I respect everyone's opinion. If someone believes products from one company are better than using multiple tools from multiple vendors is better, great! I just haven't experienced the same throughout the years in this tech world.
I used to be huge Avast fan and avid hater of Microsoft Security Essentials/Windows Defender back in the days. And truth to be told, it did suck back then with pretty much every other antivirus offering a better protection. My views started to change when Avast started converting their products from antivirus to adware (possibly spyware); same happened with other companies.
I remember stuffing my PC with so many security tools you couldn't count them on fingers of two hands. Then I realized: "
wait... all of this just wastes resources, let's see how many times each tool activated and provided me protection". The answer for all of them was—not even once. I started to remove one by one to see if I could surf without getting infected and I passed the test. Not only did I realize how slow my PC was because of these security tools, but it also turned out that reading all the security (dis)information in media only made me paranoid and insecure.
I hope every single one of you will enlightenment as I did.
