What is the fake "AdBlock — best ad blocker" browser extension?
While investigating untrustworthy websites, we found a page using an adult-oriented lure that promotes an installer containing "AdBlock — best ad blocker". There's a legitimate browser extension of the same name, which this piece of software imitates. This fake extension operates as adware; i.e., it displays ads. Additionally, this bogus browser extension collects sensitive user information.
"AdBlock — best ad blocker" adware overview
Adware stands for advertising-supported software. It is designed to generate revenue by feeding users with unwanted and deceptive adverts. This third-party graphical content (e.g., pop-ups, banners, coupons, overlays, etc.) can be displayed on visited websites and/or other interfaces.
It must be mentioned that adware might need certain conditions to run intrusive ad campaigns, such as compatible browser/system specs or user geolocation, visits to particular sites, etc. However, regardless of whether "AdBlock — best ad blocker" enables the placement of advertisements – its presence on a system remains a threat.
Adware-delivered adverts primarily endorse scams, unreliable/dangerous software, and potential malware. Some intrusive ads can even execute scripts to perform stealthy downloads/installations upon being clicked.
Keep in mind that while legitimate products or services might be encountered through these advertisements – they are highly unlikely to be promoted by their actual developers or other official parties. It is most probable that this promotion is undertaken by scammers who abuse the content's affiliate programs to obtain illegitimate commissions.
It is pertinent to mention that this "AdBlock — best ad blocker" uses the "Managed by your organization" Google Chrome feature to ensure persistence and complicate its removal.
Furthermore, this fake browser extension spies on users' browsing activity. Adware usually targets browsing and search engine histories, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, and so forth. The collected information can then be sold to third-parties or otherwise abused for profit.
To summarize, the presence of advertising-supported software like this fake "AdBlock — best ad blocker" extension on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Advertising-supported software usually appears legitimate/harmless, and it may even be disguised as existing apps or extensions. Users are enticed into downloading/installing adware by promises of various functionalities. However, these features seldom work as promised, and in most cases – they do not work at all.
It must be stressed that even if a piece of software operates as indicated by its promotional material – that is not definitive proof of legitimacy or safety.
How did fake "AdBlock — best ad blocker" install on my computer?
We obtained "AdBlock — best ad blocker" from a scam webpage using an adult-themed lure. From this page we downloaded an installer containing this fake browser extension.
Adware is commonly endorsed on deceptive sites, and it may have "official" promotional webpages. Most visitors access these pages via redirects caused by websites that employ rogue advertising networks, mistyped URLs, spam browser notifications, intrusive ads, or installed adware (with browser force-opening abilities).
Advertising-supported software can also be bundled with ordinary programs. The risk of unintentionally allowing bundled content into the system is increased by downloading from dubious channels (e.g., freeware and third-party websites, Peer-to-Peer sharing networks, etc.) and by rushing through installation processes (e.g., skipping steps, using "Easy/Quick" settings, etc.).
Intrusive advertisements proliferate adware as well. When clicked on, some of these adverts can execute scripts to perform downloads/installations without user consent.
How to avoid installation of adware?
We strongly recommend researching software and downloading it only from official/verified sources. Installation processes must be treated with care, e.g., by reading terms, exploring possible options, using the "Custom" or "Advanced" settings, and opting out of all additional apps, extensions, tools, etc.
Another recommendation is to exercise caution while browsing since fake and harmful online content usually appears legitimate and innocuous. For example, intrusive ads may look harmless – yet they redirect to highly questionable sites (e.g., gambling, pornography, adult dating, etc.).
In case of continuous encounters with such adverts and/or redirects, check the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with "AdBlock — best ad blocker", we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
