Luca Stealer Malware
The Luca Stealer malware can give access to your PC to the hackers, who can establish remote control and heavily damage your entire machine.

For instance, Luca Stealer may alter the settings of your OS without your knowledge, steal your personal or financial information, create system vulnerabilities or download more threats onto the computer which may include ransomware, spyware or rootkits. Like most Trojan viruses, this one can give access to your PC to the hackers, who can establish remote control and heavily damage your entire machine.

Unfortunately, in some of the cases, it may not be enough to use your security program to remove the malware because Luca Stealer may oftentimes disable the anti-virus program and the firewall in order to prevent you from detecting and removing its malicious code. It may also stop you from using the Internet or installing any other program on your system.

Below you will find a manual removal guide and a professional removal tool, both of which are good options for removing Luca Stealer.

The harmful effects of Luca Stealer

Created with the purpose of causing harm, Luca Stealer is a tool that can be used for many different types of cybercrime. Unfortunately, it is very difficult to say what exactly a Trojan horse of this type will do inside your machine because the hackers who control it can program it to perform various criminal tasks.

Another nasty aspect of this infection is its stealthiness. Luca Stealer, like Altruistics, rarely shows any particular symptoms that would indicate its presence and gain users’ attention. This makes the task of detecting and removing the malware even more challenging provided that you may not even know that you have been infected before any serious damage occurs in the system.

The Trojan may oftentimes mimic some important system files and processes, which, without the help of a reliable antivirus program, may not be detected by users as malicious. And this is where the presence of a trusted security tool plays a very important role. Such software can not only provide protection and prevent an infection but may also notify you about any hidden malicious processes, which the Trojan may be carrying out in the background.

    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. If you see a screen like this when you click Uninstall, choose NO:



    Type msconfig in the search field and hit enter. A window will pop-up:


    Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.

    notepad %windir%/system32/Drivers/etc/hosts

    Type Regedit in the windows search field and press Enter.

    Once inside, press CTRL and F together and type the virus’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!
