I really do wish Alwil would get rid of this All Chest Files collation of the three sections.
- The only area you should be interested in is the Infected Files section, this is where the files detected by avast and selected by you to move to the chest are placed. So there is nothing to fix.
- The User Files section is where the user can add files they suspect of being malware but not detected by avast.
- The System Files section is where avast keeps back-up copies of important system files in case the original becomes infected (leave them alone).

Trojans generally can't be repaired (either by the VRDB or avast virus cleaner), 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.
The VRDB only protects certain files, mainly .exe files, it doesn't protect data files or all files, it is not a back-up program, so there are going to be many occasions where repair won't be an option.
Only true virus infection can be repaired, e.g. when a virus infects a file it adds a small part to it, provided that file is one that avast's VRDB would monitor and you have run the VRDB, 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.

If they are in quarantine, either SAS or the avast Chest then there is nothing further to do they can do no harm there. There is no rush to delete anything from the chest, a protected area where it can do no harm. Anything that you send to the chest you should leave there for a few weeks. If after that time you have suffered no adverse effects from moving these to the chest, scan them again (inside the chest) and if they are still detected as viruses, delete them.
