We've been getting spam from someone called "Medic.Canada" for weeks. We get 2 or 3 spam emails daily. I spoke to verizon-yahoo about it and they said to mark the email as spam and it would eventually be filtered out. That hasn't happened although I've been marking it as spam for several weeks.
In the past few days I discovered that I couldn't connect with the verizon-yahoo server to get email and I kept getting an error message that didn't give an error code and said it was an unspecified error. Then, suddenly, while I was on the web, I heard the sound that a new message came in. When I looked I saw there was an email from "Medic.Canada" that was less than 1 hour old that came in along with other emails.
I decided to scan the outlook express email folder with our antivirus. When I looked in the email folder I was surprised to see that it seemed that Medic.Canada had somehow managed to have many listings in the main folder (that also contains inbox.dbx, etc.) but these files were .eml files -- such as "Buy cheap meds.eml"
The scan didn't show any virus but this seems pretty suspicious to me.
