Blotcreepy Virus


Blotcreepy is a browser-infiltrating malware aimed at aggressively promoting different sites by forcefully redirecting your browser to them. Blotcreepy can make changes to the infected browser, such as replacing its homepage and search engine, in order to further boost the effectiveness of its site-advertising campaign.


The Blotcreepy virus is specialized in aggressively promoting certain sponsored homepage domains, search engines, toolbars, and pay-per-click ads

This type of software is not the most harmful type of software that you may encounter, but it is not the most pleasant one either. Most users who have Blotcreepy and CaptchaModern in their system complain about the aggressive page redirects, ads, pop-ups, and banners that the application may generate on their screen during web surfing. If you have also been experiencing the same disturbance and Blotcreepy is the cause of it, on this page we will show you how to detect and manually remove the unwanted browser hijacker and uninstall its ad-generating and page-redirecting components once and for all.

Before you go straight to the instructions in the removal guide below, however, let us first describe the common behavior of browser hijackers in general and the ways you can prevent them from sneaking into your system without your knowledge.

Browser hijackers and their most common behavior

Browser hijackers are special pieces of software used by online advertisers and programmers to promote and display huge amounts of sponsored ads, banners, pop-up links and promotional pages on users’ screens during their regular web surfing. Usually, such pieces of software resemble normal browser add-ons and may get incorporated into popular browsers like Chrome, Firefox, Safari, Edge, and others.

Blotcreepy is a new representative of this advertising software, and as such, it is specialized in aggressively promoting certain sponsored homepage domains, search engines, toolbars, and pay-per-click ads by imposing them on the users’ screens. In its nature, such an application is very different from typical viruses or other malicious threats like ransomware, spyware or Trojans. However, despite the fact that its advertising activity is not against the law, many users consider it annoying and potentially unwanted.

Despite its questionable behavior, know that Blotcreepy isn’t actually some kind of sneaky application that installs itself without your permission and starts to spam your screen with pay-per-click commercials. Such a stealthiness is typical for the real viruses, especially for Trojan and ransomware infections, which can infiltrate your computer without any symptoms. A browser hijacker like this, however, is typically installed by the users themselves, usually when they perform a careless software installation.

A common mistake most people make when they launch the setup of a new application, a torrent, a free installation package or an update is to run through the steps without carefully reading the EULA and without having a look at the Advanced/ Custom settings. What they typically don’t pay attention to is that Blotcreepy and similar advertising applications are commonly bundled inside different automatic installers and if not removed manually from the installation manager, they may become part of the system when the setup process completes. That’s why, if you want to stay away from browser hijackers and other potentially unwanted applications, we advise you to carefully read all the installation settings and be selective about your software sources. This way you may save yourself from the need to uninstall different annoying applications later.

    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.
