I got an email from a user, stated that while visiting my website, his anti-virus software picked up a virus called Exploit.Html.MhtRedir.Gen. He cleaned his system, visited my site, and picked it up again. I should note that I have not received any other complaints, nor has my own up-to-date McAfee VirusScan picked up any such virus.
Nevertheless, this is very disturbing. What should I do?
