If the scan comes up with unknown ones and you dont know what they are/do (do some research, google) leave em...for the rest, well it says "safe"and "not fully safe", i always let it clean out those 2 sorts and never experienced any problems.
If you still doubt, make a restore point before doing anything (regcleaner creates backups too tho...but you know better safe than sorry).
The one you mentioned in your first post was still there too, right mwe99?
