How to eliminate OffersPrimary adware and the adverts it delivers

Also Known As: Ads by OffersPrimary
Type: Mac Virus
Damage level: Medium

What is OffersPrimary?

OffersPrimary is a piece of rogue software classified as adware. It also has browser hijacker traits. Since such dubious apps are usually downloaded/installed unintentionally, they are also deemed to be PUAs (Potentially Unwanted Applications).

OffersPrimary adware

OffersPrimary adware overview

Adware can display pop-ups, surveys, banners, coupons, and other intrusive adverts on visited websites and/or different interfaces. The delivered ads endorse a wide variety of online scams, untrustworthy and dangerous sites, as well as unwanted and malicious apps. What is more, some intrusive adverts can stealthily download/install software (e.g., PUAs) - when clicked on.

Browser hijackers cause redirects to fake search engines once a new browser tab/window is opened, or a search query is typed into the URL bar. This software does this by resetting the browsers' homepage, default search engine, and new tab/window URLs - to the promoted address.

Illegitimate search engines tend to redirect to genuine ones (e.g., Google, Yahoo, Bing, etc.) due to being incapable of generating search results. Browser hijackers also use persistence-ensuring methods to stop users from recovering their browsers.

Most PUAs collect sensitive information, e.g., visited URLs, viewed pages, searched queries, personally identifiable details, usernames/passwords, credit card details, and so forth. The gathered data is monetized through sale to third-parties.

In summary, the presence of unwanted software on devices can result in system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples

ActiveCoordinatorCheckFeatureConnectProcess - are a couple examples of adware. Software of this kind appears legitimate yet seldom works as promised. Fake features and disregard for user safety are typical of practically PUAs. The only goal of unwanted apps is to generate profit at user expense.

How did OffersPrimary install on my computer?

PUAs can have "official" promotional/download webpages. These applications can be downloaded/installed together with other software as well. This marketing technique of packing regular programs with unwanted/malicious supplements - is named "bundling". Additionally, intrusive advertisements can download/install PUAs without user consent - upon being clicked.

How to avoid installation of potentially unwanted applications?

It is important to always research software and only download it from official/verified sources. Dubious download channels, e.g., unofficial and freeware websites, Peer-to-Peer (P2P) sharing networks, etc. - often offer bundled/harmful content.

Download and installation processes have to be treated with caution. Hence, it is crucial to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out of all additions. Intrusive adverts look innocuous, yet they redirect to questionable sites (e.g., gambling, adult-dating, pornography, etc.).

If ads and/or redirects of this type are encountered, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - immediately removed. If your computer is already infected with OffersPrimary, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
