This is far too complicated for a person who uses computers recreationally.
its not really acceptable to send us a link to an explanation where you need a degree in computer science to a) understand it b) actually implement the changes they're suggesting.
I actually went through all of the steps and now 1) HM2 still is getting quarantined and 2) I have changed the security settings on various different files / programmes and not sure if it is safe anymore.
nowhere when I was paying for HM2 did it mention that there may be constant security issues that you may need to adjust various program and file settings.
I suggest you send us all step by step instructions on how to get HM2 working correctly without issue or I will be requesting a refund.
