How to Remove Site Trust Checker

A computer is probably infected with Site Trust Checker adware if the homepage and search engine use an undesirable URL. This homepage hijacker can enter the computer through a number of methods and deftly avoids security measures as well as user consent. Site Trust Checker’s creators use a variety of distribution methods to spread the malicious code that infects the browser, earning it the moniker “potentially unwanted program” (PUP).

Site Trust Checker Distribution Scheme

As previously indicated, the perpetrators of this malicious browser extension employ a variety of strategies to disseminate Site Trust Checker broadly online. Here are a few of the most popular distribution plans:

Malicious Software Installer

Attackers are confident that target victims may unintentionally install the adware when the program setup is carried out since they have embedded Site Trust Checker inside various software installers. While only one instance is visible to users, this approach can execute multiple simultaneous installation processes. In addition to freeware, it was discovered that Site Trust Checker is frequently packaged with serial key generators and cracked software.

Fake Software Update

Another method used by attackers to distribute Site Trust Checker is through a phony software update. In order to trick online users into downloading the undesirable program, this is the current trend. The technique uses a pop-up ad that appears to be a system alert. It is claimed to identify problems brought on by out-of-date software and advise web users to get the recommended software update right away. If the user falls for this ploy, Site Trust Checker will have access to the computer.

Misleading Pop-up Ads

Pop-up advertising is also used in this approach. The strategy for this one, however, is much more aggressive because of the persistent display of advertisements touting Site Trust Checker as a useful browser plugin that improves web users’ online browsing and search experiences. These advertisements may appear on dubious websites like,,, and many more.

Site Trust Checker is a browser hijacker

When Site Trust Checker is installed, it immediately changes the homepage and sets an unwanted search engine as the default. As a result, whenever that web user conducts an online search, the request is forwarded to an unwanted search engine. The goal of this redirect is to gather important data from each online user’s search query.

Users who utilize Site Trust Checker as their default search engine may never receive the same helpful results they did before the infection, even if a legitimate search engine is still in control. Site Trust Checker’s new and faulty search engine frequently has paid links and other harmful advertisements on the search result page.

To sum up, Site Trust Checker is a harmful browser extension that needs to be removed right away in order to return the browser to its prior state of efficient operation.

  1. If I could delete it by just going to the add-on settings, I wouldn’t be looking for the solution. Unfortunately, it keeps shutting down the browser after each download AND when you press to delete the add-on. WTH is that about, and how can one fix it?
