ImunifyAV(+) 4.8 released

May 25, 2020 4:24:44 PM / by Inessa Atmachian


We’re pleased to announce that a new version of ImunifyAV has been scheduled for gradual rollout from our production repository and will be available for all customers in about two weeks or less. If you’d like to get it earlier, see instruction at the end of the post.

The ImunifyAV version 4.8 release introduces the following changes and features:

  • Malware scanner UI improvement
    A Cleaned malicious files chart, badge with a number of missed events in the History tab, and links to History event.
  • An ability to enable scan for an end-user
    Configurable options to enable/disable “scan” action in the UI of the end-user.
  • Better Resource usage control
    Scan list preparation is under LVE / nice limitations too.

Let’s check the details regarding new features:

Malware scanner UI improvement

We introduced a couple of enhancements in the UI of the Malware Scanner. 

The first one is the badge in the History tab. It shows the number of missed events in the Malware Scanner’s History. Now you won’t miss any automatic actions applied to infected files since they will be listed in the History tab and shown in the badge.


Enable scan for end-users

We’ve been asked a lot for the way to enable “scan” action for end-users so they could run a scan at any time on their own.


This option is available in the config file or via the command-line interface. 

With respect to resource consumption, all user scans are scheduled using a single queue. Thus, multiple scans requested by users will not affect server performance.

Note: scan of end-users is disabled by default.

To enable this setting via the command-line interface, use this command:

imunify-antivirus config update '{"PERMISSIONS": {"allow_malware_scan": true}}'

Better Resource usage control

The entire malware scan process is under strict control regarding CPU and memory usage. Now it manages the resource usage intensity during the list preparation, which will be beneficial during a scan of a sizeable subset of files (thousands of user account, millions of files).
