I hope someone can provide answers to a problem I've been dealing with for 2 months. I am using a program called Postini provided by my ISP. Each day I am inundated with messages from ISP that tells me that they have detected a possible email virus and have quarantined it. It is always going to someone or some company I have never heard of and sent by someone I've never heard of. At times, it will have our email address as the sender. A friend of mine received an email from me at his business which I did not send and his virus protector blocked it. I have read all about the Klez virus and SirCam. I have the latest McAfee Firewall and Home Computer antivirus programs. I've also downloaded Stinger, found a program called Autoupder which supposedly rids your computer of the Klez virus and I downloaded it. Each day I run the antivirus program and it says my computer is clean. Why then am I receiving 10 or more emails from the Postini program as well as others (Network Associates, Postmaster, etc) telling me that an email I have sent has a virus (I have not sent any emails since this problem started for fear that I may have a virus!) I contacted the techs at my ISP and they did not provide any help. They just told me as long as I had an updated antivirus program I didn't have anything to worry about. This is a daily occurrence. Can anyone help?
