My Xbox was not connecting to my profile Wednesday, so I looked up the support number online. I ended up calling a psuedo-support site. The following is what I recall from that experience.
They said my account was blocked due to suspected hacking activity. They asked me if my Xbox was on the same network as my computer. They had me download a file from teamviewer.com and I granted remote control. He paused about 15-20 seconds, and then very fast ran through some steps to show me I was hacked. What I recall is he showed me some type of dos log indicating about four lines of time-outs or disconnects or something. He said that means I'd been hacked. He opened the event viewer and showed me a green and red line graph. Then he did some more on the event viewer. Then he opened paypal and said I had to pay $199 to clean 41,000 malware files. I declined and exited the remote control session. Total time about 2 minutes.
I ran McAffee full scan with no reported files. I experienced some slow video and internet surfing the next night, and had a suspicious error at start up saying that explorer hadn't closed properly to permit shutdown. I'm pretty sure I had shut it all the way down and turned off WLAN on last use. No other symptoms.
Worried about passive tracking malware.
Please help a fool.
