For the first time ever, my un/pw for my personal email was compromised and someone sent hundreds of SPAM messages from my account even though my provider, Earthlink, shut it down in less than 4 minutes.
I have a new pw (my account is working properly now), I ran a full virus and spyware scan on my pc (which found nothing).
1. what else should I do to reduce the chance of it happening again and make sure there isn't something more on my pc or WiFi device?
2. Out of curiousity, what can I do to find out how it happened? I'm not a real technologist. In layman's terms, I suspect someone/something had a "sniffer" on either my home WiFi, or my Blackberry connection of via my ISP to learn the pw. What else could have happened?
I'm more concerned about other un/pw's for accounts to other services (Quickbooks, etc).
All dialog is welcome.
