Take a look at Netsafe NZ for current scam / malicious issues https://www.netsafe.org.nz
Don’t click every internet link you receive in emails.
Don’t accept prompts to install software from strangers, Microsoft and other computer-related companies are not going to spontaneously call you directly to fix your computer.
Do your fact-finding first. If there is no telephone number or physical address associated with any service, stop or at least compare notes with a friend before going further.
Nothing is free so if it is too good to be true then consider what is in it for the other party? (Normally your private information and more!)
