Step 3. Remove from browsers

The most essential attribute of We Know adware is that its danger towards your device steepens respectively to the time it dwells within it. We Know's first aim is to show advertising materials, and by doing it, it changes the options of your browsers, including specific security settings, making your browser soft against all kinds of the incoming threats. All these websites that were marked suspicious are now free to access. All those direct download links which needed your approval will just instantly put a virus into your system in a moment after you make a click. We could keep complaining about this for weeks, but long story short - let’s say that the sooner you will delete We Know – the better.


Clearing the browser is just as important as cleaning the system, since the browser is the home of most adware, such as adware, browser hijackers and browser toolbars. Often, if you do not use the browser professionally, then the application list must contain one or two applications or even be empty. Otherwise - carefully review the list and delete all applications that look questionable or if you do not remember how you installed them.

Google Chrome

1) Open your Terminal application: type "Terminal" into your spotlight search and hit return

2) Copy and paste each of these commands into the terminal application window.

What virus is

This thing isn't even a full-fledged program. It’s just a foothold for each virus that swindlers may want to soil user's customer's PC with. While executing the functions of an advertising program, it had changed the reputable search engine and starting page to force you to attend fraudsters’ “search engine” that is about to drown you in ads. Unfortunately, it has many even more hazardous roles:


  • Malware is capable of saving the data on the set of user's device, operator's search queries, the attended sites and lots of other things. This information is highly valuable for many parties, specifically if somebody sells it by quantities. That's the cause for fraudsters to get as many machines contaminated as they can, notwithstanding 95% of them will be cleared of infection sooner or later.
  • We Know may work as a keylogger, saving every single character typed with the help victim's keyboard. Fraudsters are generally interested in passwords to bank services, mail, important websites, social networks, etc.
  • Virus may be applied to perform spying functions, with the help of your web-camera or in any other way.


We strongly doubt that We Know carries out these functions at the moment, yet it's able to do it, and by neglecting it, you are making it happen.



We’ve explained to you the very important things about We Know’s primary purpose, but it has another function that you'd better know about. In due course, We Know starts engaging malicious utilities into your computer. We are sure that you’ve encountered the clogged device no fewer than one time: the PC that hardly turns on, and launches every program for a minute or something. It's slow and unstable owing to a heap of undesired programs working in the background continuously. Do you want your PC to become like this? We beg to differ.


To grasp the techniques to eliminate We Know, you need to learn how it functions. The dangerous tools that penetrated your system aren’t related to We Know anyhow, yet it made the contamination possible by switching the anti-viral algorithms off. The longer We Know lives in your OS, the worse this situation is. The single technique to clear this mess is to uninstall We Know for good.


To infect your computer, adware utilizes the sponsored installation method. That is to say, you have helped to contaminate while it worked on penetrating your workstation. The algorithm is super common. Swindlers make a bundle of a few viruses and a sole reliable tool, to attract users’ attention, and trick them into downloading it. The installation procedure is modified so that you might either install the whole package, or call it off, but there is no chance to install just the decent utility. The thing is that most victims don’t even pay attention to it – they promptly accept everything and move further. To shield your system against this way, you have to think of the odds of infection each time you install a toll-free utility.
