Brain.exe can help prevent Malware Infection and no system is 100% secure. Making changes again and again... After a new install of Windows 10 I noticed something... The default solution by Microsoft is good when no AV was previously installed. Impact is like non existant! Dont get it why?! Software and other things are selected beforehand and installed after updates Windows 10 were applyed. So strange things with Windows 10 and AV solutions. ^^ Best regards Val.
