So the past few days I've gotten over 30 e-mails from Steam Support telling me that somebody is trying to access my account. They give me an IP address and a code that I can put in to confirm that it's me. All of these connections are coming from Europe.
I've changed my password and security question several times and have scanned my computer for viruses and trojans (avast, superantispyware, malwarebytes) and have found nothing. Sometimes these messages come right after changing my password. I haven't yet tried changing my information from another computer. Could I maybe do it from a virtual machine?
How do I stop this and how can I retaliate? The IP in the pic has port 3389 open.
