Computer users in Vietnam lost nearly VND8 trillion (US$378.42 million) to viruses over the past 12 months, Thoi bao Kinh te Sai Gon (Saigon Economic Times) reported Tuesday, citing a study done by Internet security firm Bkav.
It was a "very big loss," even though it was much lower than those in developed countries like the UK, where computer viruses are estimated to cause losses of $43 billion a year, Bkav said in its latest study.
The company did the study in April and compiled the figures based on the average income of computer users and how long their work was disrupted by viruses infecting their computers, the news report said.
The Bkav study also found that computers in Vietnam showed a growing tendency to get infected through USB flash drives carrying malicious codes, with 93 percent of respondents saying their USBs were infected at least once over the past 12 months, a year-on-year increase of five percent.
The risk of computers getting infected with viruses through USB drives will continue to increase in Vietnam, with the presence of W32.UsbFakeDrive, a virus detected by Bkav's systems in late March, the study said.
The virus is highly infectious and can activate automatically as soon as the users open the infected drive, the company said.
This May alone, 2,638 new computer viruses appeared in Vietnam and affected over 4.2 million computers, according to Bkav. Also last month, 425 websites of state agencies and enterprises were attacked, mostly by foreign hackers, it said .
