WinArcher “Virus” Removal


In this article we are going to try and help you remove WinArcher “Virus”. Our instructions cover all Windows versions as well as most browsers – Chrome, Firefox, Internet Explorer etc.

WinArcher “Virus” is an Adware-based program that may infect all popular browsers – Firefox, Opera, Explorer, Chrome and others. The infection usually manifests itself when you notice that the pop-up ads you see on your monitor are no longer web-page-hosted, but produced by the browser itself. Basically, that is the main function of all Adware-type products: to display numerous banners, pop-unders, pop-ups, boxes, tabs and other versions of ads. These ads may sometimes correspond to your recent search requests thanks to WinArcher’s ability to match the data from your surfing history to the current ad campaign. This feature of Adware might seem a little too intrusive to some experts and users and that’s why the image of these programs is not completely positive as some of them could be identified as potentially unwanted.

Does a potentially unwanted program equal a virus?

There is no reason for you to panic. WinArcher has never been labeled a virus. None of its functions resemble the ones of any typical malware. Every single program classified as malware is usually capable of crashing your PC, hijacking your system and encoding some of your important data, which is typical for Ransomware, or destroying it. Some malicious programs are even able to spy on you using your own webcam. This is not what you have been experiencing currently. It is true that the number of the produced ads may be ridiculously big and your system may have become slower due to their generation. Despite that, nothing really malicious could come from WinArcher or any other Adware program.

Where can WinArcher be found on the web?

When it comes to probable ways of spreading Adware, there are some very typical places on the Internet where such a program might be lurking. These are spam emails, their attachments (if any), shareware and torrent-spreading web pages and, of course, the usual suspect: any program bundle. If you have used, downloaded or installed anything from the aforementioned list,  that is why your system is now infected.

What is a software bundle?

The typical source of any Adware product is usually a program bundle. These bundles are combinations of various software that gets distributed as one. They may include Adware, browser hijackers and original programs. Programmers create them only for one reason – by combining their own original software with ad-generating software like the one on your system right now and other Adware and hijacker programs, they get both the chance to spread their own software for free, and the opportunity to receive some income from the ads that get displayed later by the ad-producing programs like WinArcher. This famous practice is called pay per click and allows developers to fund their business but to get more users explore their own software at no charge. However, it is not about putting adware together with other programs and trick any user into downloading it. In order to start producing pop-ups and banners, the adware should first be installed.

Installation of program bundles – how to do it right

WinArcher could infect your PC from a bundle if you do not complete the installation process of the program you want from this bundle in the correct way. Adware cannot self-install on your machine, as it is NOT malicious. The feature of the installer that guarantees you the installation of the whole bundle on your PC is usually the quickest, the easiest or the automatic one. Its name usually is Default or Typical. If you want to be able to choose what to incorporate into your system and what to leave behind, forget about this option. On the other hand, if you want to use any original program from any bundle for free but without being annoyed by ads, remember the following names – Advanced and Custom. These are the options of the wizard you should use no matter what you want to install. If you use them, you will get all the necessary info about any bundle in the EUCA and you will get to choose what to put into your PC.
