The unload option of clamscan.exe (--unload/-u) seems to be broken since v0.90.

I assume it can be specified in combination with the kill option, under v0.88.7 it worked well, under 0.90 I get an errorcode 40;

Code:

c:\Program Files\ClamWin\bin\clamscan.exe: unrecognized option `--unload'
ERROR: Unknown option passed.
ERROR: Can't parse the command line

Error also occurres when specified with the short notation (-u).

Is this intended?

TIA,
Laurens

you must have an old clamav binary or installed it from another source, clamwin's distribution of clamscan.exe version 0.90 understands --unload. Because it is the default option we would have had plenty of bug reports by now. Please check the version of clamscan.exe by passing --version parameter.

Also I suggest you uninstall clamwin, and then clean c:\program files\clamwin folder and reinstall.

Strange...

I checked the version and it is OK: 0.90

Code:

C:\Program Files\ClamWin\bin>clamscan.exe --version
ClamAV 0.90

Afterwards I completely removed the app (uninstall + manual delete of leftovers, in Program Files as well as Docs & Setts) and re-installed ClamWin. Still the same error.

Here is the command that fails:

Code:

"c:\Program Files\ClamWin\bin\clamscan.exe" --database="C:\Documents and Settings\All Users\.clamwin\db" --log="%REPORT%" --verbose --infected --tempdir=d:\temp --move=c:\clamav-infected --recursive --memory --kill --unload --exclude=^.*\.avi --exclude=^.*\.mpg --exclude=^.*\.mpeg --exclude-dir=^.*\\downloads\\complete --exclude-dir=^.*\\downloads\\.*temp --max-mail-recursion=20 --max-space=20M --max-ratio=0 --max-dir-recursion=200 --unrar="c:\Program Files\WinRAR\UnRAR.exe" --7zip="c:\Program Files\7-Zip\7z.exe" "%TDIR1%" "%TDIR2%" "%TDIR3%" "%TDIR4%" "%TDIR5%" "%TDIR6%"

The TDIRs are set in the batchfile the command is executed from. I use psexec to execute ClamWin (because clamscan doesn't offer a parameter to specify the priority), but I tested without psexec and it gives the same error.

Exactly the same command (same batfile) worked fine for 0.88.7 (I noticed the failure when I didn't receive scanreports anymore since I updated ClamWin last monday). When I leave out the --unload, everything is OK. I don't need to specify anyway as it is the default, but I think the error is weird.

it's --kill not --unload (you have both in your command line)

no alch my fault, --unload should be accepted as argument, I've fixed it in svn

Sherpya: what would be the difference between --kill and --unload ??

--kill terminates infected processes, --unload unload infected libraries from processes so it's a bit dangerous
