Trojans are, by their nature un-repairable, they are new files. In order to be able to repair a file that is infected, it must be one that has been scanned by the VRDB process in order for a repair to be attempted.

You can move them to the chest and after investigation delete them. They can also be restored easilly if found to be ok. These however, don’t look like system files. A check on google would confirm or deny this (this is what I mean by investigate).

A boot scan you be your best option (disable system restore first otherwise it will end up there after deletion), so these trojans are not protected by windows.
