The tech sector dipped Friday, as shares of McAfee Inc. plummeted a day after the security-software company posted a drop in third-quarter earnings.

The Nasdaq Composite Index (RIXF) slipped 0.6% to 2,085. The tech-heavy benchmark also was poised to close the week down more than 3%.

Leading the decline was McAfee (MFE) shares, which lost 7% after the company reported a 25% drop in profit.

"We think the street will view these results as disappointing," Deutsche Bank analyst Todd Raker said in a note. "It appears the macro has muted some of this momentum near-term, but remain encouraged that results will improve as the PC market and IT spending rebound."

Barclays Capital analyst Ben Reitzes affirmed the upbeat view of the PC space in a Friday note, saying, "checks ... still indicate rather healthy consumer PC unit demand trends in the back half of 2009."

But tech investors were taking a breather as the week drew to a close, and most major tech issues retreated. The Morgan Stanley High Tech 35 Index (MSH) fell 0.6%, while the Philadelphia Semiconductor Index (SOX) was off 1.4%.

A bright spot came from BMC Software Inc. (BMC) shares of which gained more than 2% a day after the company posted a higher quarterly profit.

Meanwhile, shares of RealNetworks Inc. (RNWK) fell more than 1%, after posting gains earlier in the session. Late Thursday, the digital media company swung to a third-quarter profit.

Shares of KLA-Tencor Corp. (KLAC) lost more than 2%. On Thursday, the semiconductor capital equipment company reported a higher quarterly profit.

Shares of chipmaker Maxim Integrated Products Inc. (MXIM) also sank more than 3% after the company reported lower quarterly profit.
