Powered by four anti-malware engines, MetaDefender™ for Secure Access (MD4SA) enables fast multi-scanning of endpoints for key loggers, viruses and other malware. Available as either a cloud service or software package, MD4SA is ideal for quickly scanning endpoints prior to a network, web or server login.
You can see MD4SA implemented as a cloud service on your own personal computer by downloading the MD4SA demo, Malware Scanner, which is a free tool built from the MD4SA toolkit, using the links below. You can also download the release candidate software package by requesting an evaluation.

MD4SA quickly hashes the memory of the endpoint and scans it using several remotely installed antivirus engines. MD4SA does not replace an active antivirus application on an endpoint system, but network security is enhanced by using multi-scanning technology to ensure that active processes are checked before admittance is granted through the SSL VPN or NAC gateway.

Click on the links above to download Malware Scanner, which is a free utility built using the MD4SA toolkit.
If you are looking for a solution that is more adaptable to other malware scanning needs such as file upload servers, please take a look at Metascan, our multiple engine malware scanning SDK.
