When I visit the suggested link I have to go up one level manually to get to a
page that has a link to the actual source code. Norton Safe Web which is in my
router declares the link to the source code there at sf.net to be unsafe since
it has found one computer virus residing out there somewhere..

I don't know how real that concern is. Regardless, it may be better to point to
one level up to get to everything and one can scroll down the page to find the
link to CHECKSYS.

Just my thoughts.
