How to remove MultiplySearch adware from your operating system

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

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-type apps and browser hijackers collect browsing-related information.

Due to the dubious methods used to proliferate MultiplySearch, it is also classified as a Potentially Unwanted Application (PUA). One of the methods used to distribute this app is via fake Adobe Flash Player updates. Bogus software updaters/installers are used to spread PUAs, Trojans, ransomware and other malware.

Adware enables the placement of pop-ups, banners, coupons and other intrusive ads, typically, on any visited website. The delivered ads significantly diminish the browsing experience, as they overlay web page content and limit browsing speed.

Furthermore, when clicked, intrusive advertisements redirect to dubious/malicious sites and some can even stealthily download/install rogue software (e.g. PUAs). Browser hijackers reassign the homepage, default search engine and new tab/window URLs to the addresses of fake search engines.

To elaborate on how these modifications affect browsing, with a browser hijacker installed, each new browser tab/window opened and search query typed into the URL bar redirects to the promoted address. Rogue search engines are seldom able to generate unique results, and so they tend to redirect to Yahoo, Google, Bing and other genuine sites.

Browser hijackers can restrict/deny access to the browser settings and/or undo any permitted changes made. Therefore, recovering a hijacked browser is impossible without eliminating the software affecting it. Furthermore, most PUAs have data tracking capabilities.

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, the presence of unwanted software on devices can result in system infections, financial loss, serious privacy issues and even identity theft. Therefore, you are strongly advised to remove all suspect applications and browser extensions/plug-ins without delay.

AdjustableProduct and OperativeState are some examples of apps within the adware category. This software usually seems legitimate and offers a broad range of "useful" features, however, the promised functionality is rarely operational. This is true of most PUAs.

The only purpose of these unwanted applications is to generate profit for the developers. Regular users receive no real value and can experience serious problems. PUAs deliver intrusive ad campaigns, modify browsers, cause redirects and track private data.

How did MultiplySearch install on my computer?

PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".

By rushing through download/installation (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.), many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well.

When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages.

How to avoid installation of potentially unwanted applications

All products should be researched before download/installation. You are advised to only use official and verified download channels, since untrusted sources such as unofficial and free file-hosting sites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders offer dangerous files.

When downloading/installing, read the terms, explore all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features, and so on. Intrusive ads may seem normal, however, they can redirect to dubious websites (e.g. gambling, pornography, adult-dating, etc.).

If you encounter ads or redirects of this kind, inspect your 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.
