I was on Facebook and I had just opened up a new tab and typed in the address to get here.. I was looking at the recent posts and then my download's box popped up (firefox) saying a PDF was opening called docs.pdf (it didn't open)
Then my anti virus came up saying it found 3 infections and quarantined them.
I didn't click any links.
I really hope that it's not this website and I'm pretty sure it's not. The only thing i can think of would be Facebook, but the only thing i had open on there was the Mafia Wars app, but I've had that for a while and nothing like this has happened before.
I opened up my history to see what URL might have caused it, and there are a few suspicious items..
pdf.php - http://stats-analytics.cn/sp/pdf.php?f=all
(DON'T CLICK IT. THE LINK MAY CONTAIN ADWARE/SPYWARE)
links.php (dang.. i clicked Delete instead of Copy... cant share the link)
