A new global survey has found 78 percent of software installed on personal computers in Vietnam last year were not licensed, a drop from 81 percent in 2013.
The commercial value of the pirated software units was estimated at US$598 million, compared to $620 million two years before, according to the findings released by the Business Software Alliance on Wednesday.
The decline is partly thanks to the government's efforts to enforce anti-piracy laws and increase public awareness, said the organization, whose members include technology giants such as Apple and Microsoft.
Compared to other surveyed countries in Southeast Asia, Vietnam had the second highest software piracy rate, after Indonesia with 84 percent.
Thailand and the Philippines took the third and fourth positions with 69 and 67 percent, while the rates in Malaysia and Singapore were 53 and 30 percent, respectively.
Globally, the rate was 39 percent, down from 43 percent in 2013, according to the survey.
