I know this is going to sound like a dumb and overly paranoid question, but here goes anyways
(forgive me in advance!):
I use Yahoo! mail as one of my email accounts. That email account is attached to my fantasy basketball league in Yahoo! Sports. However, I have not used my Yahoo! email account in close to a year now (instead, I use Gmail) after getting a virus/bug attached to a MS Word document (sent from an unscrupulous friend last year). That email of my friend's with the virus attached is STILL in my Yahoo! mail account. It's sitting in one of my folders.
I have not used that email account in almost a year and am on a different/new computer anyways.
HOWEVER, I did log into my old Yahoo! email account this week, in order to accept an invitation from an old fantasy basketball league pal to join his league this year. Note: I ONLY opened the fantasy basketball league invitation and DID NOT open or look at any other email. But, could the existence of a malware infected email (from my other friend who sent that MS Word document) sitting in my account somehow infect me now?
In other words, if I have a malware infected email sitting in my email account, but I don't open/read that email, nor download any attachments from it, could the malware somehow transfer to me still (just by virtue of logging into my email account and/or looking at other non-infected emails)?
Hope this makes sense and appreciate the feedback for a bizarre question!!
