For all you Google Chrome browser users, it seem that the anti-virus applications Microsoft Security Essentials and Forefront (which is what we use on campus) have classified Chrome as malware and is removing it. Jason had this happen. There’s some good news: if you use the sync functionality, your settings, plu-ins, etc. should not be touched upon reinstall. We don’t have Chrome on the public computers.
