Removal instructions for PrimaryBuffer adware and the adverts it displays
Written by Tomas Meskauskas on
What kind of application is PrimaryBuffer?
PrimaryBuffer is a rogue application that our research team discovered while investigating new submissions to VirusTotal. After examining this piece of software, we determined that it is adware belonging to be AdLoad malware family.
PrimaryBuffer adware overview
Adware stands for advertising-supported software. Its purpose is to feed users with advertisements. The software achieves this by displaying ads on visited webpages and/or other interfaces.
These adverts predominantly promote online scams, untrustworthy/harmful software, and potential malware. Some of the ads can even execute scripts to perform stealthy downloads/installations upon being clicked.
It must be mentioned that any genuine products or services encountered via these adverts – are most likely endorsed by scammers who abuse their affiliate programs in order to acquire illegitimate commissions.
Advertising-supported software might require specific conditions to run intrusive ad campaigns (e.g., compatible browser/system or user geolocation, visits to particular websites, etc.). However, even if PrimaryBuffer does not deliver advertisements – its presence on a system remains a threat.
AdLoad adware often includes browser hijacker functionalities, but we did not observe any while investigating this application. PrimaryBuffer likely gathers private information.
Advertising-supported software usually collects the following data: browsing and search engine histories, Internet cookies, log-in credentials, personally identifiable details, credit card numbers, etc. This sensitive information can then be sold to third-parties or otherwise abused for profit.
In summary, the presence of software like PrimaryBuffer on devices may result in system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples
DefaultWindow, LauncherIndex, ExpandedBrowser, and InterfaceHelper are just some examples of adware-type apps that we have analyzed recently.
Software within this classification typically appears legitimate and offers a broad range of features. However, the functions seldom work as promised, and in most cases – they do not work at all. Keep in mind that even if an application operates as indicated by its promotional material – that is not a guarantee of either legitimacy or safety.
How did PrimaryBuffer install on my computer?
The bundling marketing tactic – packing ordinary program installation setups with unwanted/malicious additions – is commonly used to distribute adware.
The risk of inadvertently allowing bundled content into the system is increased by downloading from untrustworthy sources (e.g., freeware and third-party sites, P2P sharing networks, etc.) and by treating installation processes with the negligence (e.g., ignoring terms, skipping sections, using "Easy/Quick" settings, etc.).
Additionally, adware can have "official" promotional pages, and it is endorsed on scam websites. Most visitors access such webpages via redirects caused by sites employing rogue advertising networks, misspelled URLs, spam browser notifications, intrusive ads, or installed adware (with the ability to force-open browsers).
Intrusive adverts also proliferate advertising-supported software. When clicked on, some of these advertisements are capable of executing scripts to perform downloads/installations without user consent.
How to avoid installation of adware?
It is essential to research software and download it from official/verified channels. We recommend treating installation processes with caution, e.g., by reading terms, inspecting possible options, using the "Custom" or "Advanced" settings, and opting out of additional apps, extensions, tools, etc.
We also advise being vigilant while browsing since fraudulent and malicious online content usually appears legitimate and harmless. For example, despite their innocuous appearance – intrusive ads redirect to highly questionable websites (e.g., gambling, adult dating, pornography, scam-promoting, etc.).
Should you keep experiencing adverts and/or redirects of this kind, check the device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with PrimaryBuffer, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
