An important notice for users of Internet Explorer

May 1: Microsoft has released a patch for the Internet Explorer security flaw that was announced earlier this week.

Customers who have configured their operating systems to automatically apply security updates will not have to take any action.  Customers who manually apply security updates are encouraged to install the patch as soon as possible.

McMaster’s IT security team recommends that all those who use the Microsoft operating system apply this patch as soon as possible, whether they use Internet Explorer or not. IT security also recommends that everyone who uses the Windows XP operating system consider upgrading to a modern and supported system, such as Windows 7 or Windows 8.1 as soon as possible.

April 30: A security issue affecting Microsoft’s Internet Explorer web browser could let hackers take over your computer.

The bug affects all versions of Internet Explorer, but recent cyberattacks have targeted versions 9 and higher.

University Technology Services recommends using an alternate browser, such as Firefox or Chrome, until a patch is available.

If you must continue using Internet Explorer, UTS’ IT security team recommends following these instructions.
