I don't use Virtualbox, but apparently when I used a portable Virtualbox, it left behind drivers. I learned this because I have decided to ditch an AV and use Online Armor Free with AppGuard. It warned me it is not compatible with Virtualbox's Bridged Network Adapter driver and that it would cause BSODs. I manually deleted the drivers and their registry entries. OA installed, but I am wondering if this conflict will be resolved in the future?
