I noticed that my Win Vista Quad received an error message that it had hit it's daily quota limit. After investigating, I realized that it had been having nothing but error WUs.

After further investigation, I finally saw a Norton SONAR notification that it had quarantined the WUProp workunit, even though I have the BOINC Data directory excluded from Norton scans.

The updated version of Norton SONAR ignores your exclusions and automatically quarantines the WU. The only way to repair this is to go into the Norton Security history and restore the file. Make sure you check the box "Exclude this risk from future scans".

This seems to have fixed the problem for now.
