I had a Yoggie a few years ago and was very impressed by it. I recently ordered one as was fed up with the speeds at which software based PC protection systems operated and how much resources they consumed. However, in combination with the supplied Kaspersky Virus scanner, between them they slowed my computer down and ensured that everyday working was rendered more difficult. My local network setup is slightly more complicated than most, with a Belkin Network USB Hub serving my printer and external storage, and a WD My Book World edition attached to my router. Once Yoggie was attached and the yoggiegui.exe running, I was unable to access my network drives, or my printer. After scouring the internet for support and contacting the various suppliers, I'd got no further in resolving the issues. Yoggie is great, but only if you have a simple network setup.
