I have an e-mail address ending "Rocketmail.com" which is hosted by Yahoo...
Last night, I apparently e-mailed everybody in my address list (And a few that weren't) just after midnight.... whilst I was safely tucked up in bed...
One or two of these were "Bounced" back to me as they contained spam...
the E-mail that I apparently sent (Whilst both I and the 'puter were asleep) appeared to come from me, and contained a link to ???

I ran AVG anti virus (Free version) this morning...nothing...
To be sure, I also ran Malware anti thingy (Mbam) again the free version...nothing..
Can anyone enlighten me as to whether this is a problem my end or with the Yahoo mail service? and how to prevent a recurrence??
TIA...
