Removing the Extreme Security Adblocker adware-type browser extension

Also Known As: Ads by Extreme Security Adblocker
Type: Adware
Damage level: Medium

What kind of software is Extreme Security Adblocker?

While investigating suspect websites, our researchers discovered Extreme Security Adblocker. This browser extension is promoted as a security-oriented ad-blocking tool.

However, after examining this piece of software, we determined that it is adware. Hence, instead of removing adverts – it displays them. Additionally, this extension spies on users' browsing activity.

Extreme Security Adblocker adware overview

Adware stands for advertising-supported software. It runs intrusive ad campaigns. This software enables the placement of third-party graphical content (e.g., pop-ups, overlays, banners, coupons, etc.) on visited websites and/or different interfaces.

Adware-delivered advertisements mainly endorse online scams, untrustworthy/harmful software, and even malware. Once clicked on, some of the ads can execute scripts to perform downloads/installations without user consent.

It is noteworthy that while legitimate products or services may be encountered via these adverts – they are 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 in order to obtain illegitimate commissions.

Advertising-supported software may need certain conditions to deliver intrusive advertisement campaigns, such as a compatible browser/system or user geolocation, visits to particular sites, etc. However, regardless of whether Extreme Security Adblocker displays advertisements – its presence endangers device and user safety.

What is more, this rogue browser extension has data-tracking functionalities. Information of interest may include: visited URLs, viewed pages, searched queries, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, and so forth. The collected information can then be shared with and/or sold to third-parties.

To summarize, the presence of software like Extreme Security Adblocker on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples

We have investigated thousands of adware samples; Daily GuardYTube AdSkipperBlockAll - block ads, and DarkiTon are merely some examples.

Software within this classification typically appears legitimate and innocuous. It can also offer a broad range of functionalities (e.g., ad-blocking, dark mode, easy access to online content, etc.) to lure users into downloading/installing the adware. The promised functions are usually nonoperational.

It must be mentioned that even if a piece of software works as indicated by its promotional material – that is not definitive proof of either legitimacy or safety.

How did Extreme Security Adblocker install on my computer?

We acquired Extreme Security Adblocker from its "official" promotional webpage. In addition to such pages, this software is commonly pushed through scam sites.

Users primarily access these webpages via redirects caused by websites utilizing rogue advertising networks, mistyped URLs, spam browser notifications, intrusive ads, or installed adware (with browser force-opening capabilities).

Advertising-supported software can also be bundled with regular programs. Downloading from untrustworthy sources (e.g., freeware and free file-hosting sites, P2P sharing networks, etc.) and rushing through installation processes (e.g., ignoring terms, skipping steps, using "Easy/Quick" settings, etc.) – increase the risk of inadvertently allowing bundled content into the system.

Additionally, intrusive adverts spread adware. Once clicked on, some of the advertisements can execute scripts to perform stealthy downloads/installations.

How to avoid installation of adware?

We strongly recommend researching software before downloading or purchasing it. Additionally, all downloads must be performed from official and verified channels. When installing, it is important to read terms, study possible options, use the "Custom/Advanced" settings, and opt out of all supplementary apps, extensions, tools, and so on.

Another recommendation is to be careful while browsing since fake and malicious online content. For example, intrusive adverts may look harmless – yet redirect to unreliable and hazardous websites (e.g., gambling, pornography, scam-promoting, adult dating, etc.).

In case of continuous encounters with such ads/redirects, check the system and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with Extreme Security Adblocker, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
