CUPERTINO, CALIF. ( TheStreet) -- Investors will be eagerly awaiting Symantec's ( SYMC) first-quarter results late Wednesday for signs of heightened competition in the security software market.

The Cupertino, Calif.-based firm, which competes with McAfee ( MFE), Microsoft ( MSFT) and ArcSight ( ARST), reports its first-quarter numbers after market close.

At least one analyst expects to see Symantec lose market share, particularly in its larger customer accounts.

"In the backdrop of a weak economy, spending on security and compliance still appears soft," wrote Katherine Egbert, an analyst at Jefferies & Company, in a note released earlier this week. "We think intense competition from McAfee on larger deals could further the top-line pressure."

Analysts surveyed by Thomson Reuters expect Symantec to post revenue of $1.49 billion and earnings of 35 cents a share.

Despite recording record revenue in fiscal 2009, Symantec saw its consumer business decline 1% year-over-year. The security specialist also missed Wall Street's fourth-quarter revenue forecast, underlining the challenges facing the software sector.

Jefferies & Company's Egbert nonetheless expects that server and storage management software will boost Symantec's first-quarter revenue, even if sales of security and compliance offerings are weak.

"Storage and server remains a bright spot for the company," she wrote, forecasting revenue of $542 million, above analysts' prediction of $538 million.

Investors will also be looking for more details on Symantec's product strategy when it releases its results. Fall typically marks the launch of new software products, and the Cupertino, Calif.-based firm is planning enhancements to its Norton products.

The company has also vowed to bring in more revenue through Software-as-a-Service (SaaS) in areas such as archiving, Web security, endpoint management, and data loss prevention.

Long-term, the company is also expected to reap the benefits of President Obama's ambitious IT agenda.

Obama recently unveiled his cyber-security master plan, which aims to make the U.S. less vulnerable to online threats. Key recommendations include appointing a cyber-security "czar," forging closer ties between the federal government and the private sector, and responding more effectively to cyber attacks.

Cyber-security has also been in the media spotlight recently thanks to the denial-of-service attack that recently hammered Web sites in the U.S. and South Korea.

Symantec and McAfee, however, will soon be confronted with a very different competitive landscape. Later this year, Microsoft will offer Security Essentials, a free consumer anti-virus product -- a major departure in a market driven by software subscriptions.

"I would imagine that there will be some sleepless nights at McAfee and Symantec because Microsoft has amazing brand recognition," Graham Cluley, senior technology consultant for U.K.-based cyber security specialist Sophos, recently told TheStreet.com. "In my mind, Microsoft coming out with free anti-virus software is very good because it cleans up more computers."

Shares of Symantec fell 0.3% to $17.15 Wednesday, while the Nasdaq fell 1%.
