How to eliminate the Omni Ad Stopper adware-type browser extension

Also Known As: Ads by Omni Ad Stopper
Type: Adware
Damage level: Medium

What kind of software is Omni Ad Stopper?

Our researchers discovered the Omni Ad Stopper rogue browser extension during a routine investigation of suspect sites. This piece of software is endorsed as an adblocker – a tool that blocks online advertisements. However, upon examination, we determined that Omni Ad Stopper is advertising-supported software (adware).

Omni Ad Stopper adware overview

Adware operates by running intrusive advert campaigns. It enables the placement of third-party graphical content (e.g., pop-ups, banners, surveys, overlays, etc.) on visited websites and/or other interfaces.

It is noteworthy that to work as designed, advertising-supported software may need certain conditions, such as compatible browser/system specs or user geolocation, visits to particular sites, and so on. However, even if Omni Ad Stopper does not display advertisements – its presence on a system endangers device and user safety.

Adware-delivered adverts endorse online scams, unreliable/hazardous software, and even malware. When clicked on, some intrusive ads can execute scripts to perform stealthy downloads/installations.

Keep in mind that while legitimate products or services may be encountered through these advertisements – they are unlikely to be promoted by their actual developers.

Furthermore, software within this classification usually has data-tracking functionalities, and Omni Ad Stopper is not an exception. Information of interest may include: browsing and search engine histories, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, etc. The collected information can then be shared with and/or sold to third-parties.

To summarize, the presence of software like Omni Ad Stopper on devices can lead to system infections, serious privacy issues, financial losses, and identity theft.

Adware examples

We have examined thousands of adware samples; Error DirectorSite Resolver, and Web Ads Filter are merely a few of our latest finds.

Advertising-supported software typically appears legitimate and harmless. Users are enticed into downloading/installing adware by promises of 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 even if a piece of software operates as indicated by its promotional material – that is not definitive proof of either legitimacy or safety.

How did Omni Ad Stopper install on my computer?

Omni Ad Stopper has an "official" promotional webpage. Aside from such legitimate-looking pages, adware is endorsed on deceptive/scam sites.

Most users enter these webpages via redirects caused by mistyped URLs, websites utilizing rogue advertising networks, intrusive ads, spam browser notifications, or installed adware (with browser force-opening abilities).

Advertising-supported software can also be bundled with ordinary programs. The risk of allowing bundled content into the system is increased by downloading from dubious channels (e.g., freeware and third-party sites, Peer-to-Peer sharing networks, etc.) and by treating installations with negligence (e.g., using "Easy/Quick" settings, etc.).

Some intrusive advertisements can be triggered (by being clicked) to execute scripts that perform downloads/installations without user consent. These adverts are used to proliferate adware as well.

How to avoid installation of adware?

We strongly advise researching software and downloading it only from official/verified sources. Installation processes must be treated with caution, e.g., by reading terms, exploring available options, using the "Custom" or "Advanced" settings, and opting out of all additional apps, extensions, etc.

Another recommendation is to be careful while browsing since fraudulent and malicious online content usually appears legitimate and innocuous. For example, intrusive ads may look harmless yet redirect to unreliable and questionable websites (e.g., gambling, pornography, scam-promoting, adult dating, etc.).

If you keep encountering advertisements and/or 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 Omni Ad Stopper, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
