I run Webroot/Prevx Secure Everywhere Beta along with NIS 2012.
It has identified this file as being suspicious as a ws generic Trojan:
c:\programdata\norton\{0c55c096-0f1d-4f28-aaa2-85ef591126e7}\nis_19.1.0.28\definitions\bashdefs\20110929.001\bhengine.dll
Is this file OK and if it is what about this file might have triggered it as looking suspicios?
