One of those messages that you "forwarded" (which you should never do)probably had a nasty enclosed. It could be a trojan rather than a virus. Do you have an antispyware program on your computer like "Malwarebytes" its free. Suggest you download it, install it, update it then run it. Another good one which complements Malwarebytes is Spywareblaster, Its always running in the background and keeps these nasties from loading. You just have to update it weekly or so and its free as well. What service package of XP do you have (hopefully XPSP3) To find out right click on "my computer" select properties and that info should be in the box that appears

So perhaps this email is stuck in your Outbox? If so you could click on Outbox and double click on the offending email and delete it. Seems like it has a non recognised address on it.

First of all the email you quoted alludes to the postcard virus, which is a real virus that has been around since last summer. However, the body of your email contains false and incorrect info. It is a hoax. I have linked to Snopes.com for clarification of your email. If you had read to the bottom of your link, you would have seen this info also. One should always check out these mass warnings at Snopes. The real problem is that you included a link that was in your email. It turns out that the link is benign, but it very well could have sent people to an infected web page. It's very common for the bad guys to do this type of thing. I know you meant well, so please don't take this personally and please don't stop posting. Caution is the operative word along with Snopes.com. Here is a link that might be useful: The other email warning

The writing style of this message has all the signs of it being a hoax. A lot of these 'virus warnings' contain viruses themselves because that is the BEST way to disguise a virus and get people to "send it out to eveyone they know". Anytime you get anything that says to forward it to everyone you know - DON'T. That is the first clue. BTW that message you received has been going around for years. That is why is says discovered "yesterday" in the text, to keep it fresh and active so people send it on and on, and on.....
