If you visited Topaz' website lately you may have received a [false] malware warning. I discussed this with them today and here is their reply:

Although Google still flags the site as suspicious at the time of this writing, you should not experience any problems using the site. There should also be no unauthorized third-party redirects or advertising banners at this time. Email me directly if you experience otherwise.
Today we're contracting an external security company to harden up our server security and prevent attackers from inserting their code in the future. We're taking this very seriously and taking every precaution to ensure that this doesn't happen again.
Thanks for your understanding and sorry for any inconvenience this may have caused. Please contact me at security <@> topazlabs.com if you have any questions.
