os: windows 2000
virus software:symantec 9.0
description: when os start-up,the alarm is appearing,show that find the virus in the directory "c:\windows\system32",the name of file is "sosdrp.sys",the name of virus is hacktool rootkit.
after I show all files(include the hide file and protected files),I cann't find sosdrp.sys. maybe this file is produced by the virus process,but I cann't find the services,files,regedit, or process,and I cann't solute this virus by tradition way.
