The IP address where I work was listed on Spamcop due to viruses sending spam from one of our PCs. I found some viruses on one PC yesterday and removed them. The Spamcop listing was supposed to expire last night after I had left, which it did, but when I returned today it had been listed again. I checked the PC that had the viruses with AVG and Kaspersky and nothing was found, I also checked every other PC on the network with both AVs and still nothing. Anyone have any idea what else I can do to find what is causing this?
