I was able to retrieve the file you uploaded to virustotal from the link in the avast forum. This is a false positive detection on Superantispywares part. Notice on virustotal they are the only one to detect it out of 40+ av companies? This is a legit component of realplayer. If you right click the file and hit properties it has a valid signature signed by realnetworks.
There is a realcleaner rogue but its not in this location ever.
This is where the realcleaner rogue is located:
C:\Program Files\realcleaner\realcleaner.exe
This is where the legit realcleaner is located:
C:\Program Files(x86)\Real\RealPlayer\RealCleaner.EXE.
