It does? Bad news. Your account has been 0wned. Right now, before you do anything else, change the password and the secret question and do a thorough malware scan of your system. But there may well not be any malware on your system; and whether you find malware or not, it's no proof of the origins of your GMail Filter Virus.
What's a GFV you ask? some program has taken control of your GMail account and added a number of filters to turn the account into a spam proxy. When your GMail account receives e-mail sent to certain e-mail addresses, it forwards those messages on to other e-mail addresses. The point is to have your account "launder" the spam so as to hide its origins and increase the chance of it being delivered.
