CStealer, the Trojan we will tell you more about in this post, is a new addition to the notorious Trojan Horse malware group and, on this page, there is a thorough removal guide with step-by-step guidance on how to remove it. Keep in mind, however, that CStealer is an advanced threat that can hide deep in the system. That’s why, to avoid deleting the wrong files, you need to execute the steps exactly as described.

What are the Trojans capable of?

The Trojans are probably the most famous class of malware. For most web users, however, what they do is still a mystery. The reason is, threats like CStealer are incredibly versatile when it comes to the malicious actions they can perform. When they infect the system, the Trojans initially appear to be something completely harmless. Once installed, they can be controlled remotely by the hackers who give them instructions on what to do. That’s why we can’t tell you precisely what kind of damage you should expect. But we can surely list some of the most common uses of these infections, so you can get an idea of their versatile nature.

One of the most common uses is for theft. Trojans can be used to steal sensitive information such as personal or work-related documents, account login credentials, passwords, financial information, credit and debit card numbers, etc. The obtained information can be transferred to remote servers controlled by hackers and it can be used to perform crimes such as blackmailing, online banking fraud, theft of identity, and more.

A Trojan like CStealer can also be used to exploit the resources of your machine. For example, this malware can employ the computer’s RAM and CPU to mine cryptocurrencies for someone else. Or it could turn the machine into a bot and use it to send out spam and spread malware such as Worms, Spyware, and Ransomware to other computers. And if this is not dreadful enough, a Trojan can hack into your camera and/or microphone and monitor your conversations, capture embarrassing videos and audio files, and even record everything you type on your keyboard.

The above is just a very small portion of the potential harm that an infection such as CStealer may cause. Therefore, it’s best not to wait any longer and remove this Trojan as soon as possible. It would also be a good idea to learn how to avoid those threats in the future as they can compromise you again if you happen to click on one of their numerous transmitters. That’s why the best way to protect your computer is to invest in a better antivirus program and to keep it up-to-date with all the new virus definitions. We also advise you to browse the web safely and avoid potential sources of malware such as illegal download sites, spam emails, online ads, and shady attachments.
