How to remove OneUpdater adware from operating systems
Written by Tomas Meskauskas on (updated)
What kind of software is OneUpdater?
OneUpdater is rogue software classified as adware. Following successful infiltration, it runs intrusive advertisement campaigns. Therefore, this app delivers various unwanted and even dangerous ads. Additionally, most adware-type software monitors users' browsing activity, and it is highly likely that OneUpdater does so as well.
OneUpdater adware in detail
Adware delivers pop-ups, banners, coupons, surveys, full-page and other intrusive advertisements. These significantly diminish the browsing experience, since they limit browsing speed and overlay web page content, however, these ads are more than just a nuisance.
When clicked they can redirect to various sale-based/promotional, rogue, compromised, deceptive/scam and malicious websites. Visiting these sites poses a significant threat to device/user safety. Additionally, when clicked, some intrusive ads can execute scripts designed to download/install rogue software.
In summary, the presence of these unwanted apps on devices can result in system infections, financial loss, serious privacy issues and even identity theft. To protect device integrity and user safety, remove all suspect applications and browser extensions/plug-ins immediately upon detection.

Adware in general
Media Converter Pro Promos, Easy Weather Today Promos, Free Package Tracker Plus, and Free File Converter Pro are some examples of other adware-type apps. They may seem legitimate and innocuous, and users are often enticed into download/installation with offers of various "useful" features.
Despite how good the functions promised may sound, they rarely work. In fact, this information is true of most adware-type apps. The only purpose of this unwanted software is to generate revenue for criminals. Adware can delivers intrusive ad campaigns, cause redirects to untrusted and malicious websites, hijack browsers and gather sensitive data.
How did OneUpdater install on my computer?
OneUpdater has an "official" promotional web page from which it can be downloaded, however, it has also been observed being promoted by scam sites. Promotional and deceptive web pages is not the only way that adware spreads. Software of this type is distributed via the download/installation set-ups of other products.
This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling". Rushing download/installation processes (e.g. ignoring terms, skipping steps and sections, etc.) increases the risk of unintentionally allowing bundled content into the device.
Intrusive ads can infiltrate these applications into systems as well. Once clicked, they can execute scripts to download/install adware and other unwanted apps without users' permission.
How to avoid installation of unwanted applications
You are advised to research all software before download/installation and/or purchase. Use only official and verified download channels. Untrusted sources such as 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 the terms, study all possible options, use the "Custom" or "Advanced" settings and opt-out of supplementary apps, tools, functions, etc. Intrusive advertisements may seem normal, however, they can redirect to various dubious pages (e.g. gambling, pornography, adult-dating, and so on).
If you encounter ads/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 OneUpdater, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
