How to remove MultiplySearch adware from Mac?

What is MultiplySearch?

MultiplySearch is an adware-type application with browser hijacker traits. It operates by running intrusive advertisement campaigns, making modifications to browser settings and promoting fake search engines. Additionally, most adware-types and browser hijackers collect browsing-related information. Due to the dubious methods used to proliferate MultiplySearch, it is also classified as a PUA (Potentially Unwanted Application). One of the methods used to distribute this app is via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers are used to spread not only PUAs but trojans, ransomware and other malware as well.

MultiplySearch adware distributed via fake Adobe Flash Player updater/installer

Adware enables the placement of pop-ups, banners, coupons and other intrusive ads - typically, on any visited website. The delivered adverts seriously diminish the browsing quality, as they overlay page content and limit the browsing speed. Furthermore, upon being clicked, intrusive advertisements redirect to unreliable/malicious sites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers reassign browsers' homepage, default search engine and new tab/window URLs - to the addresses of fake web searchers. To elaborate how these modifications affect browsing, then with a browser hijacker installed: every new browser tab/window opened and search query typed into the URL bar - redirect to the promoted address. Illegitimate search engines are seldom able to generate search results, so they tend to redirect to Yahoo, Google, Bing and other genuine ones. Browser hijackers can restrict/deny access to the browser's settings and/or undo any permitted changes made. Hence, recovering a hijacked browser is impossible without eliminating the software affecting it. What is more, most PUAs have data tracking abilities. They can record browsing activity (visited URLs, viewed pages, searched queries, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details). This vulnerable data is then shared with and/or sold to third parties (potentially, cyber criminals). To summarize, presence of unwanted software on devices can result in system infections, financial losses, severe privacy issues and even identity theft. Therefore, it is strongly advised to remove all suspect applications and browser extensions/plug-ins without delay.

AdjustableProductOperativeState and OperativeState are a couple examples of apps within the adware category. This software usually appears legitimate and offers a broad range of "useful" features. However, the promised functionalities are rarely operational. This is true of practically all PUAs. The only goal of unwanted applications is to generate profit 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 track private data.

How did MultiplySearch install on my computer?

PUAs are proliferated via download/installation setups of other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, using "Quick/Express" settings, etc.) - users can unintentionally allow bundled content into their devices. Some PUAs have "official" download webpages. Once clicked on, intrusive advertisements can execute scripts to download/install PUAs without user consent.

How to avoid installation of potentially unwanted applications?

All products should be researched before download/installation. It is recommended to only use official and verified download channels. Since untrustworthy sources, like: unofficial and free file-hosting sites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders. When downloading/installing, it is advised to read terms, explore all possible options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features, and so on. Intrusive adverts appear ordinary, however they redirect to dubious websites (e.g. gambling, pornography, adult-dating, etc.). In case of encounters with ads and/or redirects of this kind, users must inspect their devices and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with MultiplySearch, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
