Kaspersky Lab's sales growth slowed in 2011 CANCUN, Mexico (Reuters) - Russia's Kaspersky Lab reported that sales growth slowed substantially last year as the world's No. 4 maker of anti-virus software said its business was starting to mature. The company, co-founded by computer security expert Eugene Kaspersky, said that sales grew 14 percent last year. That is down from growth of 38 percent in the prior year. Revenue totalled $612 million last year. The company declined to provide profit figures. Chief Sales and Marketing Officer Garry Kondakov downplayed the decline, saying that the drop was a result of the company's maturation. "I think it is natural," he said at a press briefing in Cancun, Mexico. He said that Kaspersky Lab's sales were still growing faster than the overall anti-virus market.
