I bought AnyDVD HD from RedFox in July 2016. I'm not sure whether it is still the case, but back then a Visa card was required so I used one belonging to an old, dormant account. The card itself was valid from only a few months before that purchase, and I hadn't (and still haven't) used the same card for anything else. A couple of days ago I noticed a fraudulent transaction on the same card. The card had been used to pay Facebook in a "legitimate" transaction, but I hadn't authorised it. Royal Bank of Scotland's fraud team are investigating but there is a fairly clear link back to RedFox I'm afraid.
