I use to LOVE Norton, til this past year when it started clogging up my computer and couldn't use the Live Update (2004). Tried to uninstall and go back to 2003 and couldn't. Then I tried to reinstall and couldn't. Had to reformat...when I did that, I put 2003 on and then Live Update stopped working on it, cause of a mix up between it and the 2004 Live Update. So I uninstalled it, thankfully got it all off, but had to do a regedit to do it.
Then I tried some of the others before I found out about AVG Free, unfortunately. Liz
