Attacked!

A few minutes ago, I received a guestbook entry with a link to the url http://picocouple.oldledy2001.net/index.html. Curiously, I clicked on the link, only to find out that it redirects to a page on http://xearl.com/ which contains a threat detected by NOD32 as "Win32/Agent.NDA trojan". The site xearl.com itself has the message: "This site is closed."

The attack was from IP Address : 80.50.82.90 which rosolves to :  Wroclaw, Dolnoslaskie, Poland.  (with 94% certainty)

This is nothing new, but I just wanted any web administrators out there, to be aware!

I'm not sure if this was an bot since I recently installed a CAPTCHA control.
