When I tried to visit one of the other threads like female a script or something was trying to download a virus into my computer.  It's an advertisement that does this and I think it's either a flash or a javascript.  please recommend of checking

I'm getting similar, where it's doing a complete page redirect for any of the art pages.

Hint: If you guys want anything done about this, answer >>4. He's the host.

Its redirecting to a prodefender site on both firefox and safari.

I'm using firefox with ABP and I just had that happen going to one of the boards. I noticed one of the animated ad banners said "The Youtube of porn is here," but I don't think the second one even displayed before a popup spontaneously opened itself, resized the main window, and redirected me to
http//gloriousantivirus20/...
(don't go there, obviously)
which pretends to look like the My Computer window with a series  of those 'omg-ur-totally-infected-install-this-or-else' dialogue boxes that interrupts you if you attempt to close the window or leave.

the javascript also popped up in Opera, luckily you can tell Opera to stop executing scripts on a page.

please get rid of whatever is doing that.

Alright, thanks for the infos. I've gotten enough data on here and in IRC that the host should be able to pinpoint the exact problem. Until that has happened I've temporarly disabled the ads.

This is why adblock is your friend.

NoScript.  'Nuff said.

Or you're making shit up, since the only way you could've gotten a virus from this through firefox is by actually running the executable the redirect tried to make you download.

You have no clue whatsoever how advertising online works. Ads themselves are provided by a third-party, like Google AdSense, AdBrite or similar. These provide the interfaces for clients to set up ads, configuration of those, payment flow, etc. They also provide an interface for advertisement carrying sites like fchan, which allow those sites to select the dimensions and types of ads (text, image) they want to display. Both of these things are largely automated.

The crux is the interface to the clients as they get to pretty much define HTML themselves which is then to be delivered on other sites. All advertising intermediaries have some sort of filtering on that to block too obvious abuse. However not all of them are of the same quality. Now you could say "Well gee, just choose one that has better filtering!" However that isn't possible, since many advertising intermediaries won't allow porn-related sites to use them.

As such the only thing fchan can do is keep an eye on things and report to the intermediary if a specific ad slipped through their filtering. Which is also why action on these things isn't very fast, since without knowing exactly which ad is problematic, it is impossible to report it.

TL;DR: Look how dumb you are.

I never had that warning, i use Firefox with Adblock Plus and Noscript extension.
Its kinda restrictive but at least its a way to make sure that YOU can decide what runs on your machine.
