A reader wrote in about this over the weekend, but I was mostly offline and didn’t see the email until this morning. For whatever it’s worth:
The NY Times reported on Sunday afternoon that an unauthorized advertisement on their site was malware. Readers of their website had seen a pop-up box warning them about a virus with then directed them to a site claiming offers of an antivirus software. The infection notice, and the resulting fake scans reporting dozens of infections, is a common ploy used by rogue anti-Virus software, and put NY Times web editors in the unenviable position of reporting on their own troubles.
