Release 2, April 1990, used a CRC-32 signature and one based on CRC-32 but with a few bits in each word shuffled. Doubling the signatures rendered useless, or at least immoderately difficult, attacks based on CRC invariant modifications. The original Quarantine used Hunt's B-tree database of files with both their CRC16 and CRC-CCITT signatures. Released in April, 1989, Quarantine was the first such product to use file signature instead of viral signature methods. In December, 1988, shortly after the Morris Worm, work started on Quarantine, an anti-malware and file reliability product. Files put in quarantine were then no longer capable of infecting their hosting system. Quarantine was an antivirus software from the early 90s that automatically isolated infected files on a computer's hard disk. ( Learn how and when to remove this template message)
