I posted this in connection with a malware question in the malware forum a couple of days ago, but that thread seems to have disappeared - at least, I can't find it. I'm thinking it's more of a software problem, anyway. I'm a relatively new computer user running Vista, and what I don't know could fill the phone book, but here's my problem. I checked my DNS cache and found three or four dozen entries - all are highly suspect-looking sites, none of which I've ever visited. They seem to all(?) be listed among the hundreds of sites listed in my registry in relation to my Spybot protection. But isn't the DNS cache supposed to only hold sites that I've actually visited before, or tried to visit? As I said, I've never been to any of those sites. In addition, I tried clearing the cache, via Command Prompt, ipconfig/flushdns, but it didn't work. It says the attempt was "successful," but when I look in the cache again they're all still there. So: 1. Why are sites I've never been to listed in the DNS cache? 2. Why aren't any sites that I HAVE been to listed in the DNS cache? 3. Why can't I clear the cache? Thanks in advance for any help!
