Is anyone else being redirected when reading articles here at DKOS?

A user at Daily Kos has experienced site redirects to a suspicious page resembling McAfee Security Scan, possibly a malware scam. The issue mostly arises when revisiting the same article or during ad refreshes. Using Firefox’s HTTPS-Only Mode seems to help, triggering a warning during attempted redirects. The user questions whether they should alert the Help Desk.
