The Filler virus uses the "extra track" method to hide the virus code, storing the rest of the virus code and the original boot sector on track 40. Its effects are not known, but it may affect programs in some way.
Note: If this virus is found only during memory scanning, you're probably just seeing a false positive caused by the Central Point Antivirus or Microsoft Antivirus. Remove CPAV or MSAV and try again.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
