Mars Stealer

Mars Stealer is a Trojan virus that can silently attack any computer with almost no symptoms and then take over critical system processes. Mars Stealer can disguise its own processes as system-related ones, thus avoiding detection during the time it is completing its malicious tasks.

It is not always possible to easily detect and remove a Trojan Horse infection such as Mars Stealer because the cybercriminals behind such malware take all possible measures to hide their malicious program and its harmful actions inside the infected system. Usually, it is very tricky to isolate the potential symptoms of a computer compromised with a Trojan Horse since most of the possible symptoms can be attributed to other hardware or software issues. However, there are several red flags that may suggest that your computer has been secretly invaded by a threat like Mars Stealer:

• You may start to receive strange error messages when trying to load some programs on your computer which messages say that certain system files are missing or damaged.
• Some of the applications that you have on your system may star to freeze for a while or stop to respond.
• You may notice that your access to popular security sites (antivirus sites, etc.) has been blocked.
• You may get numerous pop-ups on your screen or some strange messages that notify you about different unknown activities.
• Strange, unknown toolbars or some new applications and add-ons may appear at the top of the browser or on your desktop.
• Your computer may become slower than usual.
• Your system may temporarily or permanently freeze.
• The computer may restart on its own or shut down without a warning.
• You may notice that you cannot access the control panel, the task manager, the registry editor or the command prompt panel.
• Your antivirus program may fail to run a scan.

If you have noticed any of the above described symptoms, it is highly recommended that you follow the next guide to check your computer and remove the potential infection that might have entered your system. Keep in mind, though, that even if you are not facing any visible issues, a Trojan like Mars Stealer or CryptoStealBTC may still be hiding in the system and that’s why it is a good idea to run a full scan with a reliable malware removal tool.

Some types of Trojans may not allow you to launch a security program or block all attempts to run a system scan in order to prevent their detection and removal. If this is your case  and Mars Stealer is blocking your attempts to scan your system with your current antivirus software, we suggest you use the manual instructions in the removal guide above and then try to run a scan with the professional removal tool presented in the guide. It is very important to carefully remove the malicious code as soon as you notice it’s presence because this will prevent the Trojan from performing its criminal deeds. And trust us, such a malware program can harm the entire computer in a really bad way.

The Mars Stealer Malware

For instance, the criminals may use a threat like the Mars Stealer malware for harmful activities like theft of sensitive information and credentials, passwords, banking details, etc., as well as espionage, corruption of system files, deletion of certain data and even remote access to the attacked computer. Sometimes, the Mars Stealer malware may serve as a backdoor to other viruses and threats like Ransomware and Rootkits. Therefore, the sooner you take actions to eliminate it, the better.

• Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.

Hold the Start Key and R –  copy + paste the following and click OK:

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
