Also Known As: Ads by MultiSet

What is MultiSet?

MultiSet is a Potentially Unwanted Application (PUA) classified as adware. It also has browser hijacker qualities. This app runs intrusive ad campaigns and can cause redirects to fake search engines.

MultiSet adware

MultiSet adware overview

Adware can display pop-ups, banners, surveys, and other intrusive advertisements on visited websites and/or different interfaces. The delivered adverts primarily endorse deceptive and malicious sites. Furthermore, some intrusive ads can download/install software (e.g., PUAs) stealthily - once clicked.

Browser hijackers assign fake search engine addresses as browsers' default and their homepage and new tab/window URLs. Hence, new browser tabs/windows opened and web searches performed via the URL bar - redirect to the promoted address.

These search engines usually cannot generate search results, so they redirect to Google, Yahoo, Bing, and other legitimate ones. This software also employs persistence-ensuring techniques to prevent browser recovery.

Applications like MultiSet typically have data tracking abilities. Information of interest includes - browsing and search engine histories, IP addresses, personally identifiable details, finance-related data, etc. The collected data is monetized through sale to third-parties.

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

Adware in general

AdvancedServices, CoreSource, and AnalogSet are a couple examples of adware. This software and PUAs in general - appear legitimate and promise "useful" features, which are seldom functional. The sole goal of unwanted software is to generate revenue at user expense. Therefore, its presence seriously endangers device and user safety.

How did MultiSet install on my computer?

PUAs are proliferated via downloaders/installers of other programs - this marketing method is called "bundling". Rushed downloads/installations increase the risk of allowing bundled content into the system. Additionally, when clicked - intrusive adverts can make downloads/installations without user consent. PUAs may also have "official" download pages.

How to avoid installation of potentially unwanted applications?

It is strongly recommended to research software and download it from official/verified sources. Dubious download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc. - can offer bundled content.

When downloading/installing, it is advised to read terms, explore available options, and use the "Custom/Advanced" settings to opt-out from all supplements. With the abundance of scams and harmful ads online, it is important to exercise caution when browsing.

Intrusive advertisements appear innocuous yet redirect to questionable websites (e.g., gambling, pornography, etc.). In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with MultiSet, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
