Windows Defender – Always Free

Windows Defender has no setup needed. It is lightweight, and has an average detection rates.

Furthermore, Windows defender is a basic, free, as well as real-time protection solution which is capable for an average PC user who sticks to mainstream websites.

Kaspersky – Features

Kaspersky Free

First of all, the Kaspersky Free is the company’s first AV offering? This particular free software easily protects you against various kinds of malware threats, however, it is quite barebones when it comes to innovative security-related utilities as well as features. Well, it’s probably better compared to nothing. On a side note, Kaspersky’s premium options are certainly better.

Overall, in this quick rundown, we determined that the Kaspersky is the winner as it offers more sophisticated feature with its many plans. ON a side note Windows Defender doesn’t really have much to offer.

Malware Protection

For the most part, Malware protection is the priority of all AV software out there. That’s why whatever software gives better anti-malware features could be the smart pick. Now in order to determine which AV software is better when it comes to protection, let’s take a look at the lab results from two unbiased security companies.

The first company is AV-test.org. They utilize an s coring metric of one to six. Obviously the six is the highest score that can be obtained. Their latest two-round evaluations were conducted in April 2019.

First of all, both Windows Defender and Kaspersky were able to obtain six out six in the protection evaluations, displaying impressive malware defense capabilities.

On the other hand, an Austrian Lab AV-Comparatives is another independent lab testing firm that we can get unbiased evaluations. In their latest real-world protection test, Kaspersky were able to acquire an Advanced plus award – which is the highest aware one can acquire. It is also due to Kaspersky’s near-perfect malware detection rate as well as low number of false detection results. On a flip side, Windows Defender didn’t really do well on the AV-Comparatives’ tests, as it only earned the second best Advanced award.

When it comes to protection, yet again Kaspersky won. Even though it’s pretty close on the first evaluation, Kaspersky still managed to overpower Windows Defender in the overall protection capabilities.

System Performance

Better AV software doesn’t slow down the performance of your PC. In fact, they put a noticeable impact on the PC’s system resources. Now, to determine which AV software is better when it comes to impact on system performance. Let’s take a look at the independent performance test results.

When it comes to the Performance category that AV-Test performed, Kaspersky obtained a perfect six out of six score. This only implies that it puts minimal impact on PCs while operating in the backend. On the other hand, Windows Defender only got a 5.5 out of six score.

Now, in the AV-Comparatives’ evaluation on April 2019 performance test, Kaspersky was able to overpower Windows Defender as it was able to acquire the Advanced Plus award. The Windows defender only got the Standard award which is the lowest award featured by AV-Comparatives.

Looking at it, it is obvious that Kaspersky is yet again the winner when it comes to impact on the system.


This particular factor of security product must be intuitive and very easy to use for everyone out there which includes newbies. With that said, let’s try to roundup the interface of Windows Defender versus Kaspersky to see which one offers better User-Friendliness.

For the most part, Windows Defender’s interface can take quite long to get inside to because you need to go a lot of several clicks just to get inside Windows Defender’s options and settings.

Additionally, you won’t be able to operate any scheduled scans with Windows Defender. This implies that each task aside from fast scanning should be undertaken from the dashboard of the software. Users can find all the major operations as they are located on the left-hand side of the screen. This makes it simple to see where to go based on your needs.

All in all, the interface must be simplistic and intuitive along with a sleek visual look.

That said; let’s see what Kaspersky’s user-interface has to offer.

First of all, Kaspersky uses a light and open-frame interface with most of its operation included. Placed at the top, users will see a big banner that indicates whether your PC is safe or not. Found at the bottom of the dashboard, you’ll notice your subscription status, this keep you in the loop for when you want to refresh your plan.

All in all, Kaspersky’s user-interface is very user-friendly and simple as it also comes with a room of customization and modification. All of its primary settings and functions are also easily accessible with just a couple of clicks.

With that said, Kaspersky is definitely the winner of this user-interface matchup since Windows Defender needs a lot of clicks just to get inside its main dashboard.


Let’s be real here, Windows Defender is free. It comes with no paid for any kinds of upgrades. On the other hand, Kaspersky features a free version and a myriad of different premium plans that come at varied price ranges.

Obviously Kaspersky Free is free. On the other hand, Kaspersky Antivirus is the company’s entry level that cost around 30US dollars which is good for acquiring three licenses that can be utilized between computers. Moreover, Kaspersky Internet Security provides three licenses which are given at almost 40US dollars each year.

Additionally, Kaspersky Total Security can also protect up to 3 smartphones, Macs, or Pcs for just almost 50US dollars which is good for a year. And lastly, Kaspersky Security Cloud comes in two varieties which is the Personal and Family. The Personal version only costs as the same as the Total Security while having the capabilities to protect up to five devices per year. On the other hand, Family version cost almost 150US dollars which is good for a year and twenty devices.

With all of these, there’s really no comparison between the two features AV software since Windows Defender doesn’t offer any kind of paid version. If they only feature free plan, then yes. But since Windows Defender only has free, then it’s hard to give verdict on this pricing factor – all in all, no winner on this matchup.

Final Thoughts

For the most part, Kaspersky is a prominent AV software company; this only implies that their security performance is top-notch. Of course, Windows Defender also possesses good quality AV program that is always free for Windows users.

However, the thing here is that Kaspersky offers a lot of features with respective price ranges. But still, if you’re looking for a good investment, then spending a little bit for the security of your information is a smart decision.

On a side note, if you don’t really need any kind of features and just want the basic AV features, then Windows Defender is what you’re looking for. Also if you’re looking for some coupon code and activation code, you might want to check REDDIT.
