McAfee has released a beta version of its next-generation antivirus software, code-named Falcon.The beta release comes just weeks after McAfee unveiled the product suite, which it is billing as an alternative to Microsoft\u2019s Windows Live OneCare and Symantec\u2019s upcoming Norton 360. The software can be downloaded here.With Falcon, McAfee has redesigned two of its existing products\u2014VirusScan and Internet Security Suite\u2014and is introducing two offerings: PC Protection Plus and Total Protection. The products, which are expected to ship by September, all include a new user interface as well as the SiteAdvisor website-rating software that McAfee acquired earlier this year.On Friday, the security vendor released beta code for two of these four suites: VirusScan Plus\u2014the entry-level consumer product\u2014and Total Protection, its most feature-rich security software.With OneCare now on retail shelves, traditional antivirus companies like McAfee are scrambling to come up with products that will keep them one step ahead of their new competitor. Microsoft has shaken things up in the consumer security space by throwing PC tuning and backup software into OneCare and by including three user licenses with each copy sold.Like OneCare, McAfee Total Protection includes backup and restore, as well as the tuning capabilities. VirusScan Plus does not perform backup and restore, but PC Protection Plus is being designed for VirusScan users who want a basic security product with that feature.The fourth Falcon product, an updated version of McAfee\u2019s Internet Security Suite, will have all of the advanced features of Total Protection, save one: a wireless security capability.These products will range in price from US$39.99 for the entry-level McAfee VirusScan Plus product, up to $99 for a multiuser version of McAfee Total Protection. Like Microsoft, McAfee also plans to offer a single license for up to three users, a configuration that is designed to simplify home office license management.McAfee has no plans to release beta versions of PC Protection Plus and Internet Security Suite, the company said Friday.-Robert McMillan, IDG News Service (San Francisco Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
