My anti-virus keeps informing me it has blocked an "exploit blackhole exploit kit."

I e-mailed the ad companies to see if they're running any suspicious campaigns.

Just got an e-mail:

Hi Walt,

I believe we found the ad that was causing this and blocked it this morning. Please let me know if your readers continue to see these messages.

Thanks,
