I too stumbled across the same link a few days ago. I tried the Revo uninstaller. On their site, it says their software uses the original programs uninstaller to remove the program. I tried it anyway, with no luck.
I just finished looking at the HiJackThis log, and it doesn't reveal any related Logitech drivers/fragments. Nothing out of the ordinary. I was finally able to disable the driver. For some reason the disable command finally processed. The disabled driver still shows up in the system health report, but the system is now more responsive during reboots, logoffs, and shut downs.
I have a spare Raptor and I think I'll give a fresh install a try. Just for fun. Thank you for all your help. Much appreciated
