My Norton Anti-Virus just finished a routine scan on one of my trading machines, and for the first time it found some infected files. I use Zone Alarm, so I'm not sure how I got them, but I could use some advise on what to do. My other machines which are behind a router seem to be okay. One of them is Trojan Horse, the item is kdll.dll. The other is W32.Badtrans.B@mm, item KERNEL32.EXE. Norton advised quarantine, so I had it do that (I don't even know what this means). I don't know anything about this stuff, and would greatly appreciate any advice on what to do. Thanks. PS I'm using WindowsXP if it matters.
