It just means some compromised computer is send spam with your email address in the 'from' field. It doesn't mean your computer is involved or ever has been. You address has been harvested to receive spam, probably from malware in the computer if someone you emailed, and was randomly chosen as tge sender.

It's common, and most peolle know that. So ignore it - it'll probably die down after a few days. But if it doesn't you may have to change your email address.
