I believe you have found your problem, even when switched off resident antivirus and firewalls, will have low level drivers still running and it is these which come into conflict.
It needs to be completely uninstalled. You didn’t say what it is, but uninstall from Control Panel, Programs & Features.
Depending on which program it was you may need to use its removal tool to ensure no remnants are left. Also see http://thewebatom.net/uninstallers/security-software/, this has a collection of manufactures removal tools, so that should remove any remnants, registry, etc.
