Hello Friends, If you are a Clamav user, it may be useful to you. Newer version of Clamav comes with an On-Access Scanner. Here are my set up steps: Log in as root: su -l root Then, create a new directory /root/quarantine/ : cd ~ mkdir quarantine logout Then, in file /etc/clamav/clamd.conf, add these lines: OnAccessExcludeRootUID yes OnAccessExcludeUname clamav OnAccessIncludePath /tmp/ OnAccessIncludePath /var/tmp/ # additional path to be scanned. OnAccessExcludePath /some_path/ # additional path to be excluded. OnAccessPrevention yes Then, run: sudo systemctl enable clamav-clamonacc.service sudo systemctl start clamav-clamonacc.service Done but I do not know whether it works better than other virus scanners. If you use other type of virus scanners such as Malware Detect, etc, their jobs may overlapped. So please add your opinions as well.
