How to remove DeviceHelper adware from Mac?

What is DeviceHelper?

DeviceHelper is a rogue application, which is categorized as adware. Additionally, this app has browser hijacker traits. It is designed to run intrusive advert campaigns and make alterations to browser settings - in order to promote fake search engines. DeviceHelper promotes d2sri.com on Safari browsers and search.basicgeneration.com - on Google Chrome. Most adware-types and browser hijackers collect browsing-related information. Due to the dubious methods used to distribute DeviceHelper, it is considered to be a PUA (Potentially Unwanted Application). This piece of software has been observed being proliferated via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers are used to spread not only PUAs but also trojans, ransomware and other malware.

DeviceHelper adware

Adware delivers banners, coupons, pop-ups, full-page and other intrusive advertisements. They diminish the browsing experience, as they overlay webpage content and slow down the browsing activity. Upon being clicked, intrusive ads redirect to unreliable/malicious websites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers operate by reassigning browsers' homepage, default search engine and new tab/window URLs - to the addresses of fake web searchers. Hence, with such a piece of software installed: every single search query typed into the URL bar and new browser tab/window opened - redirect to the promoted address. DeviceHelper promotes d2sri.com (on Safari) and search.basicgeneration.com (on Google Chrome) in this manner. Illegitimate search engines are seldom able to generate search results, so they redirect to Google, Yahoo, Bing and other genuine ones. Browser hijackers can limit/deny access to the browsers' settings and/or undo any permitted changes made. As mentioned in the introduction, most PUAs (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 being shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of unwanted software on devices can lead to system infections, severe privacy issues, financial losses and even identity theft. Therefore, it is strongly recommended to eliminate all suspect applications and browser extensions/plug-ins immediately upon detection.

SectionBufferWebAdviseSearch and StandardMethod are a few examples of other adware-type apps. They appear ordinary and offer a wide variety of functionalities. However, despite how good the promised features may sound - they are usually nonoperational. This applies to nearly all PUAs. The sole purpose of unwanted applications is to generate revenue for the developers; to users they have no real value and can cause serious problems. PUAs are designed to deliver intrusive ad campaigns, modify browsers, cause redirects and collect private data.

How did DeviceHelper install on my computer?

PUAs are distributed through download/installation setups of other programs. This false marketing tactic of packing regular software with unwanted or malicious additions - is termed "bundling". By rushing through download/installation processes (e.g. by ignoring terms, using pre-set options, etc.) - users risk inadvertently allowing bundled content into their devices. Some PUAs have "official" promotional pages, from which they can be downloaded. Once clicked on, intrusive advertisements can execute scripts to download/install these applications without user permission.

How to avoid installation of potentially unwanted applications?

It is advised to always research software prior to download/installation and/or purchase. Only official and verified download channels must be used. Unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders - are deemed to be untrustworthy, due to often offering harmful and/or bundled content. When downloading/installing, it is important to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, features, etc. Intrusive adverts appear legitimate and innocuous, however they redirect to highly questionable websites (e.g. gambling, adult-dating, pornography, and so forth). Should users encounter such ads and/or redirects, the devices must be inspected and all suspicious applications and browser extensions/plug-ins detected - removed from them without delay. If your computer is already infected with DeviceHelper, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
