Microsoft Security Essentials, free anti-virus security software released
As promised, Microsoft just released its free security program for Windows XP/Vista/7 this week. This is anti-virus/anti-malware/anti-spyware/anti-trojan/anti-rookit software. It replaces Microsoft Defender.
The big question here is whether or not Microsoft will run products made by Symantec, McAfee, et al out of business.
