    Frequently Asked Questions

    Q: How can I determine if a high CPU process is a miner?

    You can check its folder location. Real system processes run from C:\Windows\System32, while miners often run from Temp or AppData.

    Q: What should I do if my antivirus is blocked?

    Boot into Safe Mode with Command Prompt and use command-line utilities to re-enable services, or execute Microsoft Defender Offline scan.

    Q: Is a hosts file modification dangerous?

    Yes, modifying the hosts file allows redirecting legitimate traffic (like update servers) to malicious sites or local addresses.
