Caller: Scammer pretending to be Telstra

Hacker trying to access my computer as there is a apparently a Virus and Malware crashing my system. Wanted my CSLID which is a generic code on all computers, Scammer trying to bullsh*t his way to hack and steal my bank credentials. Also this scammer has told me to call 3901 60577 just don't add the 0 at the front of the number it is for Telstra billing, the person who will answer this call just give them the Telstra ID number and your name. Hold up he didn't give me his Telstra ID. HANG UP STRAIGHT AWAY. There is so much evidence here to say this is a scam as well as I am not with Telstra. Also this scammer is using spoof numbers, (Using a web service to make calls or copying someone's legit number). Also using 0411 576 400
