Windows Defender will give the report of your PC’s performance. If any issue is detected like battery performance issue, storage capacity issue, the windows is out of date then the Defender will notify you so that you can fix that.

Antivirus vs Windows Defender

What is the Windows Defender

Before I told you before “what is the Windows Defender”? Now, I am going to compare Windows Defender with Antivirus.

We are all familiar with antivirus. Antivirus is also a security protection program of third party developer. Here I will compare from different factor which will help you to understand better way.

1# Costs

In factor of costs the Windows Defender is absolutely free to use and we know that antivirus is costly.

Antivirus program is three types, first one is Antivirus, second one is Total security and third one is internet security. The price of the Antivirus is less then the total Security and Internet Security.

2# Performance

In case of performance both are provide us good performance. But Antivirus is the better in my point of view because it works faster then Defender.

Sometimes it seen that the Defender can’t detect heavy virus where an Antivirus can easily. In case of performance the defender need some improvement.

3# Security

In the security again Antivirus is the best. I am not telling you that Defender not providing us good performance, it is good but not give us performance like an Antivirus.

Antivirus not only protect our computer from virus but also it warns us from dangerous website link and it blocks malicious link, which makes our computer healthy.

I hope you will agree with me that antivirus program is better in case of security.

4# Privacy Protection

In the field of privacy protection Antivirus and Defender are all same in my view. They all provide us best performance. They all protect our computer from entering malicious link and all they protects our the internet connect with our laptop or desktop.

You can share your think that which is the better in the factor of privacy protect.

I hope your all doubts are cleared. One more thing you should know that Windows defender can enter our whole computer but Antivirus can’t. Defender can check our PC’s health and notify us if some issue is there.

What should we use (Antivirus or Windows Defender)?

This is the very important question can come to your mind. Now, I am going to clear this doubt. Before read this answer you should read “what is the Windows Defender”? so that you can understand this answer.

In some factor Antivirus plays good role like security, performance But in some factor like PC’s health checker, privacy protection, the Windows Defender is better.

I am using Antivirus in my laptop and my PC works so smoothly. So, in my experience I am telling you to use Antivirus. Don’t use both because you know that antivirus works inside in your computer, using the both Antivirus and Windows defender can be harmful for your PC’s processor and your PC can be slow.

One thing you need to know that any kind of PC protector program consumes energy from your PC and protector program effects on your PC.

I am strongly suggest you to use only one protector program for your PC. In my view Antivirus is best and If you want to use Antivirus total Security, it will be the perfect.

If you are using any windows computer then you should use Antivirus program. Sometimes Windows defender can’t protect your computer from strong virus.
