Solvusoft / WinThruster - download deleted by Norton 360

Hello,

I purchased WinThruster (and WinSweeper) from Solvusoft back in July. A month ago my WinThruster was not working properly so I contacted Solvusoft who provided me a link to download it again.  Once the WinThruster download is finished , Norton File Insight informs me that it has removed it as it is considered 'a threat  -- RegCleanPro'  (see below data copied from Norton File Insight clipboard).

For the three months that it was working properly , I thought it was doing a good job. So unsure why Norton considered this application as a threat ? I also do not understand how WinThruster and RegCleanPro could be related?

Do you think it is ok for me to restore the file and have it in my computer?

Thanks!

Phoebe.
