AIM account from years ago hacked, now what?

[JimKiler]

A friend tipped me off to emails from my old AOL Instant Messenger, AIM, account sending out emails to her. I had not signed into AIM half a decade and did not realize email was added to my account. I got in with my password and saw the emails. AOL said to do a virus scan on my PC which I have done recently but should do a full one again. I use MS Security Essentials v2 and also Malware Byte's Anti-walware. I also updated the password so hopefully my account is secure. I deleted my AIM contacts so there is no one to spam. I use yahoo for my email and after another friend's account was hacked I deleted my contacts from the cloud to protect family and friends if I ever get hacked.

Assuming the full scans are clean which i expect, how did this happen? Brute force attack on AOL? Or more likely the fact that I use the same username and password for as many logins as I can?

I am currently updating all my passwords to protect myself. What if the hacker starts posting on Anandtech forums in my name, GASP!?

My ex gf had her AIM sending out crap.

I ran 2x virus scans (NOD + Kaspersky), Malware Bytes, SuperAntiSpyware, and we could not find anything after running them over and over. In the end we changed the pwd and her account was back to normal.

Not sure if that will help. Just change it again. I suspect it's just a bot.

Probably spoofed.
