protect users from victimisation by the likes of this : http://www.bleepingcomputer.com/forums/topic204619.html For years (decades?) I've been DNS hijacking to criple worm ridden machines associating with my wifi nodes etc. That only deals with a few threats. I'd like to feel confident in using blackhole routes to combat maleware proliferation too. Any tools available to age out male-routes after a given period of time?
