CloudAV

Developed at the University of Michigan, CloudAV uses the following components to produce a high-quality anti-virus system in the cloud:

• A cross-platform host agent
• Two behavioral detection engines (resource heavy)
• A network service with 10 anti-virus engines

CloudAV uses a technique known as N-version protection, which uses multiple versions of the same anti-virus detection engines to identify malicious software. This protection mechanism scans received files before they are opened by a user.
