I uninstall my antivirus a long time ago and I think the windows defender is really the best antivirus that would work to every windows computer.
It's the best decision I've ever made on my computer to uninstall the antivirus and its feels like the computer is really more secured and also a lot faster, I honestly think that antivirus is just eating your computer memory.
Antivirus that only takes up your memory is an antivirus that may not be recommended or your memory is too small in capacity. Double protection will keep the device safer. I have experienced a horrific event where I only used Windows Defender and accidentally installed Ranshomware which then made Windows Defender Off Protection. Ransomware causes my data to be encrypted and cannot be restored like all. There must be a ransom that I must give to be able to get my files back, but I did not do it, because of the high ransom they requested.
that's my reason why it's better to use additional Antivirus. Malwarebyte or other recommended antivirus will be my savior.
Your security is your own responsibility. Everyone has their ways to make it safer.
