I have had an email and now one of your letters claiming to have found Ponyloader on my system. My computer is clean. Squeaky clean. I have done deep scans with comodo and Malwarebytes. Nothing. A bit of research shows this to be a possible dead trojan. The only other device I have is a Neos camera which I have temporarily disconnected. The letter and email gives no specific detail of which device it thinks is infected. Going by the number of these incidents I see reported on here, I believe one of your 'not-for-profit' organisations is getting false positives, or maybe they have a problem. In anycase, I shall be dumping your service once this corona stuff is over.
