Microsoft is aware of limited, targeted attacks that attempt to exploit a vulnerability in Internet Explorer 6, 7, 8, 9, 10 and 11.
For now, Information Technology is suggesting you use Chrome or Firefox for your browsing choice. Both may be downloaded and installed for free at https://google.com/chrome and https://www.mozilla.org/en-US/firefox/new.
Windows XP users are encouraged to select Chrome or Firefox as their primary browser now, since Windows XP is no longer supported, nor being updated by Microsoft. Any questions should be directed to the Help Desk at (269) 387-4357, option 1.
