Joshi is reported to have originated in India. It infects the partition
boot sector of hard disks, storing the original, as well as the rest of
the virus code elsewhere on track 0, head 0. Just like the Brain virus,
Joshi redirects attempts to read the virus code while it is active in
memory.
The virus activates on January 5th of any year and displays the message:
type Happy Birthday Joshi
Unless the user obeys and types "Happy Birthday Joshi", the system will
hang.
