What Is App x?
App x is a potentially unwanted program that displays trojan-like behavior. The app may be detected as TrojanPSW.Vidar and Trojan.Agent.Win32.4093738, indicating its potential to act as a password stealer or a general malware threat.
App x’s behavior is similar to that of a trojan, which means that the app can infiltrate systems stealthily, compromise user data, and facilitate unauthorized access. Users encountering this detection should treat it as a serious security risk and take immediate steps to quarantine and remove the program, with the help of an anti-malware program.

App x – Infection Methods
According to our research, cybercriminals use the most popular tactics to distribute App x. These include social engineering and phishing tricks, e.g. the forgery of services and well-known companies by impersonating them. This forgery is done by creating template-based email messages and websites. Both of them may include stolen or fake content, as well as domain names that sound similar to the real ones.
In addition, the App x trojan can be placed in what is called payload carriers, or virus files that will lead to the malware deployment once they are executed, for example from a malicious email attachment. Such can be documents across all popular office formats.
You should also know that trojanized files can be easily uploaded to file-sharing networks and popular download platforms. These are widely used by computer users to download files from the Internet. So, if you have downloaded a program from such a portal, this download may have been the intrusion gate of a trojan infection.
App x Malicious Capabilities
The trojan will run several dangerous actions, including:
- Persistence mechanisms, e.g. modifying system configurations or uses scheduled tasks to maintain persistence across reboots.
- Remote access to allow attackers to execute commands, steal sensitive data, and manipulate files on the infected machine.
- Data exfiltration capabilities to collect and transmit sensitive information such as credentials, system configurations, or usage patterns to a remote server controlled by the attacker.
- Command-and-Control (C2) communication which relies on encrypted or obfuscated protocols to communicate with its C2 server, making it harder to detect.
We recommend that every detected App x instance is removed as soon as possible to prevent further damage.

Preparation before removing App x.
Before starting the actual removal process, we recommend that you do the following preparation steps.
- Make sure you have these instructions always open and in front of your eyes.
- Do a backup of all of your files, even if they could be damaged. You should back up your data with a cloud backup solution and insure your files against any type of loss, even from the most severe threats.
- Be patient as this could take a while.
- Scan for Malware
- Fix Registries
- Remove Virus Files
Step 1: Scan for App x with SpyHunter Anti-Malware Tool
Step 2: Clean any registries, created by App x on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by App x there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.Step 3: Find virus files created by App x on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
