Scanning modes

There are two scanning modes:

• By users — the system will check domain directories for viruses and domain reputation for blacklist statuses.
• By domains — the system will check user directories including all domains. Domain reputation is not checked.

To change the mode click By user or By domains. 

Scanning

To start the scanning process, click the following buttons:

• Scan all — scan all domains/users;
• Scan — scan the selected domain/user only. 

If the system detects malware objects, the infected domain/user will be marked as "infected". You will see the following buttons on the toolbar:

• Report — view the detailed report to see detected files;
• Cleanup— cure the files according to the scanning settings.

Once completed, the status in the list of domains/users will change into "Cured". You will show the number of cured threads, date and time when the clean processes started. Clicking the "Undo" button will restore the files back. 

Copies of the files before they were cured are stored in the temporary directory usr/local/mgr5/var/raisp_data/backups/.

ImunifyAV  logs are stored in /usr/local/mgr5/var/raisp_data/log. /usr/local/mgr5/var/raisp_data/log.
