Microsoft released a free beta version of its AntiSpyware program in January 2005, making it available for download directly from the company's website. The software, built on technology acquired through Microsoft's recent purchase of Giant Company, aims to defend Windows computers against malicious programs that secretly collect user data or hijack web browsers.
The company also announced a separate tool, due the following week, to detect and remove viruses and harmful software from users' machines, intended to work alongside existing antivirus products rather than replace them.
The announcement sent shares of established security firms tumbling. McAfee fell more than 4 percent to $25.51, while Symantec dropped more than 6 percent to $23.48. UBS analyst Daniel Cummins noted the move highlights serious privacy vulnerabilities in Windows.
Despite the stock declines, Cummins said he expected no meaningful impact on actual sales at either company. Prudential Equity Group analyst Michael Turits maintained an overweight rating on McAfee, citing strong growth prospects in its corporate segment, which accounts for roughly 60 percent of its revenue, though he acknowledged the consumer security market would likely grow more competitive.
