- ClamAV detects millions of viruses, worms, Trojans and other malware, including Microsoft Office macro viruses, mobile malware and other threats.
- Signed signature databases ensure that ClamAV will only execute trusted signature definitions.
- ClamAV scans inside compressed archives, but also protects against archive bombs.
