My provider has told...

My provider has told me that there are brute force attacks coming from my network. I have used more than a whole months worth of bandwidth in 2 weeks

Technician's Assistant: Can you describe your network setup (devices and cables used)?

Netgear orbi, apple laptops (wifi), qnap nas (wired), directv (wired)

Technician's Assistant: What happened right before this popped up?

I have been getting messages from comcast that i had a bot on my system on my iPhone according to them it has been going on since around july 4th

Technician's Assistant: What troubleshooting have you tried?

I scanned all of my computers and removed some trojan and malware files that avast security discovered and I deleted malware that my QNAP antivirus scan found. I check my orbit logs and it shows DOS Attacks in log against port 22 and port 80 every 15 seconds or so

Technician's Assistant: Anything else you want the network expert to know before I connect you?

Not that I can think of

Once installed I need the ID and Password ***** displays, i do not need the one you created, I am looking for the one that TeamViewer gives you when you open the program.

Thanks
