Written by Tomas Meskauskas on
What kind of software is Ad Blocker Pro Shield?
Our researchers discovered the Ad Blocker Pro Shield browser extension while investigating deceptive websites. This extension is promoted as a powerful advertisement-blocking tool that emphasizes privacy. Upon inspection, we determined that Ad Blocker Pro Shield operates as adware. Therefore, instead of eliminating ads – it displays them.
Ad Blocker Pro Shield adware overview
Adware stands for advertising-supported software. Its purpose is to generate revenue for its developers/publishers through advertising. Typically, adware functions by displaying ads on various interfaces (e.g., visited sites, desktops, etc.).
Certain conditions may be necessary for the software to work as intended (e.g., compatible browser/system or user geolocation, visitors to specific websites, etc.). However, even if Ad Blocker Pro Shield does not deliver adverts – its presence endangers device integrity and user privacy.
Adware-displayed advertisements can promote online scams (phishing, tech support, etc.), untrustworthy/hazardous software (adware, browser hijackers, PUAs, etc.), and malware (trojans, ransomware, etc.). Some of the ads can execute scripts to perform downloads/installations without user consent.
Keep in mind that while legitimate products or services may be encountered via these adverts – they are unlikely to be endorsed in this manner by any official parties. It is most probable that this endorsement is undertaken by scammers who abuse the promoted content's affiliate programs to obtain illegitimate commissions.
Additionally, Ad Blocker Pro Shield has data-tracking functionalities. Information of interest may include: URLs visited, webpages viewed, search queries typed, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, and so forth. The gathered information can be shared with or sold to third-parties.
In summary, the presence of software like Ad Blocker Pro Shield on devices can lead to system infections, severe privacy issues, financial losses, and identity theft.

Adware examples
We have investigated countless adware samples; PDF Converter Online, Adblock Bear - stop invasive ads, Online Manuals Discovery, and Neptune | Ad Blocker are merely some of our newest articles.
Advertising-supported software typically appears genuine and harmless. Users can be enticed into downloading/installing adware by promises of useful functionalities. However, these functions seldom work as advertised, and in most cases – they do not work at all.
It must be mentioned that even if a piece of software works exactly as described by its promotional material – that is not definitive proof of either legitimacy or safety.
How did Ad Blocker Pro Shield install on my computer?
Ad Blocker Pro Shield has an "official" promotional page. Software of this kind is also endorsed on scam websites that use various lures like updates, system infections, etc.
Most visitors access these webpages through redirects caused by intrusive ads, sites utilizing rogue advertising networks, misspelled URLs, spam browser notifications, and installed adware (with browser force-opening abilities).
"Bundling" – packing regular program installation setups with unwanted/malicious additions – is also used to proliferate adware. Downloading from untrustworthy sources (e.g., freeware and free file-hosting websites, P2P sharing networks, etc.) and rushing through installations (e.g., ignoring terms, using "Easy/Quick" settings, etc.) – increase the risk of inadvertently permitting bundled content into the device.
Intrusive advertisements spread advertising-supported software directly as well. Upon being clicked, some of these adverts can execute scripts to carry out stealthy downloads/installations.
How to avoid installation of adware?
We strongly advise researching software and downloading it only from official/verified channels. When installing, it is crucial to read terms, study possible options, use the "Custom/Advanced" settings, and opt out of all supplements (e.g., apps, extensions, features, tools, etc.).
Another recommendation is to be vigilant when browsing since the Internet is rife with well-disguised fake and malicious online content. For example, despite their ordinary/innocuous appearance – intrusive ads redirect to highly questionable sites (e.g., gambling, scam-promoting, adult dating, etc.).
Should you keep encountering adverts/redirects of this kind, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Ad Blocker Pro Shield, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
