I had a Trojan thing recently, early spring, after not having anything for several years, the worms the last I recall. Norton isolated it quickly, and I was able to delete. What surprised me was its appearance without a download. I didn't know a Trojan horse could enter without clicking on some kind of download. The secret is updates, and a firewall. I methodically check in with my Norton Live updates.
When you get the name of this one, please post.
