The Bkav Corporation has warned that up to 1.2 million computers in Vietnam might have been infected with a destructive virus that can wipe all data on the users’ USB drive.

According to Bkav, the virus called W32.XFileUSB can create a fake drive icon or a fake shortcut to attack files on USB drives. When a computer is infected with this virus, once the user connects to his USB device, the virus will delete the files on the USB and replace them with fake files containing malware. When the virus-infected USB is inserted into another computer, the virus will continue to spread.

The virus can not only cause data loss but also take control of the computers to download more malware to spy the computers or launch a targeted attack.

Bkav estimated that computer viruses caused economic losses of up to 541.2 million USD, last year, up 18.27 percent from 457.6 million USD in 2016 and more than 41 percent higher than 2015’s figure.-VNA
