What kind of application is OneBlock?
While testing the OneBlock application, our team noticed that it displays annoying advertisements. Thus, we classified OneBlock as adware (advertising-supported software). It is common for adware to be promoted and distributed using deceptive methods. We discovered OneBlock while analyzing a page running the "Your System Is Seriously Damaged" scam.
More about OneBlock
OneBlock is promoted as an app offering a much higher level of privacy when browsing the web. It is supposed to block advertisements. However, we learned that it shows them. Ads displayed by advertising-supported applications can lead to untrustworthy web pages.
Clicking those ads can open technical support scam pages, phishing websites, deceptive pages urging to install "updates" or shady applications, etc. Sometimes, ads shown by the adware can be designed to run certain scripts to download or install unwanted software. Thus, it recommended not to trust adware and ads displayed by it.
In addition to bombarding users with unwanted ads, OneBlock can read and change data on all websites. It may be gathering browsing-related and other information that could be sold to third parties, used for marketing purposes, or monetized in other ways.

More about adware
There are advertising-supported apps that can hijack web browsers (change their settings). Most browser-hijacking apps promote questionable search engines. These search engines can show misleading results (promote untrustworthy pages) and redirect to other dubious search engines.
How did adware install on my computer?
We discovered OneBlock on a deceptive page claiming that the operating system is infected with viruses. We also found that OneBlock has its official page. This app gets added after following the instructions provided on those pages.
In other cases, users install adware via freeware installers, fake installers, or untrustworthy advertisements. Installers containing adware have "Advanced", "Custom", or other settings. Users install adware when they leave those settings unchanged when installing software.
How to avoid installation of unwanted applications?
Download applications and files from reliable sources such as official web pages and verified stores. Do not trust advertisements on dubious pages or allow websites of this kind to show notifications. Deselect unwanted apps included in downloaders and installers before finishing downloads and installations.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
