I have been using Look N Stop for 3 years now and been a very happy camper. DrWeb and I became software friends about 11/2 years ago. Both are terrific programs but it seems that occasionally when I open DrWebs scanner it will find SQL Slammer and remove it. This ends up killing the firewall. I have tried adding the Look N Stop driver to DrWebs exclude list which seems to help reduce these hits a bit but they still occasionally happen. Any suggestions out there?. Maybe shut down the firewall for a minute before opening the scanner?. Whatever it is it seems to be memory resident.
