What if new viruses or other Internet threats come out?
Windows Live OneCare regularly updates itself based on emerging Internet threats so you can have better peace of mind.
What is a PC tune-up, and how is it done?
A PC tune-up is pretty much like a tune-up for your car: a series of maintenance tasks to keep it running at optimum speed and efficiency. After installation, Windows Live OneCare will automatically run your first tune-up at 1:00 a.m., then once every four weeks after that. Tune-ups can take a while, and that’s why they’re scheduled for a time when you most likely won’t be using your computer. But that’s your choice. Tune-ups can be done whenever you want.
