Get Started
You can run it by opening executable file in the bin folder with a command as the execution argument. For example: XvirusCLI.exe interactive
.
Avaiable Commands
You have the following commands available:
- Interactive - Starts Xvirus CLI in interactive mode. When in this mode you can write commands and the executable will keep running until you call the
quit
command. - Quit - Stop Xvirus CLI execution.
- Load 'force' - Loads Xvirus Scan Engine into memory, if set
force
=true it will reload the scan engine, even if it is already loaded. - Unload - Unloads Xvirus Scan Engine from memory.
- Scan 'filepath' - Scans the file located at
filepath
. It will print one of the following messages:- "Safe" - If no malware is detected.
- "Malware" - If malware is detected but the name isn't known.
- Malware Name - If it is malware from a known family (example: "Trojan.Downloader").
- "AI.{aiScore}" - Score of the file using XvirusAI from 0 to 100, the higher the score the more probable it is malicious (example: "AI.99").
- "File not found!" - If no file is found in the submited path.
- "File too big!" - If the file size is bigger than the set limit.
- "Could not get file hash!" - There was an error calculating the hash of the file.
- ScanFolder 'folderpath' - Scans all the files inside the folder at
folderpath
. It will print the scan result message for each file scanned. - Update 'loadDBAfterUpdate' - Checks and updates the databases and AI engine to the most recent versions. If
loadDBAfterUpdate
=true then it will reload the Xvirus Scan Engine after the update is done. It can print the following messages:- "There is a new SDK version available!"
- "Database was updated!"
- "Database is up-to-date!"
- Logging 'enableLogging' - Sets and prints if
Logging
is enabled. If noenableLogging
value is provided it will only print. - BaseFolder 'baseFolder' - Sets and prints the
BaseFolder
path. If nobaseFolder
value is provided it will only print. - Settings - Prints the
settings.json
file. - Version - Prints the version of the SDK/CLI.
Settings
Settings are located in the "settings.json
" file in the root folder of the SDK/CLI. Available options:
Engine Settings
- EnableSignatures - Enables signature-based scanning of files. Default: true
- EnableHeuristics - Enables heuristics scanning of files. Default: true
- EnableAIScan - Enables XvirusAI scan engine. Default: true
Scan Levels
- HeuristicsLevel - Heuristics aggressiveness level from 1 to 5, higher is more aggressive. Default: 4
- AILevel - AI scan aggressiveness level from 1 to 100, higher is more aggressive. Default: 10
File Size Limits
- MaxScanLength - Maximum file size to be scanned in bytes. If set "null" then there is no limit. Default: null
- MaxHeuristicsPeScanLength - Maximum PE file size for heuristics scanning in bytes. If set "null" then there is no limit. Default: 20971520 (20MB)
- MaxHeuristicsOthersScanLength - Maximum non-PE file size for heuristics scanning in bytes. If set "null" then there is no limit. Default: 10485760 (10MB)
- MaxAIScanLength - Maximum file size for AI scanning in bytes. If set "null" then there is no limit. Default: 20971520 (20MB)

- DatabaseFolder - Path to the database folder, it accepts both relative and absolute paths. Default: "Database"
