I have a problem with what I think is a trojan virus. Every week or so I get a file on my desktop named ' ~ ', I have opened the file using MS Word and can make out addresses form my e-mail address book. I have scanned my computer and Outlook Express with McAfee, AdAware and NoAdware, but the file reappears. Is the contents of my address book being sent each time and how can I fix this.

thanks in advance
