Forget when you last tuned up your PC? Sometimes we do, too, even here at the Windows Live OneCare safety scanner ranch. But now it doesn’t matter, because the latest version of the Windows Live Toolbar will tell you. You can look to the PC health icon to let you know whether it’s time to run a full-service scan on your computer and to warn you when you’ve surfed to a suspicious Web site that might be phishing for your personal information.

Windows Live OneCare Advisor reminds you, by way of a little yellow shield icon, to run a full-service scan every 30 days to check for viruses, spyware, and other potentially unwanted software and to improve your computer’s performance by getting rid of junk on your hard disk.

But you don’t have to wait 30 days—OneCare Advisor is poised on your Toolbar, ready to give you access to the safety scanner any time you’re worried about exposure to viruses or spyware or if you just feel like your computer is slower than it ought to be.

Alas, while the safety scanner can evaluate the current health status of your computer and fix immediate issues, it can’t protect your computer from threats or problems between scans. For always-on security and regular, automatic PC maintenance, check out Windows Live OneCare, the new PC health service from Microsoft. They’re running a 90-day free trial right now!
