How to remove the Tab Session adware-type browser extension
Written by Tomas Meskauskas on (updated)
What is Tab Session?
While checking out deceptive websites, our researchers discovered the Tab Session browser extension. It is presented as a productivity improvement tool that promises easy access and navigation on browsers. However, Tab Session operates as adware. This browser extension runs intrusive ad campaigns and spies on users' browsing activity.
Tab Session adware overview
Adware stands for advertising-supported software. It delivers intrusive advertisement campaigns, i.e., displays ads on visited websites and/or other interfaces. These adverts promote online scams, untrustworthy/harmful software, and even malware. Some intrusive advertisements can perform stealthy downloads/installations once clicked on.
It is pertinent to mention that any legitimate products/services encountered through these ads are unlikely to be promoted by their actual developers. Instead, scammers often abuse affiliate programs of genuine content in order to obtain illegitimate commissions for its promotion.
Additionally, it is noteworthy that adware may require specific conditions to run intrusive advert campaigns (e.g., compatible browser/system or user geolocation, visits to particular sites, etc.). However, even if Tab Session does not display advertisements - its presence on a system endangers device/user safety.
Tab Session has data-tracking abilities, and that includes access to the browsing history and bookmarks. However, this extension might also target other information. Adware typically gathers personally identifiable details, usernames/passwords, finance-related information, and other vulnerable data. The collected information can be monetized via sale to third-parties or otherwise abused for profit.
To summarize, the presence of advertising-supported software like Tab Session on devices can result in system infections, severe privacy issues, financial losses, and identity theft.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner.
We have inspected thousands of adware samples; Videos, Storage Controller, Cyber Shield, Ads Blocker Pro, and Websites Drawer are merely some of our newest finds.
This software usually appears legitimate and offers various functionalities. However, these features seldom work as promised, and in most cases - they are utterly nonoperational. Even if the software is functional - that is not proof of its legitimacy or safety.
How did Tab Session install on my computer?
We acquired Tab Session from a fake Chrome update website, and we found the extension's "official" promotional page. Users typically enter sites of this type via redirects caused by webpages using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive ads, or installed adware (with browser force-opening capabilities).
Intrusive advertisements proliferate advertising-supported software as well. Once clicked on, some of the adverts can execute scripts to perform downloads/installations without user consent.
"Bundling" - packing regular program installation setups with unwanted/malicious additions - is also used to distribute adware. Downloading from dubious channels (e.g., unofficial and freeware websites, P2P sharing networks, etc.) and rushing through installation processes (e.g., using "Easy/Quick" settings, etc.) - increase the risk of allowing bundled content into the device.
How to avoid installation of adware?
We strongly recommend researching software and downloading only from official and verified sources. Installation processes must be treated with caution, e.g., by reading terms, studying possible options, using the "Custom/Advanced" settings, and opting-out of all additional apps, extensions, tools, etc.
We advise being careful while browsing since fake and malicious online content usually appears legitimate and innocuous. For example, intrusive ads look harmless yet redirect to highly questionable websites (e.g., gambling, pornography, adult-dating, etc.).
In case of encounters with such advertisements/redirects, check the device and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with Tab Session, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
