Ads by Istreamer

What is Istreamer?

The application, Istreamer, claims to improve Internet browsing by rendering various interactive content such as graphics, text, etc. By delivering these fake promises, Istreamer attempts to trick users into believing that it is a legitimate and useful app. In fact, Istreamer is categorized as adware and a potentially unwanted program (PUP).

One of the main reasons for these negative associations is stealth installation - this app infiltrates systems without users' permission. Furthermore, it generate intrusive online advertisements and tracks Internet browsing activity.

Istreamer adware displays coupon, price comparison, banner, in-text, pop-up, pop-under, and other similar ads. None originate from the visited sites and conceal underlying content, thereby significantly diminishing the Internet browsing experience, since users are forced to avoid clicking them.

Furthermore, although most of these advertisements redirect to online stores and other similar e-commerce websites, some may redirect to rogue sites containing infectious content. Thus, clicking advertisements displayed by Istreamer can lead to further computer infections.

All this is achieved using a virtual layer, which enables placement of any graphical content on visited sites. In addition, this application continually monitors and tracks various Internet browsing-related information including IP addresses, search queries entered into search engines, websites visited, pages viewed, etc.

Some of this collected information might contain personally identifiable details and is later shared with third parties who can misuse it to generate revenue. Therefore, the presence of Istreamer adware on your system could lead to privacy issues. If you are concerned with your privacy and Internet browsing safety, uninstall Istreamer adware immediately.

This adware is virtually identical to the Kikblaster, FlashBeat, PrintOnKey, and LolliScan applications. All (including Istreamer) claim to enhance the Internet browsing experience in an attempt to trick users to install. Once installed, they merely display advertisements and track personally identifiable data.

The purpose of Istreamer, and other adware-type apps, is to generate revenue for the developers - they provide no real value for users.

How did Istreamer install on my computer?

Istreamer is distributed using a deceptive software marketing method called 'bundling' - stealth installation of third party applications with regular software/apps. This method is essentially a scam, since bundled applications are concealed within the 'Custom' or 'Advanced' settings - these are often skipped by many users.

By not paying due attention during the download and installation processes, users skip most/all of the steps and inadvertently install rogue applicaitons, thereby exposing their systems to risk of infection. The developers of these apps are concerned only with the amount of revenue generated, and thus, do not properly disclose these rogue installations.

How to avoid installation of potentially unwanted applications?

Installation of deceptive apps such as Istreamer can be prevented by taking a two main steps. Firstly, never rush the download or installation procedures - closely analyze each step and ensure that only your chosen software is downloaded/installed.

Secondly, select the 'Custom' or 'Advanced' options - this will reveal any concealed rogue applications listed for installation and enable you to opt-out.
