How to remove (uninstall) ContentStyles

Do you notice aggressive banners on your favorite websites that come from the ContentStyles search? Have you noticed the presence of ContentStyles somewhere else in the system? If those things are true – the PC is infested with adware, and this entry can assist you in removing it.


What is ContentStyles

Immediately after the penetration, ContentStyles changes the settings of your browsers. That's its only aim, because the essential part of this adware is the “innovative search” to which you're being redirected. So, adware changes your default homepage, as well as your favorite search engine and places the fake webpage instead of them. Now, instead of searching via the reliable Bing, Google, Yahoo or whatever search you're used to – you will surf the Internet through the miserable scammers' website, giving away suspicious websites ads pop-up windows and other suchlike trash. ContentStyles also substitutes the controls of browser icons so that in case you return the normal settings, you will see the scammers’ search in the starting tab.

If you have already bothered to uninstall this adware, you could notice that it recovers, no matter how many times you erased it. It happens thanks to the virus' defensive algorithms, and we can explain to you how they work:

  • The first method of security is to make a scheduled task on the restoration of the adware after its deletion. Such tasks aren’t often used by regular computer operators, so ContentStyles simply creates a task to see if it is working, and if it isn't – to download and set it again. That task is being executed after each reboot, and that’s why ContentStyles is so hard to remove.
  • Another manner is pretty much like the previous one, but it employs the system registry and not the Scheduled Tasks service. You must clear the registry to beat this manner, but it is a very hard thing for a newbie. All other registry items are very important, and by deleting any of them, you can cause serious damage to the OS.

The tool that shows ads is called ContentStyles, and it is an advertising utility. ContentStyles can't do anything good, as it was made to achieve only one purpose: to irritate you. Well, your annoyance isn’t its real task, but you'll be mad in any case while ContentStyles does its job – displays ads. It infects the device, it modifies the controls of the browser and shows you lots of links, to ensure that they've drawn your attention. Scammers receive a little money for every click you're making, and now you see why the links keep appearing: it’s a gold mine. In the coming paragraphs, we’ll tell you in which manner the virus got onto the PC and how it might be defended against similar viruses. If you are not interested and just want to delete the virus as soon as possible – skip the following sections and look at the removal guide.


How ContentStyles was installed in the system

To make it simple, we’ll depict the whole process from the start. 99% of the advertising programs are replicas of each other, repeated thousands of times and passed to third-grade hackers with minor changes made. One of the suchlike dudes got this particular copy on an underground auction, tuned it and put it on file-exchanging services all over the Web. That’s where you found it, right? Wait, are you sure that you didn’t search for adware to drive you crazy? Or, you wanted some screwing-it-all-up tool for the machine, and got a useful link to ContentStyles downloader? Still wrong? OK, then, it was another program that is actually good. Some free tool created by a not-so-famous developer, or a hacked version of some well-known program you just don't want to buy.

The method is called “affiliate installation”, and it's based on that fraudsters unite the installers of a few viruses and one useful software into one package. The principal peculiarity of this bundle is that they call it by the name of a helpful utility, and you can't know its content before the installation begins. On some of the steps, you see a proposal to download additional tools, with the required checkmarks placed and the easiest decision is to install them and move on. We suppose that you did so, as you're reading this entry. It might have been slightly different: they might have done this through the “installation manners”. In most cases, the expert installation method gives you the ability to pick a directory for a utility to be established, which extra modules do you need, and which you don’t. In ContentStyles's case, picking the easy installation means that you admit all the adware from the package into the machine.
