More about the Ad Block Ultra application
Ad Block Ultra displays annoying pop-ups, banners, coupons, and other ads. It may show ads used to promote shady applications (download pages for those apps), various scams, and other shady websites. Moreover, clicking those ads may cause unexpected downloads or installations.
It is worth mentioning that apps of this kind can promote fake search engines (hijack web browsers) by changing the settings of the affected browsers. Fake search engines cannot be trusted because they can generate misleading results and display results generated by untrustworthy search engines.

Unwanted applications in general
Applications like Ad Block Ultra often are distributed and promoted using deceptive techniques. Thus, most users download and install them unknowingly. Also, they can be used to collect information about users. If Ad Block Ultra is already installed on a browser, then we strongly advise removing it as soon as possible.
More examples of adware-type apps are Dark It Online, Dark-View, Blocksly.
How did adware install on my computer?
The Ad Block Ultra application has its official website. However, it is worth knowing that adware is often bundled with other software. It is included in downloaders and installers as an additional offer. Adware gets installed after finishing software installation without changing "Advanced", "Custom", or other settings presented in its installer.
In some cases, adware gets downloaded/installed through deceptive ads or fake pop-ups displayed by dubious websites. Either way, most users download or install adware unintentionally.
How to avoid installation of unwanted applications?
Do not click advertisements and fake "Download" (or similar) buttons appearing on shady websites. Download applications and files from legitimate sources such as official pages. Always use direct download links. Do not use unofficial pages, third-party downloaders, P2P networks, etc., as sources for downloading software.
Deselect unwanted applications included in downloaders/installers before downloading/installing software. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
