QuilMiner Trojan is the latest example of this type. Keep reading ahead to know everything about this high-risk infection, what it is, how you get it, and what to do to deal with it.

What is QuilMiner Trojan?

QuilMiner is a generic name for various cryptocurrency-mining Trojan horses, developed by digital hackers and programmers to steal a victim’s resources to mine cryptocurrency. 

At first look, the name implies that these Trojan Horses mine only Bitcoin cryptocurrency, however, hackers also attempt to mine other digital currencies, such as Dash, Ethereum, Monero, etc. QuilMiner Trojan can either function as a cryptocurrency miner, or install a separate component that can do so. 

Common symptoms of QuilMiner Trojan

QuilMiner can perform the following malicious activities once it gets inside your computer system.

  • It causes high CPU usage and degrades your PC’s overall speed and performance.
  • It prevents Windows apps and programs from opening.
  • It secretly installs various toolbars and browser extensions to display weird messages and pop-ups.
  • It hampers your internet browsing experience by constantly redirecting you to irrelevant and dubious web pages.
  • It allows malware authors to gain remote access to your system and steal important personal and confidential information. 
  • It modifies the entries in the Windows registry editor and eventually slows down the system operations.
  • It disabled real-time antivirus protection and Windows firewall to stay concealed. 

How Does QuilMiner Trojan get Inside the Computer?

Below are the most commonly used tactics of distribution.

  • Malspam (spam campaigns)
  • Fake software updaters
  • Third-party freeware download sites
  • Questionable web pages that contain malicious script
  • Adult and pornographic websites
  • Peer-to-Peer file sharing and hosting networks (e.g., eMule, torrent)

How to Remove QuilMiner Trojan from Your PC

Since manual threat removal is a pretty complicated and time-consuming process, so we won’t recommend it. If you want to protect your computer from QuilMiner or any other next-gen Trojan viruses or malware, we recommend running a full system scan with a dedicated and powerful third-party anti-malware software. Choose a safe and reliable anti-malware program for your system. And make sure that you’re downloading it from its official website.
