I’ve Not Used a Third Party Antivirus in a Year Thanks to Windows Defender


Eset Antivirus

I’ve not used an antivirus on my laptop for a year now and that is a big deal.

Windows PCs have always been plagued by malware of all types. The fear of your PC getting infected by viruses has always been real. Your PC could get infected from clicking on suspicious links, downloading suspicious files from the Internet or worse, getting infected from removable media like flash drives.

The huge malware problem in Windows created an entire industry of antivirus products being sold to users worldwide. Having an antivirus became a must and you’d see people buy antivirus programs like Kaspersky, buy laptops with pre-installed antivirus software like Norton or McAfee or get free ones like Avast.

Also during that time, Microsoft had its own antivirus program called Windows Defender. We didn’t pay much attention to it because it was not as thorough as the third party ones, and this changed when we switched to Windows 10.

I had two main gripes with third party software:

  • They were resource hogs. This was apparent especially when you used low powered laptops. Back then I had a Samsung netbook that ran the lowly Intel Atom processor and only 1GB RAM. Kaspersky antivirus used to gobble like 40% of my CPU power and quite a huge chunk of my RAM while scanning for viruses.
  • They were not native. You had to either buy them or get a free version and the free ones were not so good. Native apps are usually optimized well and you don’t have to pay for it (usually) and Windows Defender was not good at the time.

Enter Windows 10, which was announced as a free upgrade in 2015. When we initially upgraded, Windows Defender seemed to be unchanged so we continued using antivirus programs as usual. However, with every subsequent major update to Windows 10 (November Update, Anniversary Update), there was a minimal change to Windows Defender.

That changed with the March 2017 Creators Update where Microsoft overhauled Windows Defender by introducing the Windows Defender Security Centre. This overhaul plus the apparent refusal of Windows not recognizing my antivirus meant that I was stuck with it and I just decided to try it out.

From March 2017 to October 2017, I had no issues with it. Windows Defender did not use my resources as heavily as my third party client and was able to clean out effectively suspicious files that I had on my laptop. Windows Defender became even better during the Fall Creators Update where they added even more features to its arsenal and I never once thought of going back to installing a third party app ever again.

If you check out Windows Defender, you will notice it is a fully fledged antivirus that is native to the OS. It does both antivirus related tasks as well as checking out your PC’s health (storage capacity, battery life, apps) which I find quite weird.

Windows Defender antivirus functions extend from the usual scanning as well as having real time protection, cloud delivered protection and automatic sample submission and controlled folder access so as to prevent unauthorized changes by rogue apps. You can even exclude certain items from being scanned. It also has ransomware protection which will protect you from your laptop being taken over for money.

It is surprising that I’ve managed to stay without needing to install a third party antivirus since the March 2017 Creators Update and it attests to how effective Windows Defender has been over the past 16 months. It is even more surprising that Microsoft didn’t do this sooner while on Windows 7, but as they say ‘better late than never.’ I don’t think I’ll change this setup going forward and Windows Defender has the opportunity to become even better in the future.

  1. I haven’t used an anti-virus since 2012. That was the last time I relied on one. But I hear kama wewe si mtu wa darkweb then an AV is not a necessary software.

      • Yeah. Security starts with you. Haha. I made sure no external drives are plugged on my PCs and I have never experienced any issue with viruses. At that time Kaspersky was my favorite. ESET used to drag my PC so much. Actually, I used it in 2010 and ditched it a few months later.
