Disinfectant was a popular antivirus software program for the classic Mac OS. It was originally released as freeware by John Norstad in the spring of 1989.^[3] Disinfectant featured a system extension that would detect virus infections and an application with which users could scan for and remove viruses.^[4] New versions of Disinfectant were subsequently released to detect additional viruses.^[4] Bob LeVitus praised and recommended Disinfectant in 1992.^[5] In May 1998, Norstad retired Disinfectant, citing the new danger posed by macro viruses, which Disinfectant did not detect, and the inability of a single individual to maintain a program that caught all of them.^{[3] [6]}
