Sorry there is zero information about these other two files, name, location, malware name and what type of scan detected them. Without that no one can say why this is or might be. Not all files can be repaired.

Trojans generally can't be repaired, because the entire content of the file is malware, so it is either move to chest or delete, move to the chest being the best option (first do no harm). When a file is in the chest it can't do any harm and you can investigate the infected warning.
Only true virus infection can be repaired, e.g. when a virus infects a file it adds a small part to it, then it may be possible to repair the file to its uninfected state.
However, for the most part so called viruses, trojans (adware/spyware/malware, etc.) can't be repaired because the complete content of the file is malicious.
