The INTC virus is a simple 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 INTC infects
the Main Boot Record, and after that it will go resident to
memory during every boot-up from the hard disk.
Once INTC gets resident to memory, it will infect practicly all
non-writeprotected diskettes used in the machine. INTC installs
to interrupt vector table, so it does not decrease the amount of
available memory, but can cause compatibility problems.
INTC was reported to be in the wild in USA in December 1996
and in Finland in January 1997.
