What is PrimaryServiceSearch

PrimaryServiceSearch is an adware application promoted via fake Adobe Flash Player installers. Although adware is usually categorized as unwanted software (not malware), its presence can still cause enough damage to the privacy and integrity of users’ computers. Upon installation, apps with advertising abilities can start inserting dubious ads on various websites using “virtual layers”. The promoted content is usually designed to spread online scams, phishing pages, adult websites, fake software installers, or even malware infections. Software like PrimaryServiceSearch may also be capable of tracking browser-related information (e.g., history, IP-addresses, geolocations, passwords, etc.) and can then share it with third parties for revenue purposes. Letting PrimaryServiceSearch run on your Mac or other operating systems can be dangerous for your data and system as well. This is why we advise you to use our instructions below and remove it from your computer – as soon as possible. Remove it from Safari, Google Chrome, and Mozilla Firefox browsers in our guide below.

How PrimaryServiceSearch infected your computer

As mentioned, PrimaryServiceSearch is mainly distributed through fake Flash Player installers. Deceptive pages attempt to lure inexperienced users into downloading forged software by claiming their system is outdated or lacks some software. Such pages are usually visited inadvertently – after clicking on some dubious ads, buttons, or links on third-party websites. Infiltrations of unwanted programs can also occur via third-party software installers. As a rule, it is cracked or pirated program installers that get downloaded from Peer-to-Peer (torrent) pages. Creators of unofficial installers often seek monetary gains by collaborating with other dubious vendors and helping them share their software. Such dubious software may be included inside the installer and presented as an additional offer. However, because many users neglect reading the “Terms & Conditions” and also do not check all settings of the installation (“Custom”, “Advanced”, etc.), they end up infected with unwanted software eventually. Sometimes the installer may offer to choose between “Recommended” or “Manual” types of installations, which could be your case as well. In other instances, it may also be that information about third-party offers will not be disclosed at all, meaning it is impossible to prevent its installation.
