All the recent development concerning bitcion/altcoin are getting more and more suspicious, btc-e problem now people are complaining of blockchain after trying to forgot the mtgox matter.
Which way now?
What does this have to do with anything here?
I beg your pardon, Google translator. I wrote that I checked the computer virus is not found.
What I dont understand is how youc checked the computer for a virus.
I've been nothing to install, can install this software without my participation?
It depends on the system and the virus, but yes its possible for a virus to sneak into your system without you installing anything. E.g. via your browser while surfing.
As I understand it, I have to completely reinstall the system and then the problem would not be?
No, this will not change anything. If someone indeed stole your private key you have to use a different wallet. But first you should figure out how the attacker got your data in the first place. If your computer is indeed infected and you make a new wallet, it might not be safe.
Well transaction can not be stopped, but also can not block the thief?
No.
In any normal system that comes to money, if you suspect someone of fraud, block his purses and accounts, and that the time to return the owners. And then I look at his wallet flow Bitcoins, and no one to many this is not the case.
As vm1990 allready wrote bitcoin does not work like that. I am my own bitcoin bank. If I make a mistake there is noone else to go to. Your bank is blockchain.info, but once the information was stolen there is nothing they can do. The bitcoins are allready with the bank of the thief and the thief is most likely his own bank.
