How to remove DeviceHelper adware from operating systems

What is DeviceHelper?

DeviceHelper is a rogue application categorized as adware. Additionally, this app has browser hijacker traits. It runs intrusive ad campaigns and makes alterations to browser settings to promote fake search engines. DeviceHelper promotes d2sri.com on Safari browsers and search.basicgeneration.com on Google Chrome.

Most adware-type apps and browser hijackers collect browsing-related information. Due to the dubious methods used to proliferate DeviceHelper, it is classified as a Potentially Unwanted Application (PUA). This software has been observed being proliferated via fake Adobe Flash Player updates.

Bogus software updaters/installers are used to spread PUAs and also Trojans, ransomware and other malware.

Adware delivers banners, coupons, pop-ups, full-page and other intrusive advertisements. These diminish the browsing experience, as they overlay web page content and reduce browsing speed. When clicked, intrusive ads redirect to dubious/malicious websites and some can even stealthily download/install software (e.g. PUAs).

Browser hijackers operate by reassigning the homepage, default search engine and new tab/window URLs to the addresses of fake search engines. Therefore, with this software installed, each search query typed into the URL bar and new browser tab/window opened redirects to the promoted address.

DeviceHelper promotes d2sri.com (on Safari) and search.basicgeneration.com (on Google Chrome) in this manner. Rogue search engines are seldom able to generate unique results, and so they redirect to Google, Yahoo, Bing and other genuine sites. Browser hijackers can limit/deny access to the browser settings and undo any permitted changes made.

As mentioned, most PUAs (including adware and browser hijackers) can track data. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details).

The collected data is then monetized by sharing with and selling to third parties (potentially, cyber criminals). In summary, the presence of unwanted software on devices can lead to system infections, serious privacy issues, financial loss and even identity theft.

Therefore, you are strongly advised to eliminate all suspect applications and browser extensions/plug-ins immediately upon detection.

SectionBuffer, WebAdviseSearch and StandardMethod are some examples of other adware-type apps. They may seem normal and offer a wide variety of functionality, however, despite how good the features promised may sound, they are usually nonoperational. This applies to most PUAs.

The sole purpose of these unwanted applications is to generate revenue for the developers. Regular users receive no value and can experience serious problems. PUAs deliver intrusive ad campaigns, modify browsers, cause redirects and collect private data.

How did DeviceHelper install on my computer?

PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".

By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well.

When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages from which they can be downloaded.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others).

If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately. If your computer is already infected with DeviceHelper, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
