How to remove "BlockAll - block ads" adware and the adverts it displays
Written by Tomas Meskauskas on (updated)
What is "BlockAll - block ads"?
While inspecting deceptive websites, our researchers discovered the "BlockAll - block ads" browser extension. Its promotional material endorses this extension as an ad-blocking tool (adblocker). After analyzing "BlockAll - block ads", we determined that it operates as advertising-supported software (adware) instead.
"BlockAll - block ads" adware overview
Adware is designed to display advertisements on visited websites and/or different interfaces. These adverts promote untrustworthy/harmful websites and software, online scams, and even malware. Additionally, some intrusive ads can perform downloads/installations without user permission - once clicked on.
Any legitimate products encountered through these advertisements are unlikely to be promoted by their actual developers. This endorsement is primarily undertaken by scammers abusing the products' affiliate programs to acquire illegitimate commissions.
It is noteworthy that advertising-supported software may require certain conditions (e.g., compatible browser/device or user geolocation, visits to specific sites, etc.) - to run intrusive advertisement campaigns. Whether "BlockAll - block ads" (or other adware) displays adverts or not is irrelevant - its presence on a system endangers device/user safety regardless.
Furthermore, "BlockAll - block ads" has data tracking functionalities. Advertising-supported software typically collects browsing-related information, personally identifiable details, usernames/passwords, credit card numbers, and so on. The collected data can then be shared with and/or sold to third-parties.
In summary, the presence of software like "BlockAll - block ads" on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples
We have analyzed countless adware samples; Movies Craver, reuse tab, and Ultimate Ad Eraser are just a couple of our latest finds. Advertising-supported software usually appears legitimate and offers "useful" features. However, these functions rarely work as promised, and in most cases - they do not work at all.
How did "BlockAll - block ads" install on my computer?
We obtained "BlockAll - block ads" from its official download webpage. Adware is also commonly promoted on scam websites. Most users enter these pages through redirects caused by sites using rogue advertising networks, mistyped URLs, intrusive advertisements, spam browser notifications, or installed adware (with browser force-opening capabilities).
Additionally, advertising-supported software can be bundled (packed together) with ordinary programs. Download from dubious channels (e.g., unofficial and free file-hosting websites, P2P sharing networks, etc.) and rushed installations - increase the risk of allowing bundled content into the device.
Intrusive ads are used to distribute adware as well. When clicked on, some of these adverts can execute scripts to make downloads/installations without user permission.
How to avoid installation of adware?
We strongly recommend researching software and downloading only from official/verified channels. Additionally, when installing, it is important to read terms, inspect available options, use the "Custom/Advanced" settings, and opt-out of all supplements.
Another recommendation is to exercise caution when browsing - since illegitimate and malicious content appears harmless. For example, intrusive advertisements look innocuous yet redirect to highly questionable sites (e.g., gambling, adult-dating, pornography, etc.).
In case of encounters with such adverts/redirects, check the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with "BlockAll - block ads", we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
