What is it in the chest, file name and original location, malware name and which section of the Chest is it in ?
Repair would only be offered (on detection) if it is possible to attempt it, this depends on the malware type if it was a file covered by the VRDB generation, etc. so the above question is important.
I don't know what you read (?), but Restoring a file considered infected is ill advised.
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.
