ESET Password Unlocker

I accidentally found this online, I tested myself on a test setup (ESS 6 / Windows 7 x86) and it actually works, it took only 2 seconds.

Shouldn't something be done against this as it renders ESET protection useless if the computer was left unattended and a person with malicious intentions got hold of it for couple of minutes?

What really annoys me is not that such a tool exists, but the fact that ESET is aware of it (NOD/ESS can detect it as "Win32/RiskWare.HackAV.JJ") but did not solve the core problem, since the tool can still be run from another computer and get the job done.

Although I think it's unnecessary - for the aforementioned reason - but I'll PM the tool to a moderator if requested.
