This page aims to help you remove System Security Tool. These System Security Tool removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Before we start on the removal guide, it is a good idea to have a brief look at what System Security Tool is.

What is System Security Tool?

System Security Tool is considered an adware – a piece of programming code that is non-malicious and does not seek to harm the computer in which it resides. Do note that an adware is not a virus. A virus is a piece of programming code that is malicious and will harm the computer in which it resides. However, just because it is non-malicious, does not immediately mean that you should remove it.

There are still some negative side-effects to System Security Tool. Amongst which are feelings of irritation, annoyance, frustration and anger, all of which will accumulate to heighten your stress level. These feelings are evoked after you have been confronted with an incessant amount of ads that appear at critical times – when you are in a rush or in the midst of doing something important. Also, the processes connected to System Security Tool may also lead to slowing down of your computer’s functioning which contributes to your feeling of frustration as well.

How does System Security Tool work?

Adware programs are often designed in a way to be able to track down all your browsing patterns and history, favourites and bookmarks. From the gathered data, they may then create convincing and tempting ads that are out to entice you to click on them. These ads may appear in a variety of different forms. They may feature anything from coupons and deals to claims that you have won a lottery. Regardless of the form the ads take or the messages used, do bear in mind at all times not to be lured into clicking on them. These ads may be generated by System Security Tool and may be potentially misleading.

Probably the best case scenario when dealing with adware applications is for you to be redirected to a page that has been gathered from your history records, featuring the so-called ‘deals’ which you may have previously seen. You might also be directed to a third-party’s pay-per-click site that helps its creators earn some extra income when entered. One of the more dubious sites that you might possibly be directed to is a website doubling up as a portal for other adware applications that may gain access and enter into your computer without your knowledge. Other possible dubious sites might be those that prompt you to download a program. The program in question may be potentially full of security loopholes and may become a source of security threats in the future.

How did my computer get infected by System Security Tool?

Infection can happen via a lot of ways, one of which, as stated above, is by visiting those sites that double up as a portal for additional adware.

Another more even more common way in which computers get infected is through downloading one of the many free and perfectly legal programs that are available on the Internet. These programs usually have an adware, or two, being bundled together with them as a set ready for downloading. Thus, when downloading these said programs, you unwittingly download the adware as well.

However, in these cases, all hope is not lost! Adware is unable to carry out its function until it is being installed. Therefore, you should take extra care and caution during the installation process. Instead of opting for “Automatic Installation”, go for the “Custom Installation”. This is where you are able to check through all the files that are to be installed onto your computer. When looking through the files, uncheck any whose names are unfamiliar, strange or suspicious to you and you should be fine.
