What is Speed Check adware?
Speed Check is supposed to check the speed of websites. Although, it is known that this program functions as adware (it displays advertisements) and can read, and change data on visited websites. Speed Check is promoted on a dubious website. Therefore, it is categorized as a potentially unwanted application (PUA).
Speed Check adware in detail
Speed Check displays advertisements (pop-ups, banners, surveys, coupons, or other ads) that could open potentially malicious pages, various scams, sites asking to provide personal information, or other dubious pages. Also, those ads might be designed to run certain scripts to download or even install unwanted software.
Another issue with Speed Check is that it can collect various information. It is possible that this app gathers IP addresses, visited pages, or other browsing-related details, and even sensitive information like credit card details, usernames, passwords. Thus, Speed Check is not a trustworthy application.

Adware in general
Adware is a type of software that generates revenue for its developer by displaying advertisements. Also, it can be designed to gather various data and (or) promote a fake search engine. A couple examples of applications designed to deliver ads are TabMemoryOptimizer, Infogram, and Quantum Ad Blocker.
How did adware install on my computer?
Adware is distributed through downloaders and installers for other programs, fake installers, and advertisements. Downloaders and installers containing adware have "Custom", "Advanced", or some other settings. Users agree to download or install included adware when they download or install programs without changing those settings.
Advertisements cause unwanted downloads or installations when they are designed to run certain scripts. Those ads cannot download or install unwanted software unless users click on them.
How to avoid installation of potentially unwanted applications?
Avoid downloading files or programs from unreliable sources. They should be downloaded from official websites and via direct links. Do not download or install the software until all optional (and unwanted) downloads or installations are deselected. Also, avoid clicking on ads that appear on shady pages.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
