Are there good (and preferrably free) vulnerability scanners for Windows?
Please don't suggest update checkers - I know about Secunia PSI, FileHippo and CNET checker.
Secunia PSI 1.5 used to do exactly what I need, but in latest version it regressed to a mere update checker, and would not report vulnerability unless there is a patch for it (browser extensions show up in secure browsing page, but vulnerabilities of other applications are not shown at all if there is no patch yet). That is not want I need - I would like to know about a problem even if there is no solution yet, so I would avoid using the program, uninstall it, apply workaround, etc.
Is there anything comparable to old PSI?
