i just found out the method that my professor used to do:
1.create virtual machine on externall hdd
2. download files using that virtual machine
3. if someone is going to come over to check ur pc they won't find anything on it(no logs, cache, even mac adress will be different) but remembr to hid this hdd
4. than they will have no evidence on u or assume someone steals ur signal
5. THEY WILL NEEEEVER CATCH U!
