InternetSpeedTester

InternetSpeedTester is a Potentially Unwanted Program (PUP), which claims to provide users with direct access to a neat speed testing tool, which allows them to quickly check the speed of their Internet connection. While this might be useful situationally, you should be aware that there are hundreds of free speed testing services that do not require the installation of 3rd-party add-ons to use them. Another reason why you might want to stay away from InternetSpeedTester is that its installation might introduce unwanted changes to your Web browser's settings. For example, PUPs are known to often replace the default search engine or new tab page with a sponsored Web page.

The InternetSpeedTester's services also are nothing special since everything that the application does is to add a new button, which redirects the users to Fast.com – a trustworthy website that is not affiliated with InternetSpeedTester in any way. If you have installed InternetSpeedTester, we advise you to remove it to prevent this add-on from causing any annoying issues. However, its removal is not mandatory since InternetSpeedTester is not unsafe, but it is certainly the recommended way to proceed if you want to ensure seamless Web browsing sessions.
