Asyncio python clamav client library

Usage Examples

Ping

pvs = await PyvalveNetwork()
response = await pvs.ping()

ClamAv will respond with "PONG"

Scanning

pvs = await PyvalveNetwork()
response = await pvs.scan(path)

Stream Scanning

from io import BytesIO
from aiofile import AIOFile

buffer = BytesIO()
async with AIOFile('some/file', 'r') as file_pointer:
    line = await file_pointer.read_bytes()
    buffer.write(line)
    buffer.seek(0)
response = await pvs.instream(buffer)
