Weknow.ac

Advertisement on the Internet have gone aggressive recent time, and people have almost got used to it. Pop-ups are all over the Net – starting from reliable social networks and ending with deserted portals. Some time ago, you've mentioned a few banners per day, and today there is much more of them. People did, after all get that the Internet is the great place to bring in fresh clients, and so did swindlers. They make questionable programs to break into your computer so that it will display to you suspicious, irrelevant advertisement. Our today's subject is a great exhibit of those tools. Ads by Weknow.ac are not for selling things – they are just for you to click on them. If you click on one of those ads, you will appear on a scammers' webpage, offering substandard goods to you. In most cases, there are no goods at all, just an offer to download some unpaid software, which will screw up your laptop and distribute even more advertisement. If you've had enough of it – on this site you’ll see everything you need to eliminate it.

What is Weknow.ac

 

Weknow.ac is a utility, made with the only aim: to show you advertisement. We can't even call it a complete utility, because it is a plain piece of code, able to modify the browser options and adding new strings to the registry. For you to see its modus operandi, we’ll point out its doings one step at a time:

  • If you've picked the "not recommended" way and stopped the installation of adware – you would not be on this page. Subsequent to this, we suppose that you didn’t spot that menu. According to this the installation ran on and Weknow.ac started showing ads to you.
  • When some user finds Weknow.ac and launches the installation, a menu appears, offering two methods of installation. The first option is already selected, and in rare cases you can’t choose another one, because it’s inactive. By picking the suggested method you allow to get each harmful utility from adware bundle, and the second manner allows you choose what exactly you are going to install.
  • The basic Weknow.ac’s goal is fulfilled when it switches the settings of the browser, and after that, it only has to develop protection measures. It adds new lines into the registry and sets system tasks to prevent you from altering browser controls.
  • Next step is to upload the advertising program to a file-sharing portal, along with other suspicious programs. Then it should wait for a credulous person to download it – a guy who won’t read anything and will click OK each time he (or she) could. Naturally, the installation folder is not called Weknow.ac adware – there's another utility in a package. It's the popular one, but installing it, they accept a heap of trash too.
  • The most crucial thing that Weknow.ac does after breaking onto the PC is taking your browser under total control. It places the swindlers' fake website on your search system's place, and does the same thing with the homepage. Then you never see real results for your queries – Weknow.ac will show you only the websites that hackers allow you to see or to click.

That’s what adware penetration looks like. Following the step #5, Weknow.ac is completely ineffective, as all serious functions, including the showing of pop-ups, is performed by swindlers' site. Usually the website looks like Yahoo, Google or Bing, but the results you're getting there are very suspicious. Fraudsters take advantage of a unpaid feature, called Google CSE to put their websites to work, and its principal feature is to bound the search field to a couple webpages. This service is used to show the fake results and make users think that they are true.

How to protect the system

The protection of user's OS is such a thing that cannot be achieved via one miraculous measure. Without a doubt, the antiviral tool will be very helpful, yet you still should do, or even stop doing many things. We’ll list these things below.

  • Update your programs on time, particularly, the operating system and your antiviral utility. The security breaches which viruses use to penetrate the system are getting fixed, so the newer version you have - the more secure your workstation is.
  • You shouldn’t install free programs, and if you aren't ready to stop installing it – download it from an official website.
  • Do not click on aggressive ads, and don’t go to low-quality pages. By that we mean websites which distribute counterfeit programs and movies, adult content, and things like that.
  • There is no real occasion to deactivate your anti-viral program. Particularly if some site suggests you to disable it.

Our tips will help you to ward off adware and most of the other undesired programs. Regardless of that, certain examples of viruses can get into your OS with the help of other techniques, and you have to download a first-rate antivirus to remove them.
