Uninstall OneCare
http://social.microsoft.com/Forums/en-US/onecaregeneral/thread/732e6371-2e71-479a-8cd6-b189941ed4fb, use the cleanup
tool: http://social.microsoft.com/forums/en-US/onecareinstallandactivate/thread/399071e2-49dc-4767-932d-d261e3965943/,
and then download and install the free Microsoft Security essentials for malware protection -

If you used OneCare for backups, you'll still be able to restore from old backups if you use the OneCare Restore tool -

but you'll need to seek an alternative backup solution.
