OIS Security Byte: Clearing the Cobwebs from your internet history

UNC’s Office of Information Systems will be posting bite-size IT Security tips for our users. As IT security concerns become more a part of our everyday life, awareness is one of our best allies. This edition focuses on Temporary Internet Files. For more information, contact your local IT Support or chat with us at help.med.unc.edu.

Your Internet History – Clearing out the Cobwebs

Temporary Internet Files cache web page content related to your browsing. Due to Outlook Web Access, they are also a source of unintended download of University-owned Sensitive Information.

As Project SIR (Sensitive Information Remediation) gets underway, you will save a lot of time if you empty these files before attempting to scan your drive with Identity Finder.

To that end, here are instructions for clearing Temporary Internet Files in the three major browsers on your PCs. (Due to different versions of the following browsers, your directions may be slightly different.)

Internet Explorer

  1. Open Internet Explorer.
  2. Click Tools button located in the upper right corner.
  3. Click the General tab, and then, under Browsing History, click Delete.
  4. Check the appropriate boxes (see below), click Delete, and then click OK.


Mozilla Firefox

  1. Open Mozilla Firefox.
  2. Click the Menu button in the upper right corner.
  3. Choose History and then Clear Recent History.
  4. Click the drop-down menu next to Time range to clear:
  5. Choose Everything.
  6. Click Clear Now.


Google Chrome

  1. Open Google Chrome.
  2. Click the Menu button in the top right corner.
  3. Select More Tools then Clear browsing data.
  4. Select the checkboxes for the desired data to be cleared (see below)
  5. Select beginning of time.
  6. Click Clear browsing data.
