One item remains unprotected.

On my XP/SP3/AVG desktop Spywareblaster has been updated to latest version and continues to update as it should enabling protection on all items,
...however .....
On my laptop running Vista Home Premium/Kaspersky AV,since the upgrade to the latest version, I am getting,under restricted sites, "one item has protection disabled"
Scanning through the block list I discover:
Coolwebsearch(281) ...... document-not-found pornpic.org
in red and with the box unchecked. If I check the box and re-enable protection it unchecks itself again.

I have also discovered that if I disable and re-enable all protection then it shows as "all items are protected" but if I then close down the GUI and reopen it the "one item unprotected "returns.

Could this just be an issue with the latest database/a conflict with Vista as it does not occur on the XP machine/ or should I be lookng elsewhere?

 

FYI ...I appear to have solved the issue
Having traced the offending registry entry ( HKEY Current User/software/microsoft/current version/internet settings/zone map/domains) - it was the only one in the database to have a sub-folder (document-not found).
Resetting permissions in safe mode I have deleted this sub-folder and the item in the Spywaeblaster block list will now accept a check mark and all items are now shown as being protected.
I have no idea why,of all the items which Spywareblaster adds to the above registry location, this one alone should have acquired a sub-folder.
