Stream Core

Apps like Stream Core Virus are normally not intended to cause harm to your operating system and your data. What they are created for is generation of profits from clicks on the adverts they display.

Stream Core Virus

If you’ve landed on this page, you are most probably frustrated and annoyed by the never-ending stream of aggressive sponsored commercials that have been spamming your web browser lately. Before you assume that this must be a symptom of some nasty virus infection, however, let us tell you more about the possible source of these ads. In most of the cases, this could be a browser hijacker, especially if you constantly see different pop-ups, ads, banners and page redirect links, which appear on every webpage that you visit, even on sites that aren’t typically sponsored by ads, and if your browser has had some unauthorized homepage added to it or if its search engine has been modified/replaced without your permission. This type of software is not related to Ransomware, Trojans or any malware category, but it could be quite irritating to have it in your Chrome or Firefox (or another) browser and could frequently cause random page-redirects and exposure to various third-party commercials. For this reason, the browser hijacker is generally considered as potentially unwanted.

The Stream Core Virus

Like most of its representatives, Stream Core Virus typically targets popular browsers such as Chrome, Firefox and Explorer and automatically integrates its ad-generating and page-redirecting components with them. Dealing with the constant ads streaming generated by Stream Core Virus could be quite unpleasant, especially if you spend a lot of time browsing the web and get frequently interrupted or redirected to pages that you never had the intention of visiting.

In the next lines, we will do our best to help you remove this irritating piece of software and uninstall all the changes that it has imposed on your browsing program so that you no longer need to deal with the constant irritation that Stream Core Virus may create.

The infamous “Pay-per-click” model is a common online advertising technique, which is often incorporated within such hijacker components and which dictates their behavior. This method is not illegal and has nothing to do with the criminal actions that threats such as Spyware, Trojans or Ransomware may initiate. That being said, we still advise you to keep away from the sponsored commercials that may pop-up on your screen thanks to such aggressive advertising methods because sometimes, fake or misleading ads and links may also be advertised in this way. Unfortunately, there is no way to check which messages are safe and which offers and banners could be potentially dangerous. That’s why the general rule is to avoid interaction with anything unfamiliar, sketchy, aggressive or intrusive and to uninstall and remove any component, add-on or software, which is messing with your control over the content that gets shown on your screen. This includes the content generated by apps like Stream Core Virus Virus and similar browser hijackers as well as the random on-site messages that may prompt you to click on something during your regular web browsing. It simply isn’t worth the risk of landing on something malicious or of getting your computer infected with some malicious virus program.

    After you open their folder, end the processes that are infected, then delete their folders. 

    Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


    Hold together the Start Key and R. Type appwiz.cpl –> OK.


    You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

    Type msconfig in the search field and hit enter. A window will pop-up:


    Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

    1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
    2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
    3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.

    • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

    Right click on the browser’s shortcut —> Properties.

    NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge).


    Properties —–> Shortcut. In Target, remove everything after .exe.
