Removal instructions for the Page Summarizer AI browser extension
Written by Tomas Meskauskas on (updated)
What kind of software is Page Summarizer AI?
While inspecting a Torrenting website that uses rogue advertising networks, our researchers discovered a deceptive page endorsing the Page Summarizer AI browser extension. Our research team also found its promotional webpage, wherein the extension is promoted as an AI-powered tool for summarizing the text content on any given site.
After our analysis, we determined that Page Summarizer AI is a browser hijacker. However, unlike the standard hijacker software, this extension does not alter browser settings nor generate redirects. Instead, it injects ads into search results.
Page Summarizer AI browser hijacker overview
Browser hijackers typically change browser settings (e.g., default search engines, homepages, new tabs/windows, etc.) – however, Page Summarizer AI makes no such modifications. While the purpose of said alterations is to cause redirects to fake search engines (that ultimately land on Google, Bing, Yahoo, or other legitimate Internet search sites), this does not apply to Page Summarizer AI.
The impact of having this rogue extension installed on a browser is that it alters search results. On our testing machine, the results produced by Google were injected with ads. This sponsored content may be irrelevant, untrustworthy, deceptive, and even malicious.
Furthermore, Page Summarizer AI utilizes the "Managed by your organization" feature to ensure persistence and prevent browser recovery.
What is more, browser hijackers usually have data-tracking abilities, and this might be true of Page Summarizer AI. Information of interest can include: URLs visited, webpages viewed, searched queries, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, and so on. This sensitive information can be shared with or sold to third-parties.
To summarize, the presence of browser-hijacking software like Page Summarizer AI on devices may lead to system infections, serious privacy issues, financial losses, and even identity theft.

Browser hijacker examples
As previously mentioned, browser hijackers typically modify browsers to generate redirects; Qtr Search, The Yellow Tab, and Customize Your New Tab are just a few examples of software matching this description.
Users may be enticed into downloading/installing browser hijackers by various "useful" functionalities. However, these functions seldom work as advertised, and in most cases – they do not work at all.
It must be stressed that regardless of whether a piece of software changes browser settings or operates as indicated by its promotional material – that does not prove its legitimacy or safety.
How did Page Summarizer AI install on my computer?
Page Summarizer AI has an "official" promotional webpage, and we discovered a fake movie download page endorsing an installer containing this rogue browser extension. It is noteworthy that such installation setups may include multiple pieces of unwanted/malicious software.
Sites that promote browser hijackers are primarily accessed via redirects generated by misspelled URLs, intrusive ads, websites using rogue advertising networks, spam browser notifications, and installed adware.
Browser-hijacking software is also proliferated using the bundling marketing technique, which entails packing regular program installers with undesirable/dangerous additions.
The risk of inadvertently allowing bundled content into the system is increased by downloading from dubious channels (e.g., freeware and third-party sites, P2P sharing networks, etc.) and by treating installation processes with negligence (e.g., using "Easy/Express" settings, etc.).
Intrusive adverts spread browser hijackers as well. Once clicked on, some of these advertisements can execute scripts to perform downloads/installations without user consent.
How to avoid installation of unwanted software?
We recommend researching software and downloading it only from official/verified sources. Installation processes must be approached with caution by reading terms, exploring possible options, using the "Custom/Advanced" settings, and opting out of all additional apps, extensions, features, tools, and so forth.
Another recommendation is to be careful while browsing since fake and malicious online content usually appears legitimate and harmless. For example, while intrusive ads may look innocuous – they redirect users to unreliable and questionable sites (e.g., scam-promoting, gambling, adult dating, pornography, etc.).
In case of continuous encounters with advertisements and/or redirects of this kind, inspect the device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Page Summarizer AI, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this rogue software.
