I am spending the night at my grandparents' house. I left my Steam account logged in from a few weeks ago. I found out today they got a backdoor trojan from "Spider Solitare". I am a little concerned that my Steam account may be stolen. I first noticed a bunch of ads through the desktop, then I scanned the SpiderSolitare.exe on VirusTotal, and SuperAntiSpyware identified it as a backdoor trojan. I did not open Steam, but my account information was still saved. I would like to change my password, but I can't until I get home. I also left my e-mail account logged in. I had some OCD problems when I set up my accounts, so I don't know my security questions and answers. My questions are, even though I didn't open Steam, will they still be able to steal my account? Same goes for e-mail. The computer is off and unplugged right now, but they are going to call Geek Squad tomorrow morning. Will even turning on the computer give the hackers my account information?
Thanks in advance for any input.
