1. Disable Internet Explorer add-ons. Open Internet Explorer and click 'Tools.' Select 'Manage Add-ons.' A box will appear on the page with a list of different toolbars and extensions. Scroll through the different add-ons and highlight any add-on that is listed as 'Enabled.' Then, click the 'Disable' tab at the bottom of the box to disable that add-on. Do this for every add-on and then close the box. Close Internet Explorer and open the browser again.
2. Reset your version of Internet Explorer. Open Internet Explorer and once again click 'Tools.' This time, you will need to choose 'Internet Options.' A small box will pop up. Click the 'Advanced' tab at the top of the box. Then, click the 'Reset' button. Doing so will reset Internet Explorer back to the default settings.

3. Search for updates for your version of Internet Explorer. Open Internet Explorer and this time click the 'Safety' option at the top of the browser. Then, select 'Windows Update.' Your browser will then open the Windows Update Web page. Click the 'Express' tab on that Web page. If there are any updates available, they will appear on the Web page. You will then be able to download updates by clicking the 'Install Updates' tab.
4. Scan your computer for any malware. Infections such as viruses, spyware and adware can cause Internet Explorer to close down. To be safe, it's wise to use both an anti-spyware program and an anti-virus program. You can download both of these programs (see Resources below).
5. Download and reinstall Internet Explorer. If performing the above steps did not solve your problem, your best bet is to just reinstall the program. Download the newest version of Internet Explorer (see Resources below).
