Avast Software, maker of the world's most popular computer antivirus program, will need a year to absorb its $1.3 billion buy of rival AVG but may seek further acquisitions before an expected flotation, its chief executive said in an interview, according to Reuters. From a report: Prague-based Avast closed its purchase on Friday of AVG Technologies, another software firm with Czech roots specializing in consumer security. The combined company will have over 400 million users and 40 percent of the consumer computer market outside of China. While Avast will delist AVG shares, it has its own plans to eventually offer shares, maybe as soon as 2019. Before that, it must fully integrate AVG and will then look at mid-tier acquisitions for its push into mobile and, possibly, to expand its small- and medium-sized business offering. "We have to digest AVG first and that is going to take us pretty much all of 2017 to really integrate. Then we will look at expanding the business after that," Avast CEO Vincent Steckler said.
