I tryed to uninstall BD and immediatly upon starting the process I lost Internet connection. I had some problems during uninstall and completed it using BD uninstall tool.
After uninstalling there are some exclamation marks in Device Manager (Win XP):
Network Adapters
1394 Net Adapter (without exclamation mark)
BitDefender Firewall NDIS Filter Miniport (exclamation mark)
Realtek PCIe GBE Family Controller (without exclamation mark)
Realtek PCIe GBE Family Controller - BitDefender Firewall NDIS Filter Miniport (exclamation mark)
WAN Miniport (IP) - BitDefender Firewall NDIS Filter Miniport (exclamation mark)
Should I uninstall all of them and reinstall or there are some other steps I should be aware of?
Searching about this kind of problem I found that it can get really complicated.
