The Redstringline is a rogue webpage that steals the settings of your browser by installing a rogue browser hijacker in it. The Redstringline hijacker can get attached to any browser – Chrome, Firefox, Opera, etc. – and flood it with aggressive pop-up ads and page-redirects.

You shouldn’t underestimate the Redstringline virus browser hijacker

As soon as this browser hijacking-software gets added to your browser, you will know that it is there. Changes to the starting page of the browser, to its default search engine, as well as frequent page-redirects to unknown and questionable pages are all sings that there’s something undesirable added to the browser you are using at the moment. However, note that there are a lot of sketchy sites with overly-aggressive ads that cause the browser to behave in a similar way. If the ads, pop-ups, and page-redirects cease once you leave such a site, then the issue was probably with that site alone and not with your browser. However, if the obstructions persist no matter what site you are on, then you most certainly have some sort of hijacker like Redstringline in your browser that must be dealt with.

How dangerous is it?

Though unwanted software components like the Redstringline browser hijacker and Home Search Design are commonly referred to as viruses, they aren’t actually very dangerous by themselves. For the most part, they are more of an irritating obstruction rather than an actual threat to the user’s online security and privacy. That said, you shouldn’t underestimate a browser hijacker because, even though it’s probably not capable of directly harming your system, there’s always a chance that the content it spams you with may be unsafe. For example, many online scammers use browser hijackers to lure potential victims to their phishing or malware-distributing sites, where the user may have their personal data stolen or from where they may unknowingly download a malicious program such as a Trojan or a Ransomware onto their computer.

All in all, even if Redstringline is not as dangerous as some users may fear, it could easily end up being a gateway for significantly more problematic threats, which is the reason its removal is highly advisable.

How to deal with Redstringline

 Dealing with browser hijackers isn’t overly complicated, and you should be able to delete this one from your computer with the help of the guide shown below and/or with the help of the professional anti-malware tool posted on this page. However, it’s not enough to simply delete this rogue app – you must also make sure to keep other such unwanted programs away from your PC in the future. To prevent other hijackers from getting installed in your system and browsers, you need to avoid visiting sketchy sites and downloading questionable free software. Also, if you get a suspicious pop-up in your browser when you try to visit a certain website, do not interact with it and instead simply close that browser tab/window. A lot of hijacker sites take over the user’s browser via disguised site-permission pop-ups that users often click on without stopping to think what about what they are actually interacting with. Last but not least, if you are installing a new program on your PC, check the Advanced/Custom settings in the installation manager and uncheck any optional bonus/additional components that you don’t need to get installed on your computer. Oftentimes, such optional installs are browser hijackers, adware, or another form of potentially unwanted programs, so they are usually best left out of the installation process.

    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.
