CoinMiner Trojan: How to Completely Remove?

Today I found my CPU being used more than usual. I checked on that and noticed one of the svchost.exe processes running continuously at around 20% CPU. As this seemed a little suspicious, I downloaded Malwarebytes and ran a scan. It found a pack of Trojan.Downloader and Trojan.MalPack files are located in subfolders of my C:\Users\Appdata\Local\Temp folder.

I put them in quarantine. Unfortunately, Malwarebytes still reports the reoccurrence and blocking of a file called C:\ProgramData\ndfbaljqaqzm\dckuybanmlgp.exe. I did some research and this seems to be a CoinMiner so I suspect I did not get rid of the whole problem. The file is continuously recreated and quarantined.Reddit User

Stopping Recurrent Malware

Identify and Delete Malicious Processes: Monitor your system’s resource usage via Task Manager to identify any suspicious processes that consume a high percentage of CPU. Right-click on the process and select ‘Open file location’. Delete the files if they are in unusual or temporary directories like Temp or ProgramData.
Disable Startup Entries: Use the System Configuration tool (msconfig) or Task Manager to disable startup items that are linked to the malicious software.
Clean Temporary Files: Clear out your Temp folder using the Disk Cleanup tool or manually delete the contents to remove any executables or payloads left by the malware.
Delete Registry Entries: Malware often creates registry entries to ensure persistence. Use the Registry Editor (regedit) with caution to locate and delete any suspicious entries. Look for entries under ‘RUN’ sections within ‘HKEY_CURRENT_USER’ and ‘HKEY_LOCAL_MACHINE’.

Prevent Future Infections

Enhance Browser Security: Install ad blockers and script blockers to prevent malicious scripts from executing while browsing.
Update Regularly: Keep your operating system, browsers, and all installed software updated to protect against vulnerabilities used by malware.
Practice Safe Browsing: Be cautious with email attachments and downloads from untrusted sources. Avoid clicking on suspicious links.

By diligently following these steps, you can effectively remove persistent malware such as Trojans and CoinMiners from your PC and take preventive measures to safeguard against future infections. For complex cases, consider consulting with a professional cybersecurity expert.
