Danger level 7
Type: Adware
Common infection symptoms:
  • Annoying Pop-up's
  • Shows commercial adverts Ad Ad is not a computer infection or a program itself. It is an adware server that can be used by multiple applications to redirect users to specific web pages. If you notice this domain in your browser’s address bar, it probably means that you either opened a website that makes use of the adware server, or you have a program on your PC that makes use of the server. Therefore, to avoid similar advertisements and adware servers, you need to remove all the potential threats from your computer, and then be careful about the websites you visit on a daily basis. If you fail to protect your PC from such intruders, you might eventually suffer from a malware infection.

We have found a few chains of redirects that Ad “works” for. For instance, we know that this adware server can redirect you to, then to,,, and many other adware websites. The point is that the moment these people have your attention, they will make it sure that you will see a lot of commercial ads. After all, their main objective is to sell something. And you are the main customer even if you do not intend to spend a single cent on anything.

As mentioned, Ad might appear on your browser if you have an adware program installed on your computer. Now, where do adware programs come from? Sometimes they have official websites where they favor direct distribution. Sometimes potentially unwanted programs have adware features, and if that is the case, then it is very likely that users download these applications willingly. However, the most common adware distribution method is bundled downloads. It means that users download some program from a third-party source, and that program comes in a third-party installer that bundles several programs together.

Now, you may not be aware of that because no one says just how many programs are in one installer explicitly. Nevertheless, if you download a program from a file-sharing website, you have to keep in mind that there might be more than you have bargained for. In fact, sometimes even official websites bundle additional programs or features in their installers, too. So how do we avoid such programs we neither need nor want? For starters, we have to refrain from downloading apps from unreliable sources. Second, it is important that you read all the steps in the installation wizard because quite often these wizards inform users about the additional apps or features that come along. Users tend to install everything because they simply breeze through the installation without any second thought. As a result, we get to see such adware servers as Ad redirect us to unfamiliar websites.

What happens if we experience a redirection via Ad? Normally, you should be able to close the pop-up window without any difficulty. Adware programs are mostly interested in making some financial profit through advertising, and they do not intend to infect you with anything. However, we have to remember that such apps are very vulnerable to third-party exploitation.

What we mean is that neither Ad nor the program that uses it checks what content they promote. They are satisfied as long as someone generates clicks that lead to making money. The links you click and the websites you land on do not concern adware developers. And that is a shame because it opens a lot of opportunities for cyber criminals to exploit Ad and all the programs associated with it. It could be that eventually, this server will end up being used for malware promotion, and if that happens, you might be in deep trouble.

We need to avoid malware threats at all costs. Although you cannot remove Ad from your computer, you can remove the program that uses the server to promote commercial content. Please scan your PC with a security tool to locate the programs in question. If it is possible, remove them via Control Panel. If not, do not hesitate to invest in a security program that will terminate everything for you automatically. Dealing with such threats might be very frustrating because they are hardly tangible, but it is always better to be safe than sorry.
