Removing QueueBuffer adware and the advertisements it delivers

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

What is QueueBuffer?

QueueBuffer is a piece of rogue software that our researchers discovered while inspecting new submissions to VirusTotal. Analyzing this app revealed that it operates as adware. Additionally, QueueBuffer belongs to the AdLoad malware family.

QueueBuffer adware

QueueBuffer adware overview

Adware is designed to enable the placement of third-party graphical content (advertisements) on visited websites and/or other interfaces. The ads promote online scams, unreliable/harmful sites and software, and even malware. Some intrusive adverts can execute scripts to make stealthy downloads/installations when clicked on.

Note that any legitimate products encountered through these advertisements are unlikely to be endorsed by their actual developers. Instead, this promotion is undertaken by scammers abusing the products' affiliate programs to acquire illegitimate commissions.

It must be mentioned that advertising-supported software might not deliver ad campaigns if certain conditions are unsuitable, such as incompatible browser/system specs or geolocation, particular websites not being visited, etc. However, even if QueueBuffer does not display adverts - its presence endangers device and user safety regardless.

AdLoad adware often has browser hijacker qualities; however, we did not observe any while analyzing QueueBuffer. However, it is likely that this application collects private information.

Advertising-supported software typically gathers browsing and search engine histories, usernames/passwords, personally identifiable details, financial/banking data, etc. This vulnerable information can then be monetized via sale to third-parties (potentially, cyber criminals).

To summarize, the presence of software like QueueBuffer on devices can result in system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of adware-type applications; ProgressBoostProgramOpen, and SilkTopic are merely a couple of examples.

This software usually looks ordinary and innocuous. Users are lured into download/installation with promises of various "handy" functionalities. However, these features seldom work as advertised, and in most cases - they are utterly nonoperational.

How did QueueBuffer install on my computer?

Adware can have "official" promotional pages, and it is pushed through scam websites. Most users enter these sites via redirects caused by mistyped URLs, webpages that use rogue advertising networks, intrusive ads, spam browser notifications, or installed adware (with browser force-opening abilities).

Additionally, advertising-supported software is distributed by intrusive advertisements. Once clicked on, some of the adverts can execute scripts to perform downloads/installations without user consent. Fake Adobe Flash Player updaters/installers are used in distribution as well.

"Bundling" - packing regular program installation setups with unwanted/malicious supplements - is also used to proliferate adware. Download from untrustworthy sources (e.g., freeware and free file-hosting websites, P2P sharing networks, etc.) and rushed installations increase the risk of allowing bundled content into the system.

How to avoid installation of adware?

We strongly recommend researching software and downloading only from official/verified channels. Furthermore, installation processes must be approached with care. Hence, it is important to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out of all additional apps, tools, features, etc.

Another recommendation is to exercise caution when browsing - as illegitimate and malicious content usually looks harmless. For example, intrusive ads appear harmless yet redirect to highly questionable sites (e.g., gambling, adult-dating, pornography, etc.).

If you experience such advertisements/redirects, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with QueueBuffer, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
