Hello all,

I'm currently trying to figure out why cxs scan doesn't quarantine the virus it found

before that, it worked but seems like the signature was different

It looks like an unofficial eicar test. Try it using the official eicar file. Also, you do not appear to have --qoptions set in your cxs command line. I'm not sure how you've done that since it should be set to --qoptions Mv if the --quarantine option is set.

The eicar file is the official downloaded from eicar.org, but somehow clamav report it as that.
I'm using the clamav for cpanel, no customization on the configuration file.

here is the scan result using -qoptions Mv:
