After reading the last post from "TrusteerSupport", I would be more than wary regarding the use of that "software".
There's a simple reason. When you "uninstall" it, why does it leave ANYTHING? After all, if you are getting rid of that programme you will want EVERYTHING deleted, you want no reference to the programme what you are getting rid of. There should be no "profiles", there should be no "legacy" files or registry entries. You "uninstall" and everything goes. Period. Otherwise you are just as bad as Symantec.
My bank over here doesn't use something that, in my mind, is malware. If the Trusteer people can tell us why their software does not wipe out EVERYTHING when you uninstall it, I would think we would all like to know.
After all, it is, at least, piss poor programming. And if they cannot get that right then why should anyone trust the chances that their software is actually "secure"........................
