You can safely uninstall the sponsor by following the next steps:
1. uninstall plus! with sponsor (make sure you exit your internetbrowser fully, from taskbar and systray also)
2. if you used ad/spyware programs in between reinstall plus! again with sponsor as this could have crippled the uninstaller (if not go to step 4)
3. uninstall plus! again right away as said in point 1
4. reboot
5. reinstall plus! and select NO on the sponsoragreement (if you like to continue using plus!, plus! will install without the sponsor aswell)
This should totally remove the sponsor (toolbar etc etc).
For more detailed info have a look at
uninstalling the Messenger Plus! Sponsor Program
Asfor knobcastrulecopy.exe: i don't know wether this is part of the sponsor. Only Patchou can answer this one.
