Add-ons, also known as ActiveX controls, browser extensions, browser helper objects, or toolbars, can improve your experience on a website by providing multimedia or interactive content, such as animations. However, some add-ons can cause your computer to stop responding or display content that you don't want, such as pop-up ads.
If you suspect that browser add-ons are affecting your computer, you might want to disable all add-ons to see if that solves the problem.
If disabling all add-ons solves the problem, you might want to use Add-on Manager to disable all add-ons permanently and then turn on add-ons only as you need them. To disable an add-on, follow the steps below.
Open Internet Explorer by clicking the Start button . In the search box, type Internet Explorer, and then, in the list of results, click Internet Explorer.
Click the Tools button, and then click Manage Add-ons.
Under Show, click All Add-ons.
Click the add-on you want to disable, and then click Disable.
Repeat step 4 for every add-on you want to disable. When you are finished, click Close.
