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 detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
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 to boot.
