[clamav-users] How to recompile with -fPIC?

Sun Jun 28 21:53:24 UTC 2020

Hi, Ged and Micah.

Thank you for the answers. I've tried following the steps that Ged told me (1. Delete... 2. Extract... 3. Change... 4. Run the following commands...), and I've installed Clamav properly. I've configured clamd.conf and freshclam.conf; I've configured on-access scanning on clamd.conf; I've programmed automatic scans with crontab (clamdscan command); I did a little script to run when a virus event happens (to ask me if I want to delete the virus or move it to a folder), and I created log files for the programmed scans, the database updates, the on-access scanning and the virus events. For me, that's quite enough. :-)

I haven't found any virus on my laptop. Now, I would like to test the virus event on the programmed scans and on-access scanning, to be sure that they work. Can you help me?

Thank you very much.

Alberto
