A couple of sites that may help you (hopefully virus-free).. http://www.iamnotageek.com/a/dl.exe.php http://securityresponse.symantec.com/avcenter/venc/data/backdoor.nthack.html It seems that dl.exe (and its aliases) don't attack .exe files, but hacks into your e-mail addys and the like (and other nasty vandalish things). So if your .exe files are infected it's with a different virus... Cheers, Diolma
