What is ransomware?

Ransomware is a malware designed to deny a user or organization access to files on their computer. Once your files are encrypted by ransomware, you may have no choice but pay the ransom to retrieve your files. One of the most famous examples of ransomware is the WannaCry ransomware attack. It requested users pay $300 worth of bitcoin payments to restore their files. How frustrating it is!

How to block ransomware (3 useful ways)

If your computer is in an unsafe environment, it may be attacked easily. Thus, the best ransomware protection is to improve computer security, which can block ransomware validity. Here are the top 3 methods for you to secure your Windows computer.

1. Install patches and keep your operating system and software up to date.

This habit can prevent compromises on exploit kits. The EternalBlue exploits vulnerability MS17-010 in Microsoft’s implementation of SMB protocol. However, Microsoft released a critical advisory along with a security patch to fix the vulnerability on 14 March 2017. Organizations can apply the patch to fix the issue.

2. Turn on Windows firewall.

Windows firewall is a security system that provides a technology for separating intranet from public. It can minimize network hackers' access to your network. In the Advanced settings, you can block port 445, 139 and so on to protect against WannaCry Ransomware attacks.

3. Secure your online browsing.

Browsers are the most exposed and information-rich. It is the window to the internet and also the first line of defense against ransomware. To prevent ransomware, you must secure your online browsing. (PS: Different browsers have different ways to set up for security.)
