This page aims to help you remove WinArcher “Virus”. These WinArcher “Virus” removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Welcome to the WinArcher “Virus” removal guide. On this page, you are going to learn how to effectively remove the annoying activity of this program and clean your screen from the intrusive ads that have been flooding you lately. Before you scroll down to the removal instructions, however, we suggest you to familiarize yourself with the specifics of this type of programs, known as adware. Such programs are famous for displaying different pop-ups, banners, ads, links and messages on the users screen and usually fall in the category of ads-generating software (in short – adware). Widely used as an online advertising tool, adware-like pieces of software can be found almost everywhere on the web, and in the next lines, you will learn about the most common web locations they are spread on and how to stop them from getting installed on your system in the future. In case you are concerned about your safety, here we are going to clarify the major differences between adware and malware applications and the risks they may hide. Just read the next lines if you want to know more.

In case you wish to know how you ended up with WinArcher, here are the possible ways:

Some of the most common ways you may get a program like WinArcher is through spam emails, direct downloads, third party installation wizards, torrents, free add-ons or applications, file sharing websites or open source download platforms. It is good to know that a common practice of the software developers usually is to include adware in the installation packages of applications they give away for free. And since users love free stuff, this is the most probable way they may get WinArcher, especially if they recently downloaded and installed some new and free software on their system.

To prevent adware, pick smart.

It would be quite unrealistic to say that you should avoid getting free software or visiting the above-described web locations, especially in this digitized world where data flows freely everywhere. However, in case you want to minimize the chances of getting adware, it is a good idea to always inform yourself about what software you are downloading and what it has in the bundle. To do so, you can read the EULA before proceeding with any new installation. It would give you a detailed explanation about what is bundled within a given package. However, to prevent the actual installation of adware or other potentially unwanted programs, you should click the advanced/custom option in the setup and manually choose which programs to install and which not. If you just go for the standard or quick install, you will overlook the bundled apps and they would get installed automatically without your consent.

Is WinArcher a “Virus”??

No, not really. Let us elaborate! There is no need to panic if you detect an adware application like WinArcher on your computer. Even though some websites may refer to it as a virus or malicious application, such programs generally are not considered by experts as a real threat to your security. Unlike malware, like the infamous Ransomware or Trojans, adware does not contain harmful scripts, programmed to corrupt the users’ system. However, this type of ads-generating applications may often be referred to as potentially unwanted due to the aggressive way they display their ads and the possibly undesired changes they may impose on the browser settings.

Should you remove WinArcher?

Considered as one of the harmless applications that could be found on the web, WinArcher may still perform some undesired activities which can prompt users to seek ways to uninstall this program. Very often, programs of this type collect information about the users’ online habits. They may keep track of the websites you visit, the topics you are interested in, based on your searches, the locations you log in from, the things you like and share on social media and all sorts of browser-related data. This is done with the idea to increase the chance of you clicking on some ads if they are optimized according to your interests. A possible issue that may lead to misuse of this information is that the data is transmitted to the adware developers and could be sold to third parties. It is not known how safe they keep it or how it may be used, therefore, some users may wish to uninstall the adware in order to stop it from tracking them.

Another concerning thing, which WinArcher may indirectly expose you to is being redirected to insecure web locations. When dozens of ads appear every now and then and you happen to click on them, be it on purpose or by mistake, you may end up on an unknown web page or be redirected to websites, which may hide potential threats such as different viruses, Trojan horses, and even Ransomware. Although this doesn’t happen very often, it is not excluded that some criminal actors may release a fake ad with malicious payload among the others. This hazardous risk is really not worth it, therefore, we recommend removing the unwanted software to avoid any such scenario. You can easily do that with the help of the instructions provided in the removal guide below. Should you need any help, just let us know in the comment section.
