Technical Details


It is not a dangerous memory resident multipartite virus. It infects
EXE-files, the MBR of the hard drive and boot sector of 1.2Mb floppy disks.
It hooks INT 13h, 21h and copies its TSR code to high memory area (HMA).
While infecting EXE files the virus creates and writes itself to
companion COM files. When such file is executed on non-infected PC,
the virus beeps and infects the hard drive MBR.
