Putrid
Description Putrid
It is a dangerous memory resident boot virus. It hooks INT 13h and infects the MBR of the hard drive and boot sector of floppy disks. The virus contains the text string:
>PUTRID<
Depending on its counter the virus also hooks INT 21h. While executing a file the virus searches a disk boot sector image within this file - the virus scans the file for the "MSDOS" string and checks boot stamp 55AAh. If such data are found, the virus replaces them with its copy. As a result, the virus converts disk formatting utilities to virus droppers - while formatting a disk they will write to the disk boot sector the virus code instead of original bootstrap routine.
