Tech Support Scammer says my computer has worms

I called these tech support scammers on the Australian number that appears on their popup: +61 1800431462. This is a www.symbionetworks.com VoIP number and they refuse to take the number down. The scammers seem to be blocking silent numbers most of the time. The scammers audio wasn't very good.

The scammers used Rescue by LogMeIn for their Remote Access Tool.

I used VirtualBox with Windows 8.1(This is for all of my videos).
Recorded with ShareX(I use this for all my videos) and edited with Resolve(I use this or Vegas Pro for most of my videos).
