Ok, this is why I asked these questions.
Based on what I have heard as your replies, you have no evidence whatsoever that MM's newsletter gave you a virus. The fact a virus monitor triggered while you were manipulating the newsletter does not even casually show a relationship. Virus protection programs can find things well after they are established on your machine.
If the virus protection had indicated that MM's newsletter contained the virus, that would be one thing. But that's not what I am hearing.
You had a virus, and you read MM's newsletter. That is all we can safely assert at this time.
Thanks for the analysis Laz. As the government always says, I was passing the info along out of an abundance of caution.
