China issues warning over new ransomware virus

China has urged Windows users to protect themselves against a new ransomware virus similar to the WannaCry bug that wreaked havoc worldwide last week. "UIWIX" encrypts and renames files through a bug in the Windows operating system, China's National Computer Virus Emergency Response Center (CVERC) warned in a public announcement yesterday, telling users to install the latest Microsoft update.

The warning comes on the heels of the "WannaCry" cyberattack, which has hit hundreds of thousands of computers worldwide.
