"GenB" is short for "generic boot sector infector" and "GenP" for "generic partition sector infector". There are no such viruses at all. These are simply a "shorthand" that McAfee SCAN uses to tell you that it is sure there is something suspicious in your diskette's boot sector (GenB) or your hard disk's MBR (GenP) but it doesn't know precisely what.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Detailed instructions for F-Secure security products are available in the documentation found in the Downloads section of our Home - Global site.
