Hi,

Have you verified that the directory /var/log/clamav exists and the user you are running freshclam as can write to it?

cgakers commented 7 months ago

Rob,

Duh… I assumed since the install freshaclam portion ran without error; it was created. Saw freshclam running in process log.

Now clamscan hangs with no output even with -v. Not sure what is happenening. I have removed and reinstalled several times.

clamscan does take a few minutes to load the signatures, I would expect it to be longer on a raspberry pi. Could you try this

  1. Save 'X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*' to a string (no newline).
  2. run the command "clamscan -d /bytecode.cvd

The bytecode.cvd signature file is very small and should load really fast.

Also, could you run with '--debug' and upload the output?

Thanks, Andy

After a reinstall I get this when I now run freshclam ???

And this that I get when I try to make the string variable assignment:

$ @.[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H' -bash: **@.**[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H: command not found

It has been a long time since I have done this sort of thing, so I could be messing it up !

You don't want to try and run that, the eicar string is used to test antivirus products. It should signature, but won't cause any damage. For a better explanation, check out https://www.eicar.org/download-anti-malware-testfile/

In your case, freshclam is not able to download signatures because your version of freshclam is too old. Our supported versions are on our downloads page here https://www.clamav.net/downloads. If there isn't a version there for your platform, your best bet is to contact your package maintainer or build from source.

ragusaa commented 7 months ago

If you are going to download from our downloads page, I would suggest going with 1.3 (latest), because 0.103 will be EOL'd later this year.

No problem. I am going to close this issue, but let us know if you have any other issues getting set up.

Thanks, Andy

It just occurred to me that you could also try our docker image. https://hub.docker.com/u/clamav Documentation is here https://docs.clamav.net/manual/Installing/Docker.html
