Here's how to avoid the credit crunch: Pay cash.

McAfee (MFE), a provider of computer security products and services, agreed to buy Secure Computing (SCUR) for $5.75 per share in cash, or about $413 million. The deal also calls for Secure Computing's preferred shares to be redeemed for cash, adding about $84 million to the deal.

The deal is expected to close in the fourth quarter.

McAfee says the acquisition will improve its position in security risk management, a key sector as companies conduct more business online.

Dave DeWalt, CEO and president of McAfee, said: 

"We expect the pending combination of McAfee and Secure Computing will create an annual projected combined revenue of just under $500 million in the network security segment of our Security Risk Management portfolio... and will allow us to immediately establish a leading and highly competitive position in the network security space."

McAfee develops security products to protect computers, networks and mobile devices. Other products include data loss prevention, mobile security, host intrusion, prevention, e-mail security and encryption. In addition, McAfee offers consulting and training services.

McAfee continues to take a bite out of Microsoft's (MSFT) efforts to expand beyond desktop computers. Other competitors include Symantec (SYMC) and Trend Micro, a Japanese company.
