> Hi,
>
> We periodically run clamscan on one of our servers and it is producing a warning and an error log message for a certain file but the log messages do not contain the file name. How can I find out which file causes the warning and the error? I tried removing `--infected` and this causes the names of all OK files to be printed, but the name of the file that causes the warning/error is not logged.

> LibClamAV Warning: SWF: declared input length != compressed stream size, 893472074 != 9
> LibClamAV Error: scanzws: LzmaInit() failed
>
> We think the file type magic wrongly detects a SWF file but without knowing which file we can not address this in any way.
