i tryed all ways but it's still scanning all my logs
This doesn't tell me what you tried and where, any suggestions I make would be guesswork.
I also asked about standard shield's sensitivity settings ?
What is the file name/s and location/s of the .log file/s causing the problem ?
What have you entered to try to exclude them, e.g. using wild cards C:\*\dcFolder\*.log, what ?
Where did you enter the exclusion string ?
I suspect, Program Settings, exclusions (assuming the syntax of the path is correct), if so this isn't where I said to exclude the files from on-access standard shield scan.
