False Positive probably in Quarantined Items

Just started using MS SyncToy for incremental backup. Comodo AV has identified several files
and about 7 similar looking files as unclassified malware which are now sitting in quarantined items. They have been submitted to comodo. My search suggest these are temp files left over and not cleaned up by SyncToy. However- if they are needed by synctoy how will i know if they are safe and then be able to restore them from quarantine? There are only five options in quarantined items add remove clear restore submit but nothing to rescan the files to determine their legitimacy or otherwise? Or will my file submission receive a response?

I am reluctant to delete them in case they ■■■■■ up the backup of my data.
