Hi Carol:
Sorry your scans are still dirty, but just to make sure, try this:
1. Close Spybot and open Firefox
2. In Firefox, open "Bookmarks" and select "Organize Bookmarks"
3. In the right hand panel, right click the narrow bar at the top and make sure "Location" is checked
4. In the left panel, under "Bookmarks Menu" select each bookmark (or folder) one at a time, and check its location for "spywareinfo.com"
5. Each time it shows up, delete it....this is in case you have multiple bookmarks pointing to the offending domain
6. When you're finished, close Firefox, cross your fingers, run a Spybot scan, and pray for a "same ole" boring clean scan
