AV-beta-release-1

We’re pleased to announce that a new beta version of ImunifyAV, version 5.3, is now available. The following features are new in the v5.3 beta release:

  • cgroups for Malware Scanner
    Extended resource limitation mechanics supports cgroups providing better control over resources in the  Malware Scanner on CentOS 7, 8 and Ubuntu.

Let’s review the changes. 

cgroups for Malware Scanner

ImunifyAV v5.3 utilizes cgroups for the CPU and IO resource management during on-demand and background scans. It limits file-system and CPU load according to configured “intensity level” avoiding spikes and smoothly spreading the load.

That is useful for non-CloudLinux OS systems where LVE is not available. Earlier CentOS 7/8 systems required CFQ scheduler to be available for ionice priorities schedule. Now, ImunifyAV v5.3 doesn’t depend on CFQ. Further installations on Debian systems will also rely on cgroups support for resource management.

Additional information

ImunifyAV v5.3 includes 30 tasks and 11 bug fixes.
