Removing the CleanBlocker adware and the adverts it displays

Also Known As: Ads by CleanBlocker
Type: Adware
Damage level: Medium

What is CleanBlocker?

CleanBlocker is a rogue browser extension that our researchers discovered while inspecting deceptive websites. This piece of software is presented as an adblocker that can stop website tracking and block various advertisements. However, our analysis revealed that CleanBlocker's operates oppositely - it runs intrusive advertisement campaigns. Due to this behavior, this extension is classified as adware.

CleanBlocker adware overview

Adware stands for advertising-supported software. It displays pop-ups, banners, coupons, and various other ads on visited websites and/or different interfaces. Furthermore, some intrusive advertisements can be triggered (by being clicked) to perform downloads/installations without user permission.

It is pertinent to mention that while legitimate content can be encountered through these adverts - it is unlikely to be promoted by the actual developers. Scammers often abuse the affiliate programs of genuine products in order to acquire illegitimate commissions for the promotion.

It is noteworthy that advertising-supported software may require certain conditions to run intrusive ad campaigns (e.g., compatible browser/system specs or user geolocation, visits to specific sites, etc.). However, even if CleanBlocker does not deliver ads - its presence endangers device and user safety.

What is more, this browser extension spies on users' browsing activity. Targeted data can include: visited URLs, viewed webpages, searched queries, personally identifiable details, account log-in credentials, credit card numbers, etc. The collected information can then be shared with and/or sold to third-parties.

To summarize, the presence of advertising-supported software like CleanBlocker on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples

Web Video PlayerMoviesMulticheck Checkbox Checker, and tabs info are merely some examples of adware that we have analyzed recently. This software rarely looks suspicious, it tends to appear legitimate and harmless. Adware also offers various "useful" features, which are usually nonoperational.

How did CleanBlocker install on my computer?

We acquired CleanBlocker from a scam page and found the extension's "official" promotional site. Most visits to such webpages are paid via redirects caused by misspelled URLs, websites using rogue advertising networks, intrusive ads, spam browser notifications, or installed adware (with browser force-opening abilities).

Furthermore, "bundling" - packing regular program installers with unwanted/malicious additions - is used to proliferate adware. Download from dubious sources (e.g., freeware and third-party websites, Peer-to-Peer sharing networks, etc.) and rushed installations (e.g., ignored terms, used "Easy/Quick" settings, etc.) increase the risk of allowing bundled content into the device.

Intrusive advertisements are also used to distribute advertising-supported software. Once clicked on, some of the adverts can execute scripts to make downloads/installations without user consent.

How to avoid installation of adware?

We strongly recommend researching software and downloading it from official/verified channels. Additionally, installation must be treated with caution, e.g., by reading terms, studying available options, using the "Custom/Advanced" settings, and opting-out of all supplements.

We also advise being careful when browsing since fraudulent and malicious content usually appears legitimate. For example, intrusive ads may look innocuous yet redirect to highly questionable websites (e.g., gambling, pornography, adult-dating, etc.).

In case of encounters with adverts/redirects of this type, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with CleanBlocker, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
