Is possible innestate a kind of virus in a blockchain? Example if these virus exist on evry pc in the world after some pc became a node for blockchain, is possible turn it on that virus and cerrect the blockchain in any world pc, or in a lot of them?

As I know it's impossible because data is blocked. That's why the technology is called so. Also if one of the blocks will contain additional data with virus, other blocks will detect that. Of course, hackers may be working on viruses for blockchain, but for now as I know there are no threats.

You also have to take into consideration that you're only asking about miners. Most, if not all, of the miners are in pools and the pools are, more often than not, in large industrial mining facilities, for Bitcoin. So to have an attack, virus, on a miner you could, theoretically, take down an asic or two before the staff at these facilities figure out what's going on. But you won't take down the whole pool. Once they do, they'll get new asics and get rid of the infected ones. As for Bitcoins themselves, I don't see a virus infecting a Bitcoin and then distributing among the populace. But I could be wrong there. :-\

I hope it will not exist, this will be a big disaster and I'm sure Bitcoin will be ruined.
remember the case of ransomeware, bitcoin holders will feel panic and cause prices to fall.
I still believe this is hard to do.

Viruses on a blockchain is technically impossible with current tech.

Let’s hope it never happens though.

I agree with this idea. However, with technology development, nothing is impossible. I still hope that does not happen.
