Log File growing urgent Please

Hei,
Log file is growing very fast (Log file size is now more then 3GB and data
file size is not more then 1GB) and i want to shrink log file using this
command
use modbt
go
DBCC SHRINKFILE (modbt, 20)
go
OR
DBCC SHRINKFILE (modbt_Log, 20)
but getting error
Server: Msg 8985, Level 16, State 1, Line 1
Could not locate file 'modbt_log' in sysfiles.
DBCC execution completed. If DBCC printed error messages, contact your
system administrator.
I run sp_helpfile and get result
Name fileid Filename Filegroup Size Maxzie
growth usege
1 Axc_Data 1 D:\....\Modbt.mdf Primary 850688KB unlimited 10%
data
2 Axc_log 2 E:\....\Modbt.mdf Null 3575936KB unlimited
10% log
I run DBCC LOGINFO('modbt') and get STATUS '2' for 40 line but no one using
database that time. STATUS '0' for more then 300 line.
When i run DBCC SHRINKFILE (Axc_log, 20) then got
DbId Field CurrentSize MinimumSize Used Pages EstimatedPages
