Primosearch.com Redirect

Also Known As: primosearch.com pop-up
Type: Adware
Damage level: Medium

What is primosearch.com?

Identical to deloton.com, trackingclick.com, rosetheet.com, and many others, primosearch.com is a rogue website designed to redirect to a number of other suspicious sites. Research shows that users are redirected to primosearch.com by potentially unwanted programs (PUPs).

These rogue programs usually infiltrate systems without permission, or trick users to install by falsely claiming to provide "useful features". Following infiltration, PUPs cause unwanted redirects, diminish system performance, deliver malicious ads, and collect user-system information.

primosearch.com adware

Potentially unwanted programs randomly open new browser tabs/windows and redirect to primosearch.com, which, in turn, causes several (usually 2 or 3) successive redirects to suspicious sites. There is a high probability that these sites will contain malicious content. Therefore, redirects to primosearch.com can result in high-risk computer infections.

In addition, PUPs deliver 'malvertising' ads (such as coupons, pop-ups, banners, etc.) To achieve this, developers employ various tools that enable placement of third party graphical content on any site. Therefore, displayed ads often conceal visited website content, significantly diminishing the browsing experience.

When clicked, these ads can lead to malicious websites and/or execute scripts that download and install malware. Clicking them can also result in various computer infections. Be aware that some PUPs run various background processes (such as mining cryptocurrency).

By stealthily misusing system resources, potentially unwanted programs significantly diminish overall computer performance. Most potentially unwanted programs continually record user-system information that might be personally identifiable. Developers sell this information to third parties (mostly for marketing purposes).

Thus, potentially unwanted programs pose a direct threat to your privacy and Internet browsing safety. We strongly recommend that you eliminate all PUPs immediately.

There are hundreds of potentially unwanted programs, all of which are virtually identical. Most offer various "useful features" (for example, anti-virus, download tools, audio/video players, etc.), however, these claims are merely attempts to trick users to install. The only purpose of potentially unwanted programs is to generate revenue for the developers.

In fact, only a small percentage of PUPs enable the functionality promised - most are useless. Rather than providing any value for regular users, they promote malicious websites (including fake search engines), deliver malvertising ads, stealthily run unwanted processes, and collect user-system information.

How did adware install on my computer?

Research shows that some PUPs have official download websites, however, most are distributed using the aforementioned malicious ads, together with a deceptive marketing method called "bundling". Therefore, PUPs often infiltrate systems without permission, or users install them inadvertently without their consent.

Bundling is stealth installation of third party software together with regular (mostly free) software.

Developers hide bundled programs within various sections of the download/installation processes - they do not properly disclose this information. Many users rush these processes, skip steps, click ads, thus exposing their systems to risk of various infections and compromising their privacy.

How to avoid installation of potentially unwanted applications?

Poor knowledge and careless behavior are the main reasons for computer infections. The key to computer safety is caution. Therefore, be cautious when downloading/installing software and browsing the Internet in general. Download your software from official sources only and (if possible) using a direct download link.

Third party download/installation tools are monetized using the bundling method (they promote other software). Therefore, using these tools is very risky. When downloading/installing, carefully analyze each step (especially the "Custom/Advanced" options) and cancel all additionally-included programs.

Note that malicious ads usually appear genuine (criminals invest a great deal of resources into ad design). Therefore, it is difficult to determine if they originate from the visited (legitimate) website.

These ads are distinguishable by their redirects - they usually lead to gambling, pornography, adult dating, survey, and other suspicious websites. If you encounter such ads, uninstall all suspicious programs and browser extensions.
