Malicious Malware

I've been informed that my laptop has a malicious malware from the IT department in my school, the malware "Scans the entire network for phones and vulnerablilites on the phones." is there any way I can find and delete it? I've downloaded Avast Security to try to find it but no luck.

When you have already been infected with the malware, the best solution is to wipe the machine clean, reinstall macOS and restore your own documents and data from backup.

Ensure that you update macOS and your programs to the latest versions immediately after setting up the system to ensure that you do not get malware again.

If you have programs on cloud services such as Dropbox or iCloud, make sure to validate that they do not contain malware before running them on your newly installed computer.
