[Atomic-S (OP)]

Something keeps accessing my Zip drive, for no apparent reason, all the time the computer is running. I found out, by pulling the disk out, that the using program is DrsCh.exe .  What is that? Is is supposed to be there? Does anyone know anything about it?

I'm not 100% sure but believe its a Trojan,backdoor virus

When you get something like this, the first things to do are to try scanning it with a virus checker and googling it.

When you google DrsCh.exe you'll see that all the hits indicate that it is a trojan, which is a pretty good indication (just one or two hits might be suspect, but when all, or the vast majority of them agree, it's a pretty safe bet)

According to the above there it has some extra problems. Also, another site listed it as a Backdoor-Trojan.
