On Friday, September 30, Microsoft Forefront and Security Essentials, the two recommended antivirus solutions for campus network users, started misidentifying Google Chrome as a virus and automatically removing it from computers on which both are installed. Microsoft has since resolved the conflict by releasing new virus definitions for Forefront and Security Essentials but you must update your virus definitions (see instructions below) before you will be able to reinstall Chrome on affected computers.
After updating your virus definitions using the directions referenced below, you should be able to download. Chrome and reinstall the browser. If you have questions about any part of this process, please contact the IT Service Center at firstname.lastname@example.org or call 303-735-4357 (5-HELP from a campus phone).
