After recieving, for the umpteenth time, a link from a friends compromised messenger account that directed me to a messenger password stealing/trojan downloding site an idea popped into my head.
I tend to report these site, when they're spammed to me, into IE, Firefox and Opera's Phishing/Malware filters (well FF only has phishing...) and I've noticed that a good number of times IE or Firefox (Opera less so, smaller userbase perhaps?) block accesss to these site as they've already been reported.
Hence I think the propagation of this crap would be greatly reduced if messenger passed all URLs sent through its SmartScreen Phising/Malware filter; removing those that were detected, replacing them with a message to that effect.
(I've already submitted this as feedback to the WLM team via the feedback link on the Windows Live site, I just wanted other people's opinion on the idea)
