新电脑病毒扑面而来，Petya到底是什么？

如果你的电脑不幸被Petya加密，那么即便支付赎金也无济于事。你必须联系来获取解密密钥，而该电子邮件地址已被邮箱服务商关闭。除非新的勒索软件提供另一个电子邮件地址，否则不可能恢复你的文件。

Is there a Petya "kill switch"?

有没有Petya“自杀开关”？

No. However, there are a couple of ways that you might be able to prevent or stop the encryption process.

没有。不过倒有几种方法可以防止或中断加密过程。

First, if your computer randomly begins to shut down, abort the shutdown process and keep it running. The Petya worm has to reboot the machine in order encrypt the hard drive's Master Boot Record, which is essential to the Windows startup process.

首先，如果你的电脑突然开始关机，应立即中止关机，保持电脑开机状态。Petya蠕虫必须重启电脑才能加密硬盘驱动器的主引导记录，主引导记录对Windows启动过程至关重要。

Second, you can try to "immunize" your machine by creating a read-only file called "perfc" and putting it in the Windows directory. In some instances, if the Petya worm sees that file, it won't encrypt the machine — but it will continue to spread to other machines on the same network. However, we've seen reports that this method doesn't work on Windows 7, and that new versions of the Petya code may not have this function.
