Avast Software has closed its acquisition of AVG, the company announced Friday, a move CEO Vince Steckler said will allow the two traditional security software companies to better compete in today’s competitive endpoint security market.

Avast first announced the acquisition in July, saying it planned to acquire AVG for $1.3 billion. The deal brings AVG’s anti-virus, remote monitoring and management, Internet security, mobile security and cloud security offerings to Avast’s own anti-virus, mobile security, email security and file server offerings. In total, the combined companies will protect 400 million endpoints, of which 160 are mobile.
