Also you can have a keylogger... You can get them easily for downloading "Steam Hacks" or "CS:S Hacks"...
I was at youtube and I saw one guy doing this steam password like finder... It was a keylogger... I just simply detected his Ip and messed up his router... Never download things from unknown creators...
Also download Malware Bytes... Blocks your connection to Potencial Malecious websites and warns you about any possible virus... It also leaves a log so experts can analyse it.
I can crack that for you if you want...

If you wanna be safe, go with Nod32 and stay away from strange downloads. Also, have you logged into some Steam Community websites? Like, a guy sent you a link to login? That could also be your problem.
And yes, download Malwarebytes. It's a very good and effective program.
