what role does blockchain play in all this, isn't it easier to use traditional methods of fighting viruses?
My friend, blockchain plays a key role here, because only these technologies can guarantee real security.
True. Without blockchain it will not be possible and secure to move money from fools to anon Evil Dev, Hackerd, CyberHacker and Don Mafiosi team. Without blockchain they can easy go to jail. But it's possible to use blockchain to securely and anonymously sell all 100% premined coins to fools before exit scam. And you are not in the jail because of key role of blockchain, but have own island.
