This is what you’re supposed to do: scan for viruses, optimize your hard drive, back-up your files, and make sure you have a firewall up at all times. OneCare makes it possible to do all that stuff without spending a bunch of time doing it.
Because you want your PC to be safe, but, on the other hand, you have a life.
