prl_naptd annoyance after upgrade to build 9376

Hello,

After upgrading to build 9376 (argh... why did I do it?) Mac OS displays an annoying message when I start Windows XP VM, asking to allow or deny prl_naptd to listen for incoming connections on the network.
(prl_naptd is listed in the firewall settings to listen for incoming connections.)

I found an earlier post regarding this issue, but with no other solution than the suggestion to reinstall Parallels.

I removed Parallels, but I did not remove the Parallel Application Settings. And I reinstalled. No success, the prl_naptd message still shows up.

Before I give it another try, also removing the Parallel Application Settings, I'd like to know if anyone knows of a solution that actually is confirmed to work (and is easy and takes only little time).
