Weknow.ac

Advertising programs are the main problem of today’s wide Internet, and we think that you’ve fallen a victim of that trash. We’re talking about Weknow.ac adware, the one you’re getting ads from, and also the one that made your computer sluggish, retarded, and unstable. If you think that it’s not a problem – we beg to differ. The thing is that this is a problem, and it will be snowballing until your PC refuses to start and you’ll have either to pay a significant sum of money to recover it or to forget about all the data you have in there and reinstall the system. There is a simple way to avoid that. A couple of ways actually, and they’re described in the following sections of our article. Except that, we will teach you how to protect the system from other advertising programs, and explain to you what Weknow.ac is and how it gets into the system.

What is Weknow.ac

 

Weknow.ac is a kind of program that has the only purpose and can do nothing except serving it. It is adware and it’s only aim is to show ads. As many ads as it can and no matter what. This program gets into the PC and changes the settings of your browser in a way that makes it vulnerable and unstable. Have you mentioned that you have lots of strange and useless programs on your PC lately? It’s because of Weknow.ac! These programs were on the Web all the way, but when they tried to sneak into the system, they were filtered off by your browser, as its default settings are to reject any downloads without your confirmation and to warn you about a suspicious or openly dangerous website. These settings were turned off, but the others were only changed.

We’re talking about the starting page and new tab page. You might have noticed that they’re somehow different from what they have been before, and you’re completely right! The default settings are Google or Yahoo or Bing, but what Weknow.ac set instead of them is not a search engine at all. It’s a dangerous website, created by scammers to look like a search engine and to show you ads. It’s the part that makes Weknow.ac work, and by using it as a search engine, you’re making a problem even worse. To stop this mess you should remove Weknow.ac from your computer for good, and we will help you do that!

How Weknow.ac got into the system, and how to protect your PC from that

Before proceeding to other sections, you have to understand how Weknow.ac infected the system. The method is called bundled installation, and it’s very good for infecting user’s computers. It’s literally perfect: it requires minimum efforts from scammers and makes users liable for the infection. In this method scammers aren’t exploiting any intricate coding – they just use social engineering. They hide viruses in one bundle with a useful program and make you install it. Of course, you won’t read the user agreement where adware’s features are written down, and it’ll go unnoticed. That’s how Weknow.ac penetrated your OS, as well as systems of many other users.

To protect yourself from that you’ll have to follow this simple advice:

  • Don’t turn off your antivirus. This one might look a bit easy, but we mean it. Even if some program asks you to turn it off to make some updates, or to be installed – you ignore those requests.
  • Stop using counterfeit software. Yes, it’s okay that you didn’t pay for a full version of WinRar, but we’re talking about other things, like pirated Word, leaked movie premieres, and other stuff. These pieces of content and software are being distributed through torrents, where no one checks them for viruses, and by that way, adware often crawls into the system.
  • Update all your software in time. This is the easiest part, as most of the antiviruses, browsers, and messengers update automatically, but you shouldn’t ignore when your OS is asking for you to update it. As you might have guessed, updates are fixing the vulnerabilities in the programs, and if the vulnerability gets fixed, it most likely means that someone started to exploit it. It might be your computer that is the next chosen victim, and it’s better to get protected and update everything.

By following our tips, you will significantly increase your system’s security and diminish the chances of infection almost to zero. Now there’s nothing to tell you more about Weknow.ac, and we should start removing it!

How to remove virus

Step 1. Check recently added applications

The first step is to detect and remove malware from your computer. When you go to the "Applications" menu, you will see a complete list of all the programs that are installed on your computer. You should study this list and delete all programs that you do not use, that were installed without your knowledge or who are distrusting you. This way you will get rid of many unwanted programs and viruses.

  • Click Applications in the Finder sidebar
  • Drag unwanted program to the Trash
  • Empty Trash

Step 2. Clean the browser

The second step is cleaning the browser. Most users notice that their computer is infected, only because of browser issues. In most cases, applications for the browser are not needed at all, and if you do not use VPN or applications to block ads, then the application list should be empty. If there are applications in the list, and you do not know where they came from, they should be deleted. Browser applications are a usual form of adware and browser hijackers, so clearing the list you’ll make your web surfing more convenient.

  • Start Safari browser
  • Display a menu of General Safari Settings
  • Reset Safari...
  • Press "Reset"

To clean Google Chrome, reset policies

  • 1) Open your Applications folder, click the Utilities in that folder and double click the "Terminal" application
  • 2) Write next commands to terminal:
    • defaults write com.google.Chrome HomepageIsNewTabPage -bool false
    • defaults write com.google.Chrome NewTabPageLocation -string "https://www.google.com/"
    • defaults write com.google.Chrome HomepageLocation -string "https://www.google.com/"
    • defaults delete com.google.Chrome DefaultSearchProviderSearchURL
    • defaults delete com.google.Chrome DefaultSearchProviderNewTabURL
    • defaults delete com.google.Chrome DefaultSearchProviderName
  • 3) Restart the system

Step 3. Scan the system

The third and last step is the most important. Most malware nowadays has protection mechanisms that interfere with the removal, or allow viruses to recover. However, a decent anti-virus program easily bypasses these mechanisms and removes malicious software once and for all.
