How to Remove DealStream? (Useful Removal Guide)

What is DealStream?

DealStream pretends to be a legit and useful application which can help computer users surf the Internet effectively, safely and quickly. However, the unknown program messes up the target computer greatly. At first, it can get into your system without asking for any permission. Then the malware installs itself as well as suspicious files stealthily. It activates itself on system boot-up to carry out malicious activities. When running in the background, DealStream takes up most of the system resources. This slows down the whole PC performance seriously. Your Internet connection could shut down at times.

In addition, DealStream adds new add-ons to IE, Firefox and Chrome secretly. It generates numerous ads such as coupons, deals, savings and offers. Meanwhile, the pesky program is able to trace your browsing activities and online history. It gathers your net surfing habits and displays attracting pop-ups. However, it’s not advisable to click those DealStream ads. They may contain other threats which can further destroy the computer. Even, malicious programs could be dropped automatically on the system. On the other hand, the pest may collect your personal information and sell for illegal purposes. Therefore, to well protect both your machine and the private data, you’d better remove DealStream once it appears.

What Would DealStream Do on Your Computer?

This software boasts itself to be a favorable browsing tool that can add additional features on browsers so users will be able to customize and enhance the interaction with the websites they visit. If you install this software, you can view the web page with rich imagery, text and other vivid content during your browsing experience. These functionalities are achieved by using browser extension, tools, social media, applications, coupons and other various services. However, as far as I can see DealStream does more harm than good. When you install this program, you grant it the authority to adjust some browser settings automatically for optimizing its performance without further notification. It is really exasperating and intrusive when your own settings get changed without your knowledge. It is acceptable when the software updates to the latest version, add new features or fix bugs. Such changes will only bring users a better experience when using it and will not have much impact on browser; however, the changes hap
pen not only on the browser extension, but also on other browser settings like homepage, new tab and even the content displayed on the page you open.

These aggressive changes will seriously interfere with users’ online activities for the sake of gaining interest. DealStream is a scampish adware in nature, so it can hijack the browser to load strange sites or new tabs associated with promotional ads. It acts somewhat like a browser hijacker and casually reroutes users’ intended visit to its predefined pages which usually are injected with lots of ads or are promoting some form of software that actually is another malware. When users are viewing content on the web page, this malware may pop up various types of ads and other irritating material on the screen all at once so users will be unable to access the Internet smoothly as usual. If you simply think the malicious browser extension can only display unwanted pop-up windows or tabs at its best, you are underestimating its capacity.

The invasive ads can be seen anywhere on your screen with the excuse that it is sponsored by advertisers. There is plenty of software backed by advertising in app store because developing program needs money while computer users are prone to using software free of charge. Inserting advertisements into software is a common and main method that software developers earn revenue to pay all expenses. Unlike other legitimate and popular freeware, the way that DealStream places ads are not that clear and decent. It shows ads in an unpleasant and cunning way that makes users feel deceived and feel they are fooled. By default, users agree to receive and see ads in the browser as long as they start to use this software, but users will not be informed about this term unless they initiatively read the Privacy Policy and End User License Agreement.

Once DealStream is installed on users’ devices, it gains the ability to insert a barrage of ads to each web page you arrive at through its browser plug-ins or add-ons. The ads can be displayed in various different forms such as banner ads, pop-ups/pop-unders, text ads, interstitial ads and all that. Even simply any of them can be offensive to web users, not to mention how annoying it could be if you see several unwanted ads in the same page to cover the content that you required for. The ads can also be seen in your search results. It would be a rather arduous process for users to get accurate search results as they could be redirected to a totally strange website even if they click on the right URL of the site they mean to go. It is hard to close the pop-up windows or tabs carrying with ads sometimes. For increasing the web traffic of its website and other sponsors, the advertisers may use trick to get users click on the ads. When users are trying to close the ads by clicking the button suggesting Close or X, it m
ay trigger more pop-ups or even malware downloads. In addition, those unsolicited pages are likely to be complicit with other insidious cyber infection which may damage users’ computers severely.

The ads from DealStream or other third party could be a serious privacy violation as they will use users’ browsing history, cookies, previous search activity and any other users’ interaction with Internet to show users ads based on their preferences. They collect and track users’ online behaviors and data like location and interests to attract users’ attention whereas users’ personal data could also be revealed and shared with third party. No one can guarantee that it is safe to click on the ads when the ads are powered by unknown third party. According to the terms of DealStream, they allow the services including advertising and marketing provided by third party for the purpose of helping they manage this software and provide other services, but they are not responsible for identifying the risks that might be brought by any third party providing products, ads, links or any service in DealStream. In other word, users should take their own risks when click on unfamiliar links. The third party is not under their control.
