World catches computer virus

When a virus ( 病毒) comes into our body, we get sick. The same thing can also happen to a computer. Avirus may destroy (破坏) the software (软件) and make it stop working.

Since May 12，a computer virus, WannaCry, has infected (感染) computers in over 150 countries, including Russia and the United Kingdom. It has hit tens of thousands of computers in China, reported Beijing Morning Post.

Once WannaCry gets into the computer, it locks all the documents (文件) and asks for money from the user. At first, it asks for $300 (2,068yuan) to give all the documents back. If the user doesn’t send the money in 72 hours, the price goes up to $600. It will lock the document forever if the user doesn’t pay in seven days.

The WannaCry virus is the most serious one in history, according to Europol (欧盟刑警组织). Users should update (更新) the new Microsoft security patch (安全补丁) and not open unknown emails.
