SiteAdvisor blog: The Web’s Download Disasters
When we first started crawling the Web looking for bad downloads last year, we weren’t sure what we’d find.

I can say with equal confidence that there’s also plenty of train wrecks waiting to happen to your PC.
These are the website you need to stay clear of like the plague. This is just sad and frightening how terrible some of these products are.
