Sfone is a Trojan horse virus that can cause very serious harm on your PC. Like any Trojan, Sfone can be employed by its developers for a wide range of malicious purposes. In this brief article, we will aim to give users an idea of what they can roughly expect from a variant such as Sfone. But since you have already discovered this Trojan in your system, some congratulations are already in order. Trojans are notoriously stealthy and sneaky and detecting them is normally no easy feat. Cases where viruses of this type were able to remain hidden for up to several years are not at all uncommon. And this is one of the reasons why cyber criminals love this type of malware so much.
The Sfone malware
The Sfone malware is quite versatile. There are numerous different types of tasks that the Sfone malware can be programmed to perform whilst on the victim’s computer, and this is likely why Trojan horses are easily the most numerable category of malware on the internet. But now that you’ve detected the culprit, it’s important that you have it removed as soon as possible. And below we have put together a removal guide containing detailed instructions on how to do this.As any Trojan, Sfone may have been programmed to steal valuable information from you, and using a variety of means too. For instance, you may be spied on through your keystrokes, which the malware can use to learn your passwords and other sensitive data. Furthermore, software of this type has also been known for its ability to reroute your whole traffic to the servers of cybercriminals. And that way anything you do online becomes visible and known to them.
The possible effects of Sfone
Other options include using your computer for its resources in order to, say, distribute spam. Alternatively, your PC could be put to work to mine cryptocurrencies and send them to the hackers behind Sfone or Pinaview. Trojans also often act as backdoor viruses, meaning they have the role of bringing in other malware into the computer. Most commonly they are used in such combinations with ransomware, but not only. This should serve as a good reason to scan your system very thoroughly with professional antimalware software as soon as you have removed Sfone from your computer.
With that in mind, be sure to pay attention to your browsing habits from now on to minimize the risk of landing an infection like this again. Trojans are typically distributed using spam and phishing schemes, as well as through infected or fake online advertisements. Usually you are more likely to come across these when you visit different sketchy and unsecure web locations. Try to steer clear of those, and perhaps consider investing in a reliable antivirus program to keep all external threats at bay. Last but not least, keep in mind that installing system updates whenever those become available is also a crucial part of maintaining your system’s safety.
To try and remove Sfone quickly you can try this:
- Go to your browser’s settings and select More Tools (or Add-ons, depending on your browser).
- Then click on the Extensions tab.
- Look for the Sfone extension (as well as any other unfamiliar ones).
- Remove Sfone by clicking on the Trash Bin icon next to its name.

Uninstall the Sfone app and kill its processes
The first thing you must try to do is look for any sketchy installs on your computer and uninstall anything you think may come from Sfone. After that, you’ll also need to get rid of any processes that may be related to the unwanted app by searching for them in the Task Manager.
Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware. Also, if you aren’t allowed to go through with the uninstallation, proceed with the guide, and try again after you’ve completed everything else.
- Uninstalling the rogue app
- Killing any rogue processes
Type Apps & Features in the Start Menu, open the first result, sort the list of apps by date, and look for suspicious recently installed entries.
Click on anything you think could be linked to Sfone, then select uninstall, and follow the prompts to delete the app.
Press Ctrl + Shift + Esc, click More Details (if it’s not already clicked), and look for suspicious entries that may be linked to Sfone.
If you come across a questionable process, right-click it, click Open File Location, scan the files with the free online malware scanner shown below, and then delete anything that gets flagged as a threat.
After that, if the rogue process is still visible in the Task Manager, right-click it again and select End Process.
Undo Sfone changes made to different system settings
It’s possible that Sfone has affected various parts of your system, making changes to their settings. This can enable the malware to stay on the computer or automatically reinstall itself after you’ve seemingly deleted it. Therefore, you need to check the following elements by going to the Start Menu, searching for specific system elements that may have been affected, and pressing Enter to open them and see if anything has been changed there without your approval. Then you must undo any unwanted changes made to these settings in the way shown below:
Type in Start Menu: View network connections
Right-click on your primary network, go to Properties, and do this:
Type in Start Menu: C:\Windows\System32\drivers\etc\hosts
Type in the Start Menu: Startup apps
Type in the Start Menu: Task Scheduler
Type in the Start Menu: Services
Type in the Start Menu: Registry Editor
Press Ctrl + F to open the search window
