That's right, those files you quoted are viruses. You can only downld what other people decide to share. And although there might be others, they might not be online at that time. Since people from all time zones all over the world use gnutella.

But if you'd prefer DC then go for it. Your choice. I was going to suggest, vary your search, ... you searched registry ... what about cleaner or registry cleaner - .zip or .. .rar .... see there's many ways to search a file.

Yes DC is reasonably good. But ... it has its downsides too. If you're going to use both then why not... get the best of both worlds!
