Threat Description

Viral Code B


Category: Malware
Platform: W32
Aliases: Viral Code B, Viral Code F


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.


Automatic action

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

More scanning & removal options

More information on scanning or removal options is available in the documentation for your F-Secure security product on the Downloads section of our Home - Global site.

You may also refer to the Knowledge Base on the F-Secure Community site for more information.

Contact Support

Technical Details

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.
