A virus targeted several computers at the City of Bellevue last week, and it took seven Sarpy County information systems technicians two days to fix the problem.
The city was targeted on Halloween by a new kind of virus called CryptoLocker Ransomware.
This virus encrypts the target's files. The attacker then contacts the victim and asks for money in exchange for the encryption key.
However, in this case, the technicians fixed the problem before the attackers could solicit a ransom.
It had affected seven city computers.
Mark Walters, the county's information systems director, said he's not sure how the virus got into city computers.
It appears to have come through the police department, though, and it affected a police server.
The city's files have been restored from backups.
