My AVG scanner detected a threat in www.zenphoto.org/support/topic.php?id=993.
Description: [i]Exploit Blackhole Exploit Kit (type 2073)[/i]

The title of the topic is [i] virus attack on my website[/i]

Maybe the posted code can still do harm.

Are you sure it is not overactive? What should be the threat in that old topic (the link shows a topic "Error pathurlencode" for me)?

Sorry, it should be www.zenphoto.org/support/topic.php?id=9939

And I guess it was probably a bit overactive ;-)
