Microsoft previously reported that its new Security Essentials anti-malware solution (see my review) had garnered 1.5 million downloads in its first week of availability. Well, the numbers keep going up: After two weeks, the download total stood at 2.6 million. Also, the company tells me that Microsoft Security Essentials has achieved ICSA Labs Anti-Virus Certification on Vista Ultimate 32-bit and Vista Ultimate 64-bit in the Desktop/Server AV Detection & Cleaning Testing criteria. This certification builds on its October certification from West Coast Labs.
