Allowandgo is a potentially unwanted app (a.k.a. PUA) that is capable of transforming browsers such as Chrome, Firefox, and Edge into ad-displaying platforms. Allowandgo makes money through the display of paid adverts and the promotion of sites that pay commissions to get popularized.


The Allowandgo virus will display pop up ads and messages

If Allowandgo or another similar app like Captcha Source Center, iStart Search Bar has entered your browser and now you are forced to put up with sudden page redirects to unknown sites and generation of obstructive ads during each browsing session, then we advise you to read on in order to learn more about this type of app and to find out how you can uninstall it.

In addition to the frequent redirects and ad pop-ups, other common symptoms that may come from Allowandgo are the change of the main browser’s homepage and/or Omnibox search engine. These changes allow the browser-hijacking app to put more ads on your screen and to automatically open the sites of its sponsors without requiring your permission. Usually, once the hijacker introduces changes to the targeted browser, those changes cannot be reversed as long as the unwanted app stays attached to the browser. Therefore, the only way to bring back your browser to its normal state and remove the elements that Allowandgo has added is to uninstall this undesirable app. If you have already made an attempt to remove the hijacker, you have likely found out that it cannot be removed in the same way you’d uninstall a regular program or browser add-on.

The reason for this is mainly that the developers of hijackers like this one earn more money the longer their apps are able to stay on the users’ computers because that would increase the number of popups and banners displayed by the hijackers. The bigger the number of displayed ads and page redirects, the more clicks/visits those ads and sites would get. The hijacker ads and site redirects generate income based on how many people interact with them so it makes sense for the developers of software such as Allowandgo to make their apps as difficult to uninstall as possible. Due to the tricky uninstallation process of most hijackers, people oftentimes think that their computers have been hit by some highly infectious virus program or a dangerous malware such as Ransomware or Spyware. The browser hijackers, however, are primarily focused on making money through their ads and site promotions, which means that they are unlikely to try to cause any damage to the computers where they are installed.

Why you must still be cautious around apps like Allowandgo

It is not advisable to allow this hijacker to stay on the computer for long due to the increased chances of ending up on some unsafe page due to the unauthorized ad generation and site promotion occurring in the browser while the hijacker is still in it. Many illegal sites known for spreading Ransomware, Trojans, Worms, and other threats may be promoted by hijackers, so if you have a hijacker in your computer, it may not be safe to use your browser and to click on the ads and pop-ups that get displayed in it. Therefore, we suggest that you try the removal guide from below and uninstall the Allowandgo hijacker with the help of its instructions.

    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.
