Open up Internet Explorer and click on Tools then select Internet Options…
Under Internet Properties click on the Advanced tab and under Settings scroll down and uncheck Enable third-party browser extensions and click Ok.
Now restart IE and the extensions will be disabled.
You can then re-enable them when you know a site can be trusted and you want to be able to use its services. This will help avoid malware when you visit a site that wants to install an extension and you’re not sure about it.
