Second opinion if these should be deleted.WinSxS always worries me.
Used Revo and AVG Clear.They never get everything.I will update my clean copy of Windows 10 and back up before I try anything.They will be safe to delete, but I recommend you run AVG Clear instead. It is AVG's own tool for removing leftovers.
I will do a backup before I delete anything.I also updated my Windows 10 installation media.I've deleted such entries using the same Everything app after uninstalling an AV without any problems but never did so for AVG. But first make sure those are all related to AVG only then at least create a system restore point and delete those entries.
