Bank of America recommended me of installing something called Rapport from Trusteer.com, see their website. Of course I don't trust these random security software. Especially if it seems to install a plug-in into the OS/browser which purportedly protect us!
I wonder if there's any info available how it works. Does it inject code into Safari/Firefox/Chrome? If so, how? Does it do via supported means (Safari/Firefox/Chrome extensions), or does it use mach_inject, say?
