Software maker Symantec is recouping some of its losses from last week, trading more than 10 percent up Monday.

The company shed 33 percent and roughly $6 billion in shareholder value Friday after announcing an internal audit that could delay the company’s annual report and hurt financials in the coming quarters.

The company behind Norton anti-virus software said Monday it will host a call with investors after the bell to address the audit and its financial outlook.

Shares opened at $21.16 Monday, after closing below $20 Friday in the stock’s worst trading day since 2001.
