I believe you will gain something after reading this article on how to install Clam AntiVirus under Linux. Let's take a look at it.

Clam AntiVirus is an open source (GPL) antivirus toolkit under UNIX designed for email scanning on mail gateways. The toolkit provides a number of utilities, including flexible and scalable monitors, command-line scanners, and advanced tools for automatically updating databases. The core of the toolkit is the shared library of antivirus engines that can be used in a variety of situations.

Use yum to install clamav$ sudo yum install epel-release-y # EPEL library to include ClamAV$ sudo yum install-y clamav12 modify scan configuration file $cd / etc/clamd.d$ sudo cp scan.conf scan.conf.bak # create configuration file backup $sudo vim scan.conf123

The main changes are as follows:

LogFile / var/log/clamd.scan # specify log location LogFileMaxSize 20m # log maximum 20m, default scroll override LogTime yes # log recording time LocalSocket / run/clamd.scan/clamd.sock # local socket communication file MaxThreads 20 # maximum number of threads running at the same time ExcludePath ^ / proc/ # scan exclusion path, need to write with regular expression, one path to write one line If you don't write, it will scan all locations in the entire / root directory by default. OnAccessIncludePath / opt # specifies the folder (and internal subfolders) to be scanned, with a path of 1234567 per line.

After specifying the log storage, you need to manually create the log file and modify the permissions

$sudo touch / var/log/clamd.scan$ sudo chown clamscan:clamscan / var/log/clamd.scan12 create clamd backend service $sudo vim / etc/systemd/system/clamd.service1
