This page aims to help you remove Mobifoth. These Mobifoth removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

If all of your browser apps (Chrome, Firefox, etc.) have started broadcasting many ads or their default homepages and search engines have been substituted with new ones, or in case they have begun redirecting you to unknown web locations, it is probable that your PC has been contaminated by a specific browser hijacker. The name of this software is Mobifoth and we will thoroughly discuss it below.

What does a browser hijacker represent?

Any browser hijacker represents a program, which could show the aforementioned features: it may modify the settings and the appearance of your browser apps – even the most common ones: Chrome, Explorer or Firefox might be affected. Such actions could greatly irritate you with its regular ad streams in the form of pop-ups, bright banners or variously shaped boxes. The potential redirection processes, which may result from the infection with this program, could indeed be very disturbing as the loaded pages may be unfamiliar or suspicious. Furthermore, you might not really like the new homepages and search engines this software may set on your browser apps. As a whole, the way this program could affect your PC is harmless, however, it might be awfully irritating.

Does Mobifoth represent a virus?

As a representative of the browser hijacker software category, this program doesn’t even slightly resemble any kind of malware we are aware of. For example, any usual version of Ransomware can get self-installed on your system, then access your file storage spaces and encrypt all the important data there – something completely impossible for a program like cannot. One more comparison could be made with any exemplary Trojan version. Such a virus is likely to sneak into your computer through vulnerability, and it can allow the hackers who created it to spy on you. Awful as it may sound, they could even watch you through your webcam, keep track of your private credentials and hijack your identity. None of these is a characteristic feature of any browser hijacker that exists nowadays.

However, why are the members of this software group annoying your with all the modifications they are capable of inflicting?

All the irritating changes could result in are in fact legal and can cause no actual harm to you or the affected devices. Its developers have set this piece of software to simply promote new homepages, unknown search engines, products, services, etc. The act of advertising anything is neither malicious, nor illegitimate. Still, the flow of pop-ups and banners, which may be overwhelming you while you are online, may not be what you want to experience at all. However, they are not even close to what we call cyber danger. Actually, the reason why programmers create hijackers is that using them for advertising services/products may earn them big profits.

If Mobifoth is not an actual virus, how has your system ended up infected?

Mobifoth may come from plenty of various sources. Any torrent or a shareware-distributing web page could have as a component, and as soon as you visit or download anything from such a web location, you may give Mobifoth your approval to get installed on your PC. It may also be lurking inside the so-called program bundles. Nonetheless, the act of just downloading a bundle will NOT infect you with an ad-generating piece. Installing it improperly, however, might leave you contaminated.

What does a program bundle represent? How to install it?

Any software bundle normally represents a set of free programs and games, which are put together and distributed together, usually for free. The recommended way of installing such a bundle on your PC and if you want just a particular program from it, is NOT to give your permission to the whole content of such a bundle to get incorporated. The installation feature which provides the chance to opt in and out of the bundle components and their features is the CUSTOM (also called Advanced in some wizards) one. Choose it for the completion of the installation process always!

We should also point out the installation features you can’t afford to opt for if you want to keep your system Adware- and hijacker-free. They are all the ones that will ensure an easy installation process. Most of the time they appear as ‘Recommended’, ‘Easy’, ‘Quick’ or ‘Default’. Do not ever select any of them!

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

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:

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.

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Type Regedit in the windows search field and press Enter.

Inside, press CTRL and F together and type the threat’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!


    • Did you visit the separate guide for Mac users (there’s a link to it in the guide above)?

  • I went through all of the manual steps (for Windows users) and could not find any evidence of Mobifoth on my system, as outlined in the article. And yet, it keeps popping up. Any other ideas? Thanks.

    • Did you search through the Registry Editor? Also, you can send us a screenshot of the programs that are installed on your PC (from the Control Panel) – this might help us determine what’s causing the issue.

      • I did search through the registry. Zero hits for “mobifoth.” I ended up downloading and using the paid version of SpyHunter. This has also failed to fix the problem. Although it did reveal a clue. It popped up a dialog for me to approve the activity of php.exe. I build web sites for a living and use PHP on a daily basis, so I clicked “allow.” Upon doing so, a new pop-up opened immediately. Since disabling php.exe, I am no longer seeing pop-ups, but of course I am unable to use PHP for my work.

        • Since you’ve got the paid version of the program, you have the option to request live support from its developers where you will be provided with a customized fix for your issue.
