Which virus protection do you use for your computer, laptop?
You don't need more, paid antivirus programs are history
Under Windows 10 I use Windows Defender and under Windows 8.1 I use Avira. However, Avira annoys me more and more. It may also fly down there in the long run.
A combination of windows defender and sane mind 1.0 das, the successor software of brain 1.0
Brain.exe. Or Linux. I think both are solid choices to protect against viruses.
I use Kaspersky, I'm totally satisfied with it, especially the live protection is really good. Although I use the function of the actual antivirus rather less, as I rarely come across something like that, I still like to use the password manager and other small features.
