Removing the Ultimate Ad Eraser adware-type browser extension
Written by Tomas Meskauskas on (updated)
What is Ultimate Ad Eraser?
While inspecting dubious download websites, our researchers found the Ultimate Ad Eraser browser extension. This piece of software is promoted as an adblocker - a tool capable of removing and altering online ads. However, after analyzing Ultimate Ad Eraser, we learned that it operates as adware instead. In addition to running intrusive advertisement campaigns, this extension also spies on users' browsing activity.
Ultimate Ad Eraser adware overview
Advertising-supported software (adware) enables the placement of various advertisements on visited sites and/or other interfaces. These adverts promote online scams, unreliable/harmful software, and malware. Some intrusive ads are even capable of performing stealthy downloads/installations - once clicked on.
Note that any legitimate products encountered through adware-delivered advertisements are highly unlikely to be promoted by their developers. Instead, this endorsement is undertaken by scammers abusing the products' affiliate programs to obtain illegitimate commissions.
It is pertinent to mention that advertising-supported software may require certain conditions (e.g., compatible browser/system specs, visits to particular websites, etc.) to deliver intrusive advert campaigns. However, regardless of whether Ultimate Ad Eraser (or other adware) displays ads - its presence on a system endangers device/user safety.
Furthermore, Ultimate Ad Eraser has data tracking abilities. Advertising-supported software typically collects the following information: browsing activity (e.g., visited URLs, searched queries, etc.), personally identifiable details, usernames/passwords, credit card numbers, and so forth. The collected data is usually monetized through sale to third-parties.
In summary, the presence of software like Ultimate Ad Eraser on devices can lead to system infections, serious privacy issues, financial losses, and identity theft.

Adware examples
We have analyzed thousands of adware samples; shade area, Weather, and Video Ad Remover are just a couple of our latest finds. This software appears legitimate and offers "handy" functionalities. However, these functions rarely work as promised, and in most cases - they are utterly nonoperational.
How did Ultimate Ad Eraser install on my computer?
We acquired Ultimate Ad Eraser from its "official" promotional webpage. Adware commonly has such pages, and it is endorsed through scam websites. Most users enter these webpages via redirects caused by sites using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive adverts, or adware (with browser force-opening capabilities).
Advertising-supported software can also be bundled (packed together) with ordinary programs. Download from untrustworthy sources (e.g., freeware and third-party websites, P2P sharing networks, etc.) and rushed installations - increase the risk of inadvertently permitting bundled content into the system.
Intrusive advertisements proliferate adware as well. Upon being clicked, some of these ads can execute scripts to make downloads/installations without user consent.
How to avoid installation of adware?
We strongly advise researching software and downloading it from official and verified channels. When installing, it is crucial to read teams, inspect possible options, use the "Custom/Advanced" settings, and opt-out of all additions.
We also recommend exercising caution when browsing - as fraudulent and malicious content tends to look harmless. For example, intrusive adverts appear genuine and innocuous, yet they redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, etc.).
If you experience ads/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 Ultimate Ad Eraser, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
