What is BestADSBlock?
BestADSBlock is a rogue browser extension classified as a browser hijacker. It operates by modifying browser settings to promote bestadsblock.com fake search engine. BestADSBlock also spies on users' browsing activity. Due to questionable methods used to distribute browser hijackers, they are categorized as PUAs (Potentially Unwanted Applications).
BestADSBlock browser hijacker in detail
Browser hijackers reassign browsers' default search engine, homepage, and new tab/window URLs - to fake web searcher addresses. BestADSBlock modifies browsers in this manner as well. Hence, with it installed: every new browser tab/window opened and search query typed into the URL bar - redirect to bestadsblock.com.
Fraudulent search engines typically cannot provide search results, so they redirect to (or cause redirection chains ending with) Yahoo, Bing, Google, and other legitimate ones. This applies to bestadsblock.com as well; it redirects both to Yahoo (search.yahoo.com) and the nearbyme.io fake web searcher (possibly others). While nearbyme.io can generate search results, they are inaccurate and may endorse untrustworthy/malicious websites.
Browser hijackers can restrict or deny access to the browser settings. Alternatively, they can undo any changes users try to make to their browsers. Therefore, restoring a hijacked browser is impossible without removing the software affecting it.
What is more, BestADSBlock has data tracking abilities. Information of interest includes: URLs visited, pages viewed, search queries typed, IP addresses/ geolocations, personally identifiable details, and so on. Browser hijacker developers monetize the collected data by sharing it with and/or selling it to third-parties.
In summary, the presence of data-tracking software on devices can lead to serious privacy issues, financial losses, and even identity theft. To protect device integrity and user privacy, all suspicious applications and browser extensions/plug-ins must be removed immediately upon detection.

Browser hijackers in general
FreeSearchMusic, BestSearchPDF, CheckAMap, TopSearchStreams, and HDMusicStreamSearches are some examples of browser hijackers. They appear legitimate and offer various "handy" features. However, the promised functions are seldom operational.
In fact, nearly all PUAs entice users into download/installation with nonexistent functionalities. The sole purpose of unwanted apps is to generate revenue for the developers; they have no real value to users. PUAs are designed to hijack browsers, cause redirects, run intrusive advertisement campaigns (adware), and collect private information.
How did BestADSBlock install on my computer?
Select PUAs (e.g., BestADSBlock) have "official" promotional sites from which they can be downloaded and/or purchased. These applications are also proliferated via intrusive adverts. Once clicked on, the ads can execute scripts to make downloads/installations without user permission.
PUAs are most commonly spread through downloaders/installers of other programs. This false marketing tactic of packing regular software with unwanted/malicious additions - is called "bundling". Rushed download/installation processes (e.g., skipped steps and sections, etc.) increase the risk of allowing bundled content into the system.
How to avoid installation of potentially unwanted applications?
It is recommended to research software prior to download/installation and/or purchase. Additionally, all downloads must be done from official and trustworthy sources. Dubious download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled and harmful content.
When downloading/installing, it is important to read terms, study available options, use the "Custom/Advanced" settings to opt-out from additional apps, tools, features, etc. Intrusive advertisements appear legitimate; however, they redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, and so forth).
In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with BestADSBlock, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
