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


Adfly is an app of the malware category known as browser hijackers. Adfly installs in the browser and tampers with its settings without permission, which could open your system to more serious threats.


Adfly is a legitimate advertising platform, although can be easily exploited by viruses

Adfly is a legitimate file-shortening app that monetizes the shortened links. However, due to its involvement with online ads and due to some of its distribution techniques, Adfly is oftentimes referred to as a virus or adware and people usually want to remove it. Here, we will explain to you if and how this app can be problematic and we will tell you how you can get it off your computer in case it is bothering you. If you currently have Adfly in your computer and it is being annoying, you can directly go to our guide that you will find further down and use the instructions there to remove the app. However, it is advisable that you find the time to read the rest of this article because the information here will help you better understand this sort of applications and avoid them in the future. is a PUA (Potentially Unwanted Application) and we, as well as most other software security researchers, believe that is exactly that. As was mentioned earlier, this is a legitimate app that provides its customers with link-shortening functionality.

It also offers the users to get paid for each click on the links that they have shortened using its services. On paper, all of this sounds quite nice – you basically earn money for using this link-shortening service. However, there are some aspects related to this app that may not be as nice. For example, some users report that this app has gotten added to their browser without their informed permission. This most often happens when people install file bundles without taking the time to customize the setup options. If a given file bundle has this, or another PUA integrated with it and the user doesn’t uncheck the unwanted app, the latter would certainly get installed in the computer.

Another issue people may have with Adfly is that this PUA may generate ads in the browser and/or cause redirects to third-party sites. Most users get annoyed by that since the random ads, pop-ups, and page-redirects tend to make navigating through the Internet rather difficult. Oftentimes the ads are superimposed over the main part of the page, covering it and thus forcing the user to click on the advert in order to make it disappear.
Probably the biggest issue with potentially unwanted apps like Adfly is that their advertising and page-redirecting activities may open your computer to harmful malware. The PUA itself isn’t harmful – it is a legal piece of software and it won’t harm your system in any way. However, online criminals oftentimes find ways to “steal” legitimate ads and turn them into malware-distribution tools. Such ads are call malvertisements and are one of the most common techniques for spreading Ransomware, Trojans, and other similar threats. If you are ready to take the risk of getting exposed to Ransomware, Spyware, or Trojans, you can keep Adfly and benefit from its services, but we must still warn you about the potential risks of getting random ads shown on your screen.

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.

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
