two explorers?

[bluerave]

My system was running terribly slow, and i noticed in the Task Manager under Processes there were two Explorers listed, Explorer.exe and Explorer.EXE, i noticed the Explorer.exe was taking up 100% CPU and 3MB memory. I have never seen this before, what is it?

Do you have DlDer.exe on your machine?

If it's a trojan check this URL

trojan

i have a 30k explorer.exe in C:\WINDOWS\explorer, but i couldnt find DlDer.exe

its also in my startup.

so i deleted it and removed the registry key.

thanks a bunch

yep im agreeing with thse previous folks. Im thinking of that dlder.exe trojan.

This trojan places one of the following files on your machine:

c:\windows\dlder.exe

or

c:\windows\explorer\explorer.exe

dont confuse this with the proper explorer.exe that should be there: c:\windows\explorer.exe
