WannaCry 2.0 or WannaDecrypt0r 2.0 ransomware is turning out to be one of the biggest security threats on windows pc today. It is malicious software that encrypts computer files (hard drive) preventing the users from accessing any files until they pay money via bitcoin. This particular program, called WannaCry, asks for about $300. The price increases over time and if you are still not going to pay until the deadline, your files will be completely locked out.
Here are some ways to prevent WannaCry ransomware from attacking your windows PC.
1. Update your windows PC regularly.
The "WannaCry" ransomware appears to have used a flaw in Microsoft's software, discovered by the National Security Agency and leaked by hackers, to spread rapidly across networks locking away files. So always keep your PC updated.
2. Disable Server Message Block (SMB) on Windows Features
According to some security experts, you can prevent WannaCry ransomware attack by disabling a windows feature called SMB that has something to do with the sharing of files and printers with computers running older versions of Windows.

2. Avoid Clicking on Links or Opening Attachments from unknown emails.
A simple link can bring you to websites that are full of malware. An attachment can contain bad macro scripts especially if you are opening an office application (word, excel, etc.).
3. Do not Download or Install Untrusted Windows Applications
Do not install cracked software. Always download the application from its official website. Do not install application that you just downloaded from somewhere else.
4. Always Check the File Extension before You Click
If you are going to open a file from your download folder, be sure that it does not end with “.exe” unless you are opening an application. If you are opening a picture, make sure it ends in “.jpg, .jpeg, .png, .gif”. A real file does not have“.exe” extension.
5. Backup Your Files to External USB Storage
It is always better to have a backup. You should do it regularly especially if you are working on very important projects.
