1. First close the intrusion tool. The mt manager prompts that an intrusion tool has been detected and the tool needs to be closed immediately to avoid further harm to system security.

2. Secondly, scan for viruses and use anti-virus software to fully scan the system to kill all possible viruses, Trojans and other malware.

3. Finally, clean up the system and clean up junk files, temporary files, useless registry entries, etc. in the system to ensure that the system runs clean and fast. This completes the situation where the mt manager detects the intrusion tool.
