scanning and repairing a worm virus

I have received complaints that I have been sending emails with no sense to people.  I received a notice from a postmaster that they detected the following virus in my email message:

Worm.SomeFool.Gen-2 and W32/Netsky-B

I have an updated Norton software but have not detected these virus.

How can I detect the virus from my computer and remove these?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have you ran your anti-virus in Safe Mode?
Please clear all Temp Files (including Internet Explorer) and do so if you have not.
As backup assurance I would run another anti-virus suite such as Kaspersky (In Safe Mode as well) to see what it locates.
If you have Netsky this would detect and remove it.

Run it to find out if you have it or not, sometimes resident antivirus doesn't work well in detecting a virus once the virus is already in the system.

Please Download Removal Tool:

Save the file to a convenient location, such as your Windows desktop.
Double-click "Antinyxem-EN.exe" to start the removal tool.

The program will scan all running processes, and then you will be able to click the Scan button.
Click Scan to begin the tool, and then allow it to run.

Afterwards run Panda's ActiveScan for good measure:
I would guess that the virus is not on your system.

These days, almost all viruses use fake addresses for the "return" field. That way, the recipient has a hard time notifying the person who really has the infected PC.

If the above scan have not shown a virus on your machine I would feel pretty confident that you have nothing more to do or worry about.

If the bounce messages/complaints you got have a complete header with them you can sometimes figure out what IP address they originated at. It will prove that they did not come from you, but other than that there isn't a whole lot you can do.
