Free anti-malware software is not hard to find: even reputable vendors offer product at the low, low, price of $0.00 for client devices/
Microsoft is now doing the same for servers – or at least for virtual machines in its Azure cloud with a new offering called (deep breath now)
Microsoft Antimalware for Azure Cloud Services and Virtual Machines.
There's nothing startling about the product, which Microsoft
says can “identify, block and remove malicious software” and “provides real time protection from the latest threats, can perform on-demand scanning, and monitoring at no additional charge to Microsoft Azure customers.” Microsoft also looks to be taking the product seriously, as its log files are consumable by HDInsight or another security information and event management product. That's if you choose to have the event logs stored in Azure storage, which does come at a cost.
