My yahoo mail seems to have been hijacked -- there are 61 sent emails in my sent mail folder that I didn't send, all were sent at 2:08 or 2:09 pm, and I think it blasted an email out to all my contacts. The only reason I noticed it is because I got a bunch or responses (mailer daemon failures, out of office, plus a handful of my contacts asking whether I'd actually sent this out).
My question: how do I figure out whether one of the PCs in our home that I use to access this email account is infected, whether somebody else's PC is infected, or whether Yahoo's servers were compromised somehow?
This PC seems to be acting OK -- it's Vista Home Premium with Windows Defender and Symantec Anti Virus (version 10 something) running. I read something online about using Hijack This and posting the log file somewhere, but am not sure whether that's the best next step.
