Spyware blocks software backup

Just added Norton antivirus 2009.  I have been running Davis Weatherlink software for the past few years on my XP machine.  I was running a Corp sponsored version of Norton with no problems.  Since adding Norton 2009 I get an error message saying a "backup file could not be uploaded".  The error does not appear if I turn of the AnitSpyWare function.

 

Can someone help?

 

Thanks

Doug
