This virus may be related to the 'Klaeren' virus - at least it contains the same "bug", which prevents it from successfully infecting any file larger than around 4000 bytes. Longer infected files should be discarded, as they are probably unusable.
Disinfection & Removal
Allow F-Secure Anti-Virus to disinfect the relevant files.
