I wasn't sure where to post this, so I hope it's OK here.
I removed my NIS 2010 yesterday from my XP system because I was going to install Comcst Norton Security Suite to use for troubleshooting purposes. I went thru the uninstall from Add/Remove Programs, ran the NRT and installed the CNSS. No problems at all other than the download from Comcast was not the curent version - had to run manual LiveUpdate three times to get up to the current version.
I left the Quick Scan run and looked around inside it checking out different settings and shut it down for the day.
Today I went back to the XP system since moggy had some questions about Norton PC Checkup, thinking since I ran the NRT I would have to reinstall Norton PC Checkup again!
WRONG - the NRT did not remove Norton PC Checkup - I felt sure the NRT would remove it. I ran the Norton PC Checkup and it ran fine.
So FWIW, NRT does not remove everything Norton as I was under the assumption it did.
