The INTCE virus is a diskette and Master Boot Record infector. It is
only able to infect a hard disk when you try to boot the machine from
an infected diskette. At this time INT_CE infects the Main Boot Record,
and after that it will go resident to memory during every boot-up from
the hard disk.
Once INT_CE gets resident to memory, it will infect practicly all
non-writeprotected diskettes used in the machine. It uses interrupt
CEh, hence the name.
INT_CE modifies the partition data so that the machine is not able to
boot from a floppy any more - only from the hard drive. To boot such
a machine, use an IBM PC-DOS 7.x floppy or MS-DOS 3.3 floppy.
It can also cause compatibility problems. It can cause a machine fail
