The reason is, you are not dealing with a normal virus but with an advanced Trojan Horse infection which can cause serious harm to your system if not removed on time. The sooner you take actions to eliminate it, the better your chances of preventing the malicious consequences of its attack from taking place. If left undisturbed, AltstApp will not spare your computer and may corrupt its files, mess with the software that is inside of it or worse – provide its creators with unauthorized access so that they can harass you any way they want. And, trust us, there are many ways a hacker with criminal intentions and with a Trojan Horse such as AltstApp or Altruistic at his disposal to mess with your virtual privacy and security. He can format the hard-drives of the PC and delete important data, steal your passwords or banking details, spy on you or secretly insert other viruses inside the compromised machine. An active threat like AltstApp may even land you a Ransomware or a Rootkit without you having a clue about it because this threat may even serve as a backdoor for more malicious programs.
That’s why, instead of passively waiting for the Trojan to reveal its full potential, we suggest you take a close look at the suggested removal methods that we have published below. There, you will find a trusted removal tool and a manual removal guide, both of which are dedicated to helping you correctly and safely detect and remove AltstApp from your system. Our advice is to carefully go through both of the options and use them in a combination to ensure that you have successfully eliminated the danger and no hidden infected files have remained on your computer.
There may be no contamination symptoms!
Trojans are famous for their disguise abilities. They may, at times, be nearly impossible to detect without the help of a reliable antivirus program because they usually use various disguise methods in order to trick the victims about their real nature and intentions. In most of the cases, such threats may appear in the form of intriguing emails with attachments, ads, discount links and offers, free downloads and updates, as well as torrents, spam or misleading web pages. In order to infect the computer, they usually need some form of interaction from the users’ side and that’s why their carriers may often ask you to click on something, to download some files or installers or to visit certain compromised pages. Once you get tricked to do that, the contamination normally takes place automatically. Unfortunately, you cannot expect to see any suspicious indications or unusual activities neither during the infection nor after it, when the Trojan starts to operate. That’s why it is essential that you have a good antivirus program which can notify you about the danger on time, before the malware has managed to complete its criminal deeds in the background of your system.

Uninstall the AltstApp 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 AltstApp. 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 AltstApp, 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 AltstApp.
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 AltstApp changes made to different system settings
It’s possible that AltstApp 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
