How to remove KeyStream Ads
What is KeyStream:
Threat Classification: PUP/adware
KeyStream claims to be an useful browser application, but our security researchers have warned us about it, that it has been classified as an adware and a PUP (Potentially Unwanted Program), by the majority of the security researchers on the Internet, including our security team. KeyStream is capable of infiltrating systems without asking for owners permission or consent. When it gets active, the browser extension, starts showing all kinds of irritating web ads on almost every web page you visit. Please note, that the ads, shown by the KeyStream are NOT SAFE and you should avoid clicking them. If your browser starts showing ads “by KeyStream Ads” , “Ads by KeyStream”, “KeyStream Ads”, “Ad by KeyStream”, “Powered by KeyStream”, “Brought by KeyStream” or “Brought to you by KeyStream” – you should consider your computer infected by the KeyStream malware. The adware works just fine with all the well-known web browsers like Internet Explorer, Mozilla Firefox and Google Chrome.
Generally, users that have it installed on their systems might experience various pop-up or pop-under ads, coupon boxes, banners, search suggestion windows, sponsored link advertisements or other commercials, displayed on popular web pages. The victim’s search results are compromised as well. Usually the search results are full of 3rd party advertising and SPAM.
KeyStream is usually bundled with some other free ad-supported software products and is being installed by default, when the user accepts the EULA, while performing an express/quick or recommended installation of that software bundle. The possible distribution of KeyStream varies but is not limited to – installing third-party toolbars, free software products, video editing software, codecs, downloading e-mail attachments, clicking on not safe ads or banners etc.
The main goal of KeyStream is to generate as much web traffic as possible, that could easily be monetized via one of the many online marketing platforms. Please note, that the creators of that or similar adware collect private information from your computer, that might be used to track your browsing habits, IP addresses, Bookmarks, Usernames, Passwords and even financial information, however often they collect much more than just that. That’s why this infection should not be left unattended, and needs to be terminated immediately, as it presents a serious threat to your online, personal and financial safety.
!!! Please note, that these infections could potentially bring up other malware to your computer and even cause a loss of data. Please do not underestimate such threats.
