Here’s the support response I got from Intego support yesterday:
Thank you for your request.
We are getting quite a few Support Tickets about this detection. Paddle has been identified as a potential false positive alert.
Several customers have already submitted the file to us and we have confirmed they are false positive alerts.
We have updated our Malware Definitions so after the next update these files will no longer get detected. We will likely release the Malware Definition update on Thursday.
Until then you can Trust the Paddle file to prevent VirusBarrier from detecting it as an infection.
Since you have selected to repair the file, VirusBarrier has stripped code from it which has caused the Rapidweaver program to crash, apparently.
To get Rapidweaver 7 to start working correctly again please try restarting your Mac. If the program is still not working you may need to reinstall the program again.
Please let us know if you have any other questions.
