Before you download

I found a resource online that everyone else has probably known about for years, but oh well.  McAfee Site Advisor lets you plug in a website and lets you know if that site has an iffy record, if it connects to sites with lots of spyware, which websites it connects to, and so on.  I will never shop without it again, and as for downloads?  Oh yeah, no software will pass these virtual lips until my poison tester checks it out for me.
