I practice safe surfing, but you can’t dodge every bullet. There is a new trojan out, confirmed here (http://forums.wow-europe.com/thread.html?topicId=12730404058&sid=1&pageNo=1#15), that is allowing hackers access to accounts protected by a Vasco Digipass Go 6 authenticator. This is a 6 digit numeric one-time passkey device.
I have not been infected myself (as of yet), but I have not seen any indication that Avast protects against this threat. I thought it best to get the info out there.
