I think so. I scrubbed it with your uninstaller, as well as RevoUninstaller, and also looked for remnants manually.

A further note…

Updates are now speedy with my custom install of v6, only a few seconds. Previously with the typical install it took at least 3-11 minutes for them to process and recognize the simple fact that the program/engine/virus definitions were already up to date. So I suspect that your new Script Shield was interfering here too!?
