Another ransomware called “Petya” is attack and spreading afterWannaCry attack. But this “Petya” looks like the program’s creators had no intention of restoring the machines at all. In fact, a new analysis reveals they couldn’t; the virus was designed to wipe computers outright.
How to know your PC is affected?
You will see screen like this. Which mean that your PC is affected. When a computer is infected, the ransomware encrypts important documents and files and then demands a ransom, typically in Bitcoin, for a digital key needed to unlock the files. If victims don’t have a recent back-up of the files they must either pay the ransom or face losing all of their files.
