FLORENCE, Ariz. - The Pinal County Attorney's Office announced Tuesday that it had recovered thousands of case files that had been corrupted by a ransom virus.

A release from the office said that one laptop and 64,000 case files had been affected, and the IT department fixed the issue using a backup server -- they did not pay any money to un-encrypt the files.

"Due to the county's inadequate anti-virus software, our office's case files became the target of a virus," county attorney Lando Voyles said in the release. "Luckily, it did not take long for our IT department to restore all 64,000 files. It remains frustrating as they still wasted time on this tedious task."

The county is now researching new anti-virus software.
