Sunbelt Personal Firewall 4.6.18xx was in use for a long time on this pc. We decided to remove this firewall because it led intensively to BSODs. Sunbelt Firewall Cleaner had been applied. After firewall removal the Vista Device Manager still shows two items of Sunbelt NDIS Filter IM Miniport device. One called #3, the other one #6. It is not possible to remove these device manually, neither by unsinstall, nor by uninstall along whith driver files removal. These two devices keep always to be listed in Network Adapters group. Registry shows several items related to these two devices. HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\0015 There are more than two items of #3 and #6 miniport device under ControlSet002. Also other registry branches still refer to these devices. How to remove these two devices properly?
