The message reads KMODE EXCEPTION NOT HANDLED ndis.sys
The minidump pointed the Virtualbox (VBoxNetLwf.sys). But after upgrading Virtualbox and eventually deinstalling the problem remains, but now pointing to npcap.sys.
I reinstalled Bitdefender VPN, but that did not help.
At first installation of Bitdefender 2 weeks ago it worked fine.
Any suggestions?
