Received spam email that appears (based on headers) to have originated from this domain. The email contained an attachment with a virus in it. The message was referenced an email address with my company used for support tickets but it did not contain any details, usernames, signatures, etc. I realize email from a site is not the same as the website but based on this I would avoid both as the site appears to be compromised.
