How to configure antivirus scan settings in CCS for Linux

Click 'Antivirus' > 'Scanner Settings'

• CCS leverages multiple technologies, including real-time monitoring and on-demand scans, to keep endpoints totally free of malware
   
• You can set up the behavior of the antivirus scanner for different types of scans 
   
• You can also exclude files, folders and processes that should be skipped  by the scans
   
• The antivirus settings
   
  • Real time scanning
     
  • Manual scanning
     
  • Scheduled scanning
     
  • Exclusions

The antivirus settings

Click 'Antivirus' > 'Scanner Settings'

• The settings area lets you configure real-time scans, manual scans, scheduled scans and exclusions.
   
• The settings you implement here will apply to all future scans of that type.
   
• Items added to 'Exclusions' are omitted from all types of scan

Open scanner settings

• Open Comodo Client Security
   
• Click the 'Antivirus' tab
   
• Click 'Scanner Settings'

The virus scanner settings interface has the following tabs:

• Real Time Scanning - Configure the 'always-on' virus monitor
   
• Manual Scanning - Configure scanner behavior for on-demand scans
   
• Scheduled Scanning - Configure scanner behavior for automated-scheduled scans
   
• Exclusions -  View and manage items skipped by virus scans.
   

Real Time Scan Settings

Click 'Antivirus' > 'Scanner Settings' > 'Real Time Scanning'

• The real-time scanner is the 'always on' virus monitor which runs in the background, checking files when they are opened, copied or downloaded.
   
• The real-time scanning area lets you enable or disable the scanner and configure scan options. We highly recommend you keep the real-time scanner active at all times.

Configure real time scanner settings

• Click 'Antivirus' > 'Scanner Settings' 
   
• Click the 'Real Time Scanning' tab, if it is not already open 
  
  

Real-Time Scanning 

• Use the slider to activate or deactivate the real-time virus monitor:
   
  • On Access - Any file opened is scanned before it is allowed to run.
     
  • Disabled - Switches the real-time scanner off. 

Please note: Real-time scanning is not supported on Debian. This feature is not available on Debian. 

Detection Settings

• Automatically update virus database - CCS checks for and downloads the latest database at system start-up and regular intervals thereafter (Default = Enabled). 
   
• Automatically quarantine threats found during scanning – Select whether or not CCS should automatically take action against malware found by the scan (Default = Disabled). 
   
  • Enabled = CCS moves detected malware into an encrypted holding area known as 'quarantine'. Files in quarantine cannot run and pose no threat to your system.
    
    Click 'Antivirus' > 'Quarantined Items' to review quarantined files. You can restore items to their original location or permanently delete them. See this wiki to read more. 
     
  • ​​Disabled = CCS shows an alert when a malware is found, with its details. You can choose to clean the malware or to ignore the alert.
     
• Show notification messages - Alerts appear at the bottom-right of the screen whenever malware is found and moved to quarantine. Available only if 'Automatically quarantine threats found during scanning' is enabled. (Default = Disabled).  

• Heuristics Scanning Level - Heuristics is a technology that analyzes a file to see if it contains code typical of a virus. It is about detecting 'virus-like' attributes rather than looking for a signature which exactly matches a signature on the blacklist. This allows CCS to detect brand new viruses even that are not in the current virus database.
  
  The drop-down menu lets you select a sensitivity level. The sensitivity level determines how likely it is that heuristics will decide a file is malware:
  • Off - Disable heuristic scanning. This means that virus scans only use the 'traditional' virus database to determine whether or not a file is malicious.
     
  • Low - Least likely to decide that an unknown file is malware. Generates the fewest alerts. Despite the name, this setting combines a very high level of 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 but this also raises the possibility of more false positives. 
     
• Do not scan files larger than - Specify the largest file size that the antivirus should scan. CCS will not scan files bigger than the size specified here (Default = 20 MB). 
   
• Keep an alert on the screen for - Specify the length of time that virus alerts should stay on the screen. (Default = 120 seconds).

Click 'OK' to apply your changes. 

Manual Scanning

Click 'Antivirus' > 'Scanner Settings' > 'Manual Scanning'

The options you set here apply to all on-demand scans on your computer. For example, these settings are used when:

• You click 'Scan Now' on the home screen then run a full or quick scan 
   
• You scan an item by dragging it into the scan-box on the home screen
   
• You scan a file in the 'Run A Scan' from the 'Antivirus' menu

Configure manual scan settings

• Open Comodo Client Security
   
• Click 'Antivirus' > 'Scanner Settings' 
   
• Click the  'Manual Scanning ' tab 

Scan archive files - The scan will include compressed file formats such as .ZIP and .RAR files. Supported formats include RAR, WinRAR, ZIP, WinZIP ARJ, WinARJ and CAB archives (Default = Enabled). 

Automatically update virus database before scanning - Check for and download the latest virus signature database prior to running a scan (Default = Enabled). 

Enable cloud scanning - Improves scan accuracy by augmenting the local scan with an online look-up of Comodo's latest virus database. Cloud Scanning means CCS can detect the latest malware even if your database is out-dated. (Default = Disabled).

Heuristics Scanning Level - See the description above. 

Do not scan files larger than - See the description  above. 

• Click 'OK' to apply your changes.

Scheduled Scanning

Click 'Antivirus' > 'Scanner Settings' > 'Scheduled Scanning':

• The options you set in the 'Scheduled Scanning' tab apply to all your scheduled scans. See this wiki for help to create scan schedules. 

Configure scheduled scan settings

• Open Comodo Client Security
   
• Click 'Antivirus' > 'Scanner Settings'
   
• Click the 'Scheduled Scanning ' tab:

The options in this pane are similar to those for manual scanning settings, except for: 

Automatically quarantine threats found during scanning -  See the description  in the ‘real-time scanner settings’ section 

Show scanning progress - Displays a progress bar when a scheduled scan starts. Clear this box if you do not want to see the scan progress status (Default = Enabled).

• Click 'OK' to apply your changes.

Exclusions

Click 'Antivirus' > 'Scanner Settings' > 'Exclusions'.

• The exclusions area shows files and paths that you have chosen to skip during virus scans.
   
• CCS will not generate an alert for an excluded item, even if the item is rated as malicious in the global blacklist.
   
• Items may have been added to this list because you selected 'Ignore' at the scan results window, or because you added them to exclusions at an alert.
   
• Use this interface to add or remove exceptions.

Add and manage exclusions

• Open Comodo Client Security
   
• Click 'Antivirus' > 'Scanner Settings' 
   
• Click the 'Exclusions' tab:
  
  
   
• Click the 'Add' button. 
   
• There are two ways to choose the application that you want to exclude:

Browse Files... - Navigate to the file / folder you want to exclude in the left pane and move it to the right pane by clicking the right arrow:
 

Browse Running Processes - Choose the target application from a list of processes running on your PC. The parent file of the process is added to exclusions.

• Repeat the process to add more exclusions.
   
• Click 'OK' to register your exclusions.
