This might cause a machine to become unbootable. Do not use these versions of F-PROT to disinfect this virus. Contact support instead. The Ripper virus was found in November 1993 from Norway. However, it is believed to be of Bulgarian origin.
Ripper infects floppy boot records and hard disk master boot records.
The virus will only infect hard drives when an attempt to boot from an infected diskette is made. Once the virus has infected the hard drive, all non-protected floppies used in the machine will be infected. Ripper virus is two sectors long, and it stores the original boot sector to the last sector of the root directory, and also reserves one sector before that for its own code. The virus is encrypted with a variable key. Encryption is quite rare among boot sector viruses.
