I recommend if computer and smart phone users are concerned with cyber security and scams that they seek help from the many computer clubs that operate in Australia. If you are over 50 and live in the Greater Brisbane area which covers Moreton, Redlands and Brisbane, they consider joining Brisbane Seniors Online.
A volunteer empathetic patient tutor around the same age will visit your home and give you as a guide about 12 hours of home lessons on your device and at a pace that suits. Windows, Android, Apple devices and smart phones as well as digital photography are taught. A small Linux group also operates in BSOL.
An affordable fee of $20 joining (one-off) and $45 a year applies. Learners as well as volunteer mentors are welcome to join. Applications can be done online through the website.
