How to protect your Windows computer against the recent Petya malware attack

A new wave of ransomware attacks swept the world on Tuesday, starting with Ukraine and spreading to other regions of the world. 

Researchers already found a stupid simple way to protect Windows machines that might be affected by Petya, but that will not stop them from spreading it to other computers.

What you need to do is create a read-only file named perfcand place it in the “C:\Windows” folder on your computer. That should stop the attack, but your computer can still transmit the “disease” to others.

If your computer is running an updated Windows version, then you’re not going to contract this Petya malware. But not everybody has the latest Windows versions running on their machines, especially corporations. If activated, Petya will demand a ransom amounting to $300 in Bitcoin.

Petya is still very dangerous, the Singapore Computer Emergency Response Team (SingCERT) explained as the malware doesn’t only encrypt targeted files, but it also stops the computer from loading the operating system. Furthermore, it can spread to other PCs on the network.
