Do not use Internet Explorer for the time being!

Published: 21st January 2020 Last updated: 16th March 2020

Microsoft has identified a critical vulnerability in Internet Explorer. Microsoft is working hard to remedy the situation but, until a solution has been found, LIS advises everyone not to use Internet Explorer. It is OK to use other browsers, such as Microsoft Edge or Google Chrome.

Additional notice: Exceptions for vital applications for which it is necessary to use Internet Explorer

Remote attackers can exploit the vulnerability in Internet Explorer to take control of your computer. While you surf on the internet, they can mislead you with specially crafted websites or infected ads. Opening them can result in damage. No further interaction with you as a user is necessary to gain access to your computer. The risks are not extreme at present. Since Microsoft has largely replaced Internet Explorer in Windows 10 by Microsoft Edge, there is a good chance that you are already using Edge.

Updating Internet Explorer can remedy the problem. Tilburg University will closely monitor when a patch becomes available and will implement the update as soon as it is available. Until then, please use browsers like Microsoft Edge or Google Chrome. Please note that the icon of Microsoft Edge closely resembles that of Internet Explorer. A tip: hovering your cursor over the icon will show you the name of the browser.

What steps can you take to protect yourself?

  1. Install Microsoft Edge or Google Chrome, rather than Internet Explorer, as your default browser.

You can change your default browser as follows.

  • Open the Start menu on your computer.
  • Click ‘Settings’.
  • Click ‘Apps’.
  • Open your Default apps.
  • Below, under Web browser, click on your present browser.
  • Change it into Microsoft Edge or Google Chrome.
  1. Have you recently used Internet Explorer? Think back whether you have visited unknown sites or seen anything suspicious, such as websites that opened spontaneously or peculiar ads. If this is the case, please report this immediately to CERT (e-mail:, phone: 013 - 466 3095).
