    If you would like your computer thoroughly checked, then please provide Farbar Recovery Scan Tool (FRST) logs for analysis.

    https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

    Note: If you are using Edge or Chrome, SmartScreen may initially block the download. Click on the three dots next to the warning and select Keep => Click the Delete drop arrow => Keep anyway.

    • If your computer's language is not English, rename FRST64.exe to FRST64English.exe
    • Run the tool, leave the default settings, and press Scan.
    • Zip the logs, FRST.txt and Addition.txt, then upload to a cloud storage service like OneDrive, Google Drive or gofile.io
    • Post the share link.

    To address the Trojan:Win64/RadThief.ARR!MTB detected on your PC, follow these steps:

    1. Run a Full Scan with Microsoft Defender: Make sure to perform a full system scan to identify and remove any malicious software. If you haven't already, you can access this by going to Settings > Update & Security > Windows Security > Virus & threat protection, then select Scan options and choose Full scan.
    2. Use Microsoft Safety Scanner: Download and run the Microsoft Safety Scanner, which is specifically designed to find and remove malware from your system. Keep in mind that this tool is only effective for a limited time after downloading, so ensure you run it shortly after downloading it. You can find it here.
    3. Remove Suspicious Software: If you notice any unfamiliar applications installed on your computer, go to Settings > Apps > Apps & features and uninstall any suspicious software.
    4. Check Browser Extensions: Review your browser extensions and remove any that look unfamiliar or that you did not install. This can help eliminate unwanted behavior in your web browser.
    5. Change Your Passwords: Since Trojans can capture sensitive information, consider changing your passwords for important accounts, especially if you notice any unusual activity.
    6. Enable Real-Time Protection: Ensure that Microsoft Defender Antivirus is enabled for real-time protection to help prevent future infections.
    7. Be Cautious with Downloads: In the future, avoid downloading software from untrusted sources, especially from illegal movie websites, as they can often host malware.

    If the problem persists after taking these steps, you may want to consult a professional for further assistance.
