1. Usability

Is Windows Defender good enough for your Windows 10

This is one area where Windows Defender can hold its own against any other third-party antivirus solutions out there. Being a part of the OS, it has seamless integration with the OS and has a user interface that is smooth and no one can complain about. Also, it runs silently in the background performing live threat analysis without you ever having to even think about having or checking for antivirus. Any external media that is connected is automatically scanned.

So, for usability we give it 9/10.

2. Performance

One of the major complains with antivirus is that is hogs up loot of the memory and process. That will be the case for any antivirus you use. To perform the test on performance we used a laptop with 8GB of RAM and i7 4th gen processor and put it on varying number of loads in the background while performing our daily usage in the foreground.

When at idle and having next to nothing to scan, defender was virtually invisible running silently in the background which is better than most of the antivirus out there. Putting it in load by putting a single large file also fared very well. It took up only around 300MB of RAM and 2% of the process. But for large number of small files it started to shake, taking up some huge amount of process and good chunk of RAM. Where we start to see the antivirus falling apart is when it processes threat detected by removing it or quarantine it. During this process you can just wish it finishes fast so you can get back to your work.

So, for performance we give it 7/10.

3. Protection

At the end of the day why we use antivirus is for protection. As for Windows Defender, this is where is complete falls apart.

We used AV-TEST and other tools for analyzing protection level given by Windows Defender. And according to our tests it was able to stop 86% of the malware and 53% of malware URLs. While 86% sound a good number, for malware detection it is considered a pretty poor. And as for blocking malicious URLs it barely scratches the surface.

So, for Protection, we give it 5/10.

While the tests show lower protection against more of hypothetical scenario, in the real world the windows defender performs well on most of the malwares encountered for an everyday user. This saves on computer resources, while having a practically great protection.

At the end of the day antivirus is just a tool, without secure browsing habit, any PC can get infected. As for Windows Defender, if you have a somewhat decent knowledge on secure browsing habits or don’t want to pay any fee for another antivirus you will be perfectly fine with Windows Defender.
