This morning, security vendor McAfee announced a new online security service designed to go head-to-head with Microsoft's Windows Live OneCare. McAfee's new online service, code-named Falcon, will debut this summer and include next-generation antivirus, antispyware, and preventative "threat watch" technologies delievered automatically to your desktop via online subscription. The McAfee service does not, however, include the diagnostic and recovery services found in the Microsoft service. McAfee joins Symantec, which previously announced its own online service, code-named Genesis, in offering a brand-name alternative to Microsoft's first major foray into the security software market space. Other security vendors are expected to announced their own online services shortly.
