"Bonjour" and Winsock 2 and Internet connection

"Bonjour" (which is installed without permission - it is a Mac product but can be installed on XP) was unsuccessfully installed on my computer.  When I run a Windows Registry cleaner (Registry First Aid), it detects several Registry entries related to "bonjour" as follows:

If I go ahead & delete these entries, I am then unable to (1) access the internet and (2) unable to reboot back into Windows XP.  In that case, I need to reboot in Safe Mode & execute the RFA backup file to restore the Registry entries which were deleted.  Then all is OK.  

I could just tell RFA to ignore these Registry "errors" but their presence "disturbs" me.  Can anyone shed any light on this & tell me how I can clean up this mess (like, why is this happening)?  Thanks.
