Hi Mickey, I've set OnAccessMaxFileSize 1000M.
Instead of "Tue Aug 30 10:38:59 2016 -> ScanOnAccess: Max file size limited to -1 bytes" I get: "Tue Aug 30 12:44:08 2016 -> ScanOnAccess: Max file size limited to 1048576000 bytes" I still don't see any entries when I open up files. I should note that I also set this selinux boolean a couple of reboots ago. antivirus_can_scan_system --> on in selinux as well. I also tried simplifying the configuration to this, and running clamd manually. """ LogClean yes LogSyslog yes LogVerbose yes LocalSocket /var/run/clamd.sock Foreground yes ScanOnAccess yes OnAccessMountPath / OnAccessExcludeUID 0 """ When I execute the following command: clamdscan minuscule.pdf In the logs I see Aug 30 13:20:17 localhost.localdomain clamd[13472]: /home/<snip>/Documents/minuscule.pdf: OK When I open the same file with evince, I get nothing from clamd. Note that I've been sticking to small files to avoid hitting the default file max (5m).
