A potentially unwanted piece of software known as Tumgir has reportedly affected the browsers of a number of web users recently. Some common complaints related to Tumgir include a change in the default homepage, and the installation of a new toolbar, as well as a stream of unstoppable ads, pop-ups and banners.

The Tumgir malware may easily infect a wide range of browsers that are regarded to be safe

Such alternations can be disturbing and even concerning from a first glance, but, to be clear right from the start, applications like Tumgir are not as harmful as malware (Ransomware, Trojans, Spyware) or computer viruses. In many cases, however, users incorrectly believe that the browser hijacker components that are injected into their browser are viruses or other malicious software. But unlike the dangerous forms of malware mentioned above, programs like the one that altered your home page to Tumgir will not try to access or encrypt your files or damage your system. Still, such apps may easily infect a wide range of browsers that are regarded to be safe (such as Google Chrome or Mozilla Firefox) and cause them to function abnormally.

This typically leads to irritation to the majority of users who find it difficult to browse the web without being redirected to random sites or interrupted with hard-to-remove ads, pop-up notifications and banners on t heir screen. Of course, the level of tolerance when it comes to page redirection and clickbait advertisements (such pop-under ads, pop-ups, and auto-redirects) may vary – many users may find these activities extremely annoying, while others may not give a second thought to them. Nevertheless, in most cases, a program like Tumgir should better be uninstalled from the system as soon as possible. You’ll find a lot of useful information about the exact removal steps in this article and the instructions below.

The Tumgir Malware

The Tumgir malware may have a long-term effect on your system’s security, despite not being interested in encrypting your data like a Ransomware or corrupting the OS. That’s why when it comes to online safety, the Tumgir malware is a cause for concern for a multitude of reasons.

For instance, you may be redirected to a site that you don’t trust because of ads served up by Tumgir. And, as you may know, your chances of becoming infected by malware increase dramatically if you land on an untrustworthy website with questionable content. The same is valid for clicking on random ads and on-screen notifications. Unfortunately, these are impossible to remove unless you uninstall the software that is generating them. And that’s exactly what the hijacker you’re currently dealing with is doing, so you should better remove it with the help of the removal guide below.

If you want to prevent a close encounter with programs like Tumgir and McAfee virus popup in the future, our advice is to keep an eye out for additional components in the installers of other attractive and desirable programs that you install on your computer. In many cases, browser hijackers may be added there as “free bonus” software, typically under the Advanced/Custom installation settings. Unchecking them from that menu during the setup process, however, will save you from the annoyance of random page redirects, different banners, pop-ups, and homepage modifications caused by such software.

    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).
