There are so many Suspicious and dangerous virus, malware and spyware infections. Especially Trojans, Rootkits which are the deadliest among PC infections.

In order to protect from these harmful infections, you need to have a Antivirus which is so Strong enough to Protect your PC all time.


Avast antivirus was launched in the year 1988. Its a pretty old antivirus which is been there in the system protection field for a very longtime.

Since they are in the industry for a very longtime, they know the In and Out of Infections and how they infect the PC. Avast not only protects the PC, But also does a root level scan in the BIOS as well. There are some virus infections which will lock down the BIOS settings as well.

So when it comes to root level scan, I would suggest you use Avast… It also helps in preventing annoying Notifications from appearing when playing games. It also protects your WiFi being hacked.

Avast is good but the only Sad part is, Most of the Users are complaining it works in PC background and reduces the PC performance drastically like a Tortoise.

And also there are certain complaints which is reported by Microsoft, Because of Avast Antivirus doesn’t comply with Microsoft Latest 1803 Update, Most of the PC’s are getting crashed and never boots to desktop screen. Because of which most of the users are unhappy with Avast.

But when checked with Avast, there are No complaints regarding this it. Hope Avast and Microsoft come into One conclusion to get this confusion sorted out.

AVG is founded in the year 1992 and there are more than 200 million active users worldwide. When i was in my child-hood the First antivirus program which i saw in my Friends PC is AVG. I have asked my friend why you are using this Antivirus, he said is a FREE version and this the Cheapest Antivirus which he can afford and it works best in XP SP3.

From that On-wards, I have used AVG for a while, And it auto-detects virus and Malware infections from PC and removes Instantly.

And for people who are using Traffic generating software like Traffic Spirit, Jingling or any other Bots be aware this AVG antivirus will remove it and it will think it is a Virus or Malware due to it Activity behaviour.

The Only Sad thing about AVG is, It is working fine, But it will never gives an option for the Users to Double check and Confirm whether the application which is reported as Threat is Actually a Virus or Malware. So that we can Safe guard the application from getting removed.

AVG has Browser extensions, We can also protect mobile devices as well. It also have FREE VPN for limited period.

Microsoft Windows Defender:

Microsoft Windows defender  came into picture as General availability On October 24, 2006. At first, Microsoft launched this antivirus program as FREE for all users with the Windows Operating System.

It was also available with old version of Windows platform, Later on they have keep on improvising its performance and its defects and upgraded there Antivirus program.

The Best thing about Windows Defender is, It is completely free and Full Version Antivirus program. Yes, What is said it right. Instead of bugging its users to buy Antivirus program as per Microsoft OS requirement. They have released there own antivirus so that customer’s don’t have rely on other Antivirus vendors.

You may come across so many Antivirus program not working properly with Windows because they may have some defeats because of future updates from Microsoft.

But Windows defender will not have this issue, since its a built in program working with Windows itself. So if any future updates are being deployed. It will not affect the PC performance or antivirus performance.

Windows Defender has lot more features like Parental control, Find my Device, App & Browser Control etc.

Even though it has So many Positives but it has some Negatives as well.

Windows defender is only available for Windows PC’s and its not available for MAC or Android or IOS.

If you have Multiple devices and you need Multiple Protection, Then this Antivirus program is not the Right choice for you. But you are a User with One PC and don’t want to pay for any antivirus program, then you can very well use Windows Defender.


Final Conclusion:

From the above antivirus review, I have One Antivirus program which works best at all times for all devices.  Even-though there are some controversy behind this antivirus program regarding some flaws, But according to my Knowledge… It is working absolutely fine without any hassle. Its none other than Avast Antivirus. Is the Most renowned and Best Antivirus among the Rest.

Except Avast no other Antivirus does Root Level Scan to Protect your PC.
