Back in early December my brother downloaded some dodgy keygen for a VST plugin from some website and ended up getting a bunch of issues with his PC, he ran malware bytes and bitdefender and assumed it was gone, but now for the 3rd time my ISP is sending me letters/emails saying “gamut” is still on a device on our network, but I don’t know which. I’ve scanned my desktop PC, he’s scanned his, my laptop isn’t on, there’s no other laptop in the house, could it be an android phone/iPhone? I’m lost on what else to try, nothing seems to find a virus or malware, but my ISP is convinced it’s still on the network.
