Since you've gotten several informative answers to your specific problem I think it's incumbent upon me to point out an even better solution: Stop using Outlook for email ASAP. It's a virus magnet. There are several good free email clients for windows - Pegasus ( http://www.pmail.com/ ), Foxmail ( http://fox.foxmail.com.cn/english.htm), and my fave the adware Eudora ( http://www.eudora.com/ ). Not only are any of these easier to use, but simply by not using Outlook (for email) you automatically protect yourself against 95% of the latest viruses. The sooner you take the effort to switch the easier it will be. - Users can unsubscribe from this list by sending email to 24hoursupport-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field OR by logging into the Web interface at http://web.tampabay.rr.com/spider1/24hrsupport.htm.
