The Economist:
On Oct. 31, 2015, one of economist.com’s vendors, PageFair, was hacked. If you visited economist.com at any time between Oct. 31, 23:52 GMT and 01:15 GMT, Nov. 1, using Windows OS and you do not have trusted anti-virus software installed, it is possible that malware, disguised as an Adobe update, was downloaded onto your PC.
According to Twitter, PageFair is an anti-adblocker. Those fuckers.
