DoomMbr.406
It is not a dangerous memory resident multipartite virus. It contains the text: "DOOM". It infects the MBR of the hard drive, boot sector on floppy disks, COM and EXE files. When an infected file is executed the virus infects the MBR of the hard drive and returns to the host program. While loading from infected disk the virus hooks INT 13h, waits for DOS loading process and hooks INT 21h. The virus then overwrites boot sector on floppy disks that are accessed. It also writes itself to the end of COM and EXE files when data&time stamp for these files is set (while copying to new files, for example). |
