How do I fix this? If I have downloaded malware etc?

I recently had my ebay account hacked items were purchased and then these silent calls started, my advice is change your passwords on everything, they have gained your personal information and they are testing the water. That's why they phone, also turn your router on and off incase they are using a remote desktop, you may have downloaded spyware or malware.
