SYMANTEC CORP. $19 (Nasdaq symbol SYMC; Aggressive Growth Portfolio, Manufacturing & Industry sector; Shares outstanding: 652.2 million; Market cap: $12.4 billion; Priceto- sales ratio: 2.0; Dividend yield: 1.6%; TSINetwork Rating: Average; www.symantec.com) has launched a new service that aims to improve the security of Internet websites. Called “Encryption Everywhere,” this software makes it easier for web hosting firms to embed encryption when they create new websites. This will help protect users from cybercriminals and online intruders. Symantec is giving away this software for free. It feels this approach will encourage hosting firms to adopt the technology and eventually buy more security services and software. Just 3% of the world’s websites use encryption technology, so there’s plenty of room to grow. Symantec is a buy.
