Hippie virus is a typical boot sector and MBR infector. The virus does not fit in to the boot sector alone, so it takes allocates three additional sectors. All of the sectors are encrypted.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
The virus is harmless, but has stealth features. You have to boot from a clean floppy to disinfect it. Hippie does not decrease the amount of available memory.
The author of Hippie is "Dr. White", who has written the Junkie and Desperado viruses as well.
