How to remove PracticalSystem adware

What is PracticalSystem?

PracticalSystem is classified as adware and a browser hijacker: this app serves advertisements and promotes fake search engines (0yrvtrh.com and search.dominantmethod.com) by changing certain browser settings. PracticalSystem can also read sensitive information from websites.

It is categorized as a potentially unwanted application (PUA), since users often download and install it inadvertently.

Research shows that PracticalSystem changes browser settings on Chrome browser to search.dominantmethod.com, and on Safari browsers, to 0yrvtrh.com. These are fake search engines that provide results generated by Yahoo (the site simply redirect users to search.yahoo.com).

This is why they are classified as fake search engines. Browser hijackers prevent removal of the fake search engine address from the browser settings until the app that promotes it is no longer installed.

Therefore, 0yrvtrh.com and search.dominantmethod.com can be removed from settings of a browser hijacked by PracticalSystem only when this PUA is removed. This PUA can also collect information such as passwords, telephone numbers, credit card details and other sensitive information.

These details could be misused to steal accounts and identities, and make fraudulent purchases and transactions. The details could be sold to third parties (potentially, cyber criminals) and/or misused for other malicious purposes. Like most apps of this type, PracticalSystem serve advertisements.

Commonly, these applications serve advertisements designed to promote/open dubious websites and even cause unwanted downloads and installations. Some examples of ads displayed by PracticalSystem are coupons, banners, pop-ups, and surveys. These are the reasons why PracticalSystem should never be installed - remove it from browsers and computers immediately.

PracticalSystem is very similar to TypeConsole, DigitalEnviroment and TypicalOperation and many other applications. Generally, these apps serve ads, collect various data and hijack browsers. Even if they are advertised as useful and legitimate, most are designed only to generate revenue for the developers and are useless to regular users.

How did PracticalSystem install on my computer?

Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software.

This distribution method is known as "bundling". Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.

In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.

How to avoid installation of potentially unwanted applications

Download software and files from official websites and via direct links. It is not safe to use torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, unofficial websites or other sources of this kind. Avoid third party installers. Check "Advanced", "Custom" and other settings, and decline offers to download or install unwanted software.

Do not click ads that are displayed on dubious websites, since they can open other untrusted websites or even cause unwanted downloads and installations. Remove any unwanted, suspicious applications (extensions, add-ons, and plug-ins) that are installed on the browser.

The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with PracticalSystem, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
