      You may be trusting their NDAs, but it's still a hot target that will be scoured for vulnerabilities.

      So you win in NDA land but may lose in defense in depth.

      My favorite AV is a locked down, white-listed AppLocker policy :)

      Me too. I wish application whitelisting and baselining were feasible for home users.

      Unfortunately, you're giving them pandora's box complete with a key and warning fatigue.

      We're back to warning fatigue, and the fact that most users will see it as an impediment and focus on bypassing permanently.

      We are way off-topic, but iOS is an example of widely deployed whitelisting for avg users and nobody sees it as an impediment. It can work.

      Imagine how polished the experience would be If we spent 1/2 the resources we spent on blacklisting on whitelisting 😛

      would that be the whitelisting that already exists in many AV products, or the whitelisting that deals with orders of magnitude more ...

      I've looked at a lot of Antivirus code. I know what's actually shipping, and it ain't whitelisting.

          perhaps you have too narrow an idea of what constitutes whitelisting. symantec's reputation engine is part whitelist, for example

          Perhaps your definition is just wide enough to include whatever Antivirus vendors happen to be shipping? ;)

          Windows *listing feature is AppLocker. Lots of other 3rd party white listing products around, but more hassle than AV, so less popular
