OneUpdater adware removal instructions

What is OneUpdater?

OneUpdater is a piece of rogue software, classified as adware. Following successful infiltration, it runs intrusive advertisement campaigns. In other words, this app delivers various undesirable and even dangerous ads. Additionally, most adware-types spy on users' browsing activity and it is highly likely that OneUpdater does so as well. Due to the dubious techniques used to distribute it, OneUpdater is considered to be a PUA (Potentially Unwanted Application).

Website used to promote OneUpdater adware

Adware delivers pop-ups, banners, coupons, surveys, full-page and other intrusive advertisements. They seriously diminish the browsing experience, since they limit the browsing speed and overlay page content. However, these ads are more than just a nuisance. Upon being clicked they redirect to a variety of sale-based/promotional, rogue, compromised, deceptive/scam and malicious websites. Visiting such sites poses a significant threat to device/user safety. Additionally, when clicked on, some intrusive adverts can execute scripts, designed to download/install software. One prime example of content infiltrated into systems in this manner are PUAs. Unwanted applications can have varied abilities/features, aside from delivery of intrusive ad campaigns. Some types can force-open unreliable and malicious webpages. Browser hijacker type PUAs reassign browsers' homepage, default search engine and new tab/window URLs - to the addresses of fake search engines. Hence, with such a piece of software installed: new browser tabs/window opened and search queries typed into the URL bar - redirect to the promoted address. Illegitimate search engines are seldom capable of providing search results, so they redirect to Google, Yahoo, Bing and other legitimate ones. Furthermore, recovering a hijacked browser is impossible without removing the software affecting it. What is more, most PUAs (regardless of type / other functionalities) can track data. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The gathered information is typically shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of unwanted apps on devices can result in system infections, financial losses, serious privacy issues and even identity theft. To protect device integrity and user safety, all suspect applications and browser extensions/plug-ins must be eliminated immediately upon detection.

Media Converter Pro PromosEasy Weather Today PromosFree Package Tracker PlusFree File Converter Pro are some examples of other adware-type apps. They usually appear legitimate and innocuous. Users are enticed into download/installation with offers of various "handy" features. However, despite how good the promised functions may sound - they rarely work. In fact, this is true of practically all PUAs. Functionality and user safety are irrelevant, since the only purpose of unwanted software is to generate revenue. PUAs are designed to deliver intrusive advert campaigns, cause redirects to untrustworthy and malicious websites, hijack browsers and gather sensitive data.

How did OneUpdater install on my computer?

OneUpdater has an "official" promotional page, from which it can be downloaded. However, it has also been observed being promoted by scam sites. Promotional and deceptive webpages are not the only way that PUAs are spread. These app are distributed via download/installation setups of other products. This false marketing tactic of packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g. ignored terms, skipped steps and sections, etc.) - increase the risk of unintentionally allowing bundled content into the device. Intrusive ads can infiltrate such applications into systems as well. Once clicked on, they can execute scripts to download/install PUAs without user permission.

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation and/or purchase. Only official and verified download channels must be used. Untrustworthy sources, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content. When downloading/installing, it is important to read terms, study all possible options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, functions, etc. Intrusive advertisements appear ordinary, however they redirect to various questionable pages (e.g. gambling, pornography, adult-dating, and so on). Should users encounter adverts/redirects of this kind, they must inspect the system and immediately remove all suspicious applications and/or browser extensions/plug-ins from it. If your computer is already infected with OneUpdater, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this adware.
