I use Kaspersky AV, but the best is Brain.exe
Since Years i have no Virus or Malware on my PC and i use the PC daily. I have an Adblocker that will kill the most way for Malware and i not click on Bling Bling Images or whatever what i will not see. And Fake Mails is very easy to recognize.
So i have no Problems with Virus, Malware or another fake Shit.
