CyberDefender, a provider of PC security and antivirus and antispyware programs, today began trading on the Nasdaq Global Market.

The Los Angeles company, which went public on the Over-the-Counter Bulletin Board in 2007, said the listing will provide greater liquidity to its shareholders and make its stock available to a broader investor community. It received Nasdaq approval late Tuesday.

“Listing on the Nasdaq Global Market is a key step to taking our company to its next phase of growth,” said Chief Executive Gary Guseinov, who is scheduled to preside over the Nasdaq closing bell later Wednesday. “CyberDefender is the only publicly traded cyber security provider primarily focused on the direct-to-consumer market.”

The company last month reported a narrower first quarter net loss of $1.9 million, compared with a net loss of $4.8 million a year earlier. Revenue jumped 197 percent to $9.5 million.

The company’s shares, which trade under the ticker symbol “CYDE,” were up 5 cents, or 1 percent, to $4.60 in midday trading on the Nasdaq.
