Software security vendor McAfee laid off about 250 workers, roughly 3% of its workforce, to refocus on core businesses and bolster itself to take on rival Symantec.

The affected workers were not part of the core focus in the coming year, according to McAfee.

McAfee spokesman Ian Bain was quoted by Reuters as saying that in order to better prepare the company for growth in 2012, they have made the difficult decision to reduce a small percentage of their global workforce.

Since its acquisition by Intel over a year ago, the security company has been initiating quite a few changes. But, it has seen its CEO Dave DeWalt quit this year and its worldwide CTO George Kurtz more recently.

According to Intel, the integration and assimilation of McAfee has been smooth and it had posted positive sales in the third quarter.

According to an IDC report released early this year, the top five security vendors, including McAfee and Symantec, have collectively lost 16% of their market share over the last five years.
