I'm not sure which one to use... Windows One Care Live Beta (available at microsoft.com) or Norton Security 2005. Attempting to install the Beta requires uninstalling Norton. Which should I use?
honestly I wouldn't use those.
That windows one is beta, so it might have quite many bugs in it. And I just don't like norton because I have had some many problems with it.
U could try the windows one, then if u don't like it put norton back.
