### clamscan

`clamscan` writes all regular program messages to stdout and errors/warnings to stderr. You can use the option `--stdout` to redirect all program messages to stdout. Warnings and error messages from `libclamav` are always printed to stderr. A typical output from `clamscan` looks like this:

    	/tmp/test/removal-tool.exe: Worm.Sober FOUND
    	/tmp/test/md5.o: OK
    	/tmp/test/blob.c: OK
    	/tmp/test/message.c: OK
    	/tmp/test/error.hta: VBS.Inor.D FOUND

When a virus is found its name is printed between the `filename:` and `FOUND` strings. In case of archives the scanner depends on libclamav and only prints the first virus found within an archive:

    	zolw@localhost:/tmp$ clamscan malware.zip
    	malware.zip: Worm.Mydoom.U FOUND

TIP: You can force clamscan to list all infected files in an archive using -no-archive (this option disables transparent decompressors built into libclamav) and enabling external decompressors: -unzip -unrar....

    	zolw@localhost:/tmp$ clamscan --no-archive --unzip malware.zip
    	Archive:  /tmp/malware.zip
    	  inflating: test1.exe
    	  inflating: test2.exe
    	  inflating: test3.exe
    	/tmp/clamav-77e7bfdbb2d3872b/test1.exe: Worm.Mydoom.U FOUND
    	/tmp/clamav-77e7bfdbb2d3872b/test2.exe: Trojan.Taskkill.A FOUND
    	/tmp/clamav-77e7bfdbb2d3872b/test3.exe: Worm.Nyxem.D FOUND
    	/tmp/malware.zip: Infected.Archive FOUND
