What i have been told is that bitdefender / kaspersky has best signatures
But bitdefender on vt has not detected ransomware by signatures = fail on the video
Bitdefender has behaviour blocker, but its too late when files are already enrycpted?
Doesnt mean bitdefender is bad, it just doesnt have any zeroday protection on free version and needs help by other sws
On other hand i have no idea how common these zeroday infections are in real life situations, its not bitdefenders fault if someone ran suspicios file , probably the web filter already did job before that and adblocker blocked it coming from ads, idk
People that torrent will run any file, even they get prompted by av/ security software
