Anybody ever hear of "dlder.exe" ? One of my younger siblings downloaded something infected cause earlier today whenever I tried to get into my computer or control panel, it would give me errors telling me to reboot my system cause explorer was having problems. So I rebooted and lo and behold Norton finds it trying to run itself in the windows start menu. I quarantined it so I could examine it. All Norton tells me is that its a backdoor trojan. I deleted it and all my errors are gone. Anybody have any info on this?
