I posted this screenshoot in the thread i created, it showed up just when loading gofuckyourself, so it's not a sig but a banner, as it doesn't always pop, just from time to time (i guess when the banner enters in the rotation).
Microsoft security essentials gave me an alert about Exploit:Win32/Pdfjsc.FG trying to infect my computer and blocked it, so yes, seems related to that acrobat error some of you saw.
