F-Secure anti-virus products do not detect any viruses by these names. However, these viruses are sometimes reported because CPAV (Central Point Anti-Virus) uses these names.
Disinfection & Removal
Allow F-Secure Anti-Virus to disinfect the relevant files.
For more general information on disinfection, please see Removal Instructions.
When the heuristic scanner of CPAV thinks it might have found a virus from a boot sector, it calls it 'Viral Code B'. If the suspicous code is found from a file, it's called 'Viral Code F'.
This doesn't necessarily mean the files or boot sectors are actually infected, they might just contain suspicous code. In any case, you should have the files or boot sectors checked to make sure whether it's a false alarm from CPAV or a real virus.
