just wondering on a new windows install and when doing a full scan it freezes around the 3/4 mark, is it because of corruption?

I know this is kinda too late, but, is Librewolf a good option as "private" browser?

I would like to see you make an seriously infected system to operational again without installing new windows and using your skillets . If it is possible
