I moved back to college about a week ago and some strange things have been going on since coming back. I wasn't able to connect to the internet reliably. A lot of the times I would get a message saying my connection had timed out. In addition, McAfee would often pop up with the message saying a risky connection had been blocked. The IP address for the block was 188.229.89.121 and next to Last Attempted By: it says Host Process for Windows Services.
So naturally, I did some research on where this IP address originated from. I found this article about it: http://research.zscaler.com/2011/08/dns-changes-from-w32rorpian.html . If you scroll down to the 'Original Post' section, those symptoms and events described are exactly what happened to me. I then plugged in my girlfriend's MAC notebook into the same ethernet port in my dorm room and the same events happened. The screen telling you to update your browser popped up, etc. This leads me to believe that my computer isn't infected with anything, especially since I have run many full, clean scans with McAfee.
I called my campus's tech department and told them about what was happening. I also told them about the risky connection and gave them the IP address that was blocked. Hopefully they will block this IP from coming through. I'm still paranoid about why this happened to me. Was it something I did or was it the campus network's fault for letting it through? Is there anything I can do to make sure my computer is clean? Thanks
