<b>Zenturi ProgramChecker ActiveX Control "NavigateUrl()"

I can't believe my eyes when I see what you can do with this ActiveX
(and I can't believe that this product is considered as antispyware).
You can use the "NavigateUrl()" to arbitrary launch local file
from a pc.
Try, for example, to launch "c:somefile.exe" and see what
happen.
Imagine to use this method with the "DownloadFile()" one, you
can download
something on the pc and run it without problems.
For the "DownloadFile()" vulnerability see:
