Today’s virus is the W32.sobig.F@mm virus which is a mass emailing virus with subjects such as “wicked screensaver” and “your application.” Symantec has information here.
Not as serious is the Amish Virus which operates by an Amish person saying to you:
“You have just received the Amish virus. Because we don’t have computers this virus works on the honor system. Please delete all the files from your hard drive and manually forward this virus to everyone on your mailing list. We thank thee.”
