Implant is a polymorphic multipartite virus. It infects COM, EXE and SYS files as well as floppy boot sectors and the hard disk MBR.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
In files the virus is polymorphic. It has a double layer encryption which makes the detection and the disinfection more difficult. The virus is not polymorphic in boot sectors.
Implant makes it impossible to boot from a typical boot diskette: it uses the circular extended partion technique. It is possible to boot the infected PC only from a clean MS-DOS 3.x, 4.x or PC DOS 7.x system diskette. Most common boot floppies with MS-DOS 5.x, 6.x or 7.x (Win95) will simply crash during the boot-up.
Since the virus is full stealth everything looks clean when the virus is resident. It will not infect many files, based on their names. Also, the virus will not start spreading immediatly after it has been run, it waits up to an hour - apparently to fool antivirus researchers who are trying to replicate it.
Implant activates on the 4th of June. At this date it attempts to overwrite the boot sector of the hard drive and shows this message on screen:
