I logged into Steam to see that a Russian IP had attempted to access my account. I immediately ran MalwareBytes Pro and found nothing. I changed my Steam password and the password to it's linked email.
When I accessed Steam again, I noticed my saved payment method was missing. Maybe it's removed automatically when you say it wasn't you trying to access the account? but if not...
I don't think that could have been removed it unless they also had access to my email to get the location activation code.
So, basically, I am afraid to enter my CC information on my PC again.
MWB finds nothing but I am not sure...
Any thoughts? Suggestions on another program to scan with? Should I just DBan the HDD and catch it on fire?
Most of the time if you're being hacked, is that they hacked a poorly protected forum and just ran all the login and passwords they could fetch. Now if your steam login isn't used anywhere else... use kaspersky rescue disk and let it scan. It should run off an usb stick so most malware doesn't even know it's being scanned.
I'd advise to contact steam support and ask for any purchases that you haven't made. I'd also call your bank to block your card access out of safety.
If your Steam login has the same password as your email, then you are in trouble. Make sure there are no unauthorized transactions going on on your credit cards. Usually secure servers like Steam get "hacked" by hacking into an insecure forum, stealing the info there, and then trying to login with the forum login onto more popular sites like Steam and Battle.net
Then again, it is easy to download a keylogger. Changing your passwords every 1-2 months or reformatting your hard drive can help, if you think it is worth the effort. But seriously, I had an account hacked a while ago, changed my passwords on all websites, and never had problems again.
