Antivirus Settings for Linux Profile


The antivirus section lets you configure real-time monitoring, custom scans, scan schedules, exclusions and more.


Configure antivirus settings in a Linux profile

  • Click 'Configuration Templates' > 'Profiles'
  • Click on the name of a Linux profile
  • Click 'Add Profile Section' then 'Antivirus' (if you haven't yet added the AV section)
OR
  • Open the 'Antivirus' tab and click 'Edit' if it was already added

The antivirus settings screen will open:



It contains three tabs:

  • Scanner Settings - Configure real-time scans, manual scans, scheduled scans and exclusions.
  • Scan Profiles - Create antivirus scan profiles that define specific folders, drives or areas to scan. Once saved, you can apply a scan profile to scheduled scans.
  • Scheduled Scans - Timetable scans to be run on managed devices according to a selected scan profile.

Configure Scanner Settings for CCS for Linux


The 'Scanner Settings' area contains four sub-tabs:

  • Exclusions - View and manage items which will be skipped by virus scans.


Realtime Scanning

  • Click the 'Realtime Scanning' sub-tab under 'Scanner Settings'


Please note: The real-time virus scanner is not supported on Debian. The settings in this screen do not apply to Debian devices.



Real Time Scanning Settings - Table of Parameters

Form Element

Type

Description

Real time scanning

Drop-down

Enable or disable the background virus monitor.

  • On Access – Files are scanned before they are allowed to run. Threats are detected before they get a chance to execute (Default)
  • Disabled - Real-time protection is switched off. Files are allowed to run without first being checked for threats.

Do not scan files larger than (MB)

Text box

Maximum file size that the antivirus should attempt to scan. Files larger than the size specified here are not scanned. (Default = 20 MB).

Keep an alert on the screen for (seconds)

Text box

How long threat notifications should stay on-screen if not dismissed by the end-user. (Default = 120 seconds)

Automatically update virus database

Checkbox

CCS will check for and download the latest virus database updates on system start-up, and subsequently at regular intervals.

  • Disable this option if you do not want CCS to automatically check for updates.

(Default = Enabled).

Automatically quarantine threats found during scanning

Checkbox

Threats will be encrypted and moved to a secure holding area where they can cause no harm. You can review quarantined items and delete, ignore or restore them.

  • Disable this option if you do not want threats to be moved to quarantine.

(Default = Enabled)

Show notification messages

Checkbox

Choose whether or not a notification is to be shown to the end-user, whenever CCS identifies a threat and moves it to quarantine.


(Default = Disabled)

Enable heuristic scanning

Checkbox

Enable or disable heuristics scanning and define the scan level.


The scan level determines how likely the scanner is to classify an unknown file as a threat.

  • Low - Lowest sensitivity to detecting unknown threats / generates fewest false positives. The 'low' setting combines an extremely high level of security and protection with a low rate of false positives. Comodo recommends this setting for most users. (Default)
  • Medium - Detects unknown threats with greater sensitivity than the 'Low' setting but with a corresponding rise in the possibility of false positives.
  • High- Highest sensitivity to detecting unknown threats / increased possibility of false positives.

(Default = Enabled with 'Low ' option)


Background Note: Background. Heuristics identify previously unknown malware by checking whether it contains code typical of a virus. If it is found to do so then the application deletes the file or recommends it for quarantine.


Heuristics is about detecting 'virus-like' attributes rather than looking for a virus signature which exactly matches a signature on the blacklist. This allows the engine to detect new viruses even if they are not in the current database.


Manual Scanning

  • Click the 'Manual Scanning' sub-tab under 'Scanner Settings'
  • The options you set here will apply to manual scans on the endpoints on which the profile is active.
  • A manual scan is one you run 'on-demand' on selected files, folder or drives. Manual scans can be launched from 'Security Sub-Systems' > 'Antivirus'.

Form Element

Type

Description

Do not scan files large than (MB)

Text box

Maximum file size that the antivirus should attempt to scan. Files larger than the size specified here are not scanned. (Default = 20 MB).

Scan archive files

Checkbox

CCS scans archive files such as .ZIP and .RAR files.

  • Disable this option if you don't want archive files to be scanned.

(Default = Enabled).

Automatically update virus database before scanning

Checkbox

CCS will check for and download the latest virus database before starting an on-demand scan.

  • Disable this option if you do not want CCS to automatically check for updates.

(Default = Enabled).

Enable cloud scanning

Checkbox

CCS detects the very latest viruses more accurately because the local scan is augmented with a real-time look-up of Comodo's online signature database. This makes it possible to detect zero-day malware even if your local virus database is outdated. (Default = Disabled).

Enable heuristic scanning

Checkbox

Enable or disable heuristics scanning and define the scan level.


The scan level determines how likely the scanner is to classify an unknown file as a threat.

  • Low - Lowest sensitivity to detecting unknown threats / generates fewest false positives. The 'low' setting combines an extremely high level of security and protection with a low rate of false positives. Comodo recommends this setting for most users. (Default)

(Default = Enabled)
