You keep seeing “Ads by DealStream,” “ DealStream ads” and similar pop-up ads on your PC screen all the time? Are you wondering what is the problem? Do you want to see these ads? Alternatively, maybe you do wish to eliminate them for good? Please read this report to find out what are the cons of this program – because there hardly are any pros.

DealStream – why it is a bad program?

DealStream pretends to be an amazing shopping assistant app that is supposed to enhance user’s shopping experience. In reality, it is a free program for users, but it gains revenue from the third-party sponsors. As a result, users can get this app for free, but then they become marionettes to generate income for the developers of DealStream. How? The answer is simple.

DealStream is a potentially unwanted program (PUP) that is mostly spread in a shady computer programs’ distribution way, which is called bundling. It means that this application can be attached to any free program – and if the computer user downloads such program and installs it carelessly, he/she may end up with DealStream on their system. This is where DealStream begins to initiate its arbitrary activities. Once landed on the victim’s computer, it places its files in the Windows Registry. Then it installs its components to each web browser that is installed on the victim’s computer. Therefore, it may affect Opera, Safari, Mozilla Firefox and Internet Explorer. On the official page of DealStream PUP, it suggests to install an extension to Google Chrome only – but it is because Google Chrome is one of the most popular Internet browsers at the moment.

Examples of

Once this rogue application attaches itself to the Internet browsers, it starts to track victim’s activity on the web – so it means it may reveal your browsing history, downloads, bookmarks, IP address and even search queries to its third-party partners. Also, this information can be used to deliver targeted ads for you. DealStream is going to send you various ads in a form of banners, in-text links, and pop-ups; however, even if these ads look appealing, you should never click on such ads. They are sponsored by unreliable sources, and you might get redirected to suspicious websites that can be dangerous. We recommend you to remove DealStream with an anti-spyware program – like Reimage.

DealStream distribution methods:

As we have already mentioned, DealStream virus can be spread via the bundling method. The developers of DealStream make deals with other free software developers and pay money for them in order to be able to bundle DealStream with other free applications. As a result, software bundles are being built. This is why you have to be very careful whenever you decide to download freeware or shareware from the Internet. We recommend downloading programs only from trustworthy websites. It is also a good idea to read feedback about the program and the website that provides the download link – you can find out whether you should download the program from that or from another website. However, it is even possible to reject optional applications like Deal Stream even if you DID download a bundled software pack. All you have to do is to choose “advanced” or “custom” installation method and deselect suggestions to install extra programs. If you think that Deal Stream has already infiltrated your system, continue to the page 2 to find out how to remove it.
