ask: and if one of us was infected with ransomware and he sent data to the creator of the trojancrypt, as with spyware and keyloggers, would he be protected?
I let bitdefender free for over 3 years with my familly PC... Before that, i had to clean it all the time it got infected. After Bitdefender, nevermore.
The only cons is that it has more performance impact than kaspersky
