SpeeditUp is a program that claims it checks your Internet connection for speed and performance issues. This in itself is not a bad thing, but SpeeditUp also displays intrusive advertisements on your desktop and on web sites that you visit. When visiting web sites, SpeeditUp will display ads in a way that makes it difficult to navigate or read the site. These ads will be labeled Ads by SpeeditUp and take up a large amount of a site’s visibility and are typically displayed over the the site’s content. Even more concerning, many of the ads that are displayed by SpeeditUp are for further adware installers that would cause even more damage to your computer.
