Prevent WannaCry from infecting your computer system


WannaCry, also known as Ransomware is a Trojan horse virus that has caused world-wide panic by infecting almost 200,000 computers in more than 150 countries. A British hacker had slowed the pace with which it was spreading by locating what is called as the kill switch. However, the kill switch was removed making it almost unstoppable and Ransomware continues to wreak havoc on computer systems worldwide.

Hackers responsible for creating WannaCry usually demand a pay of $300 to $600. If there is failure in timely payment then the hacked files are deleted permanently. This has caused widespread panic among businesses and individuals as well.

However, apart from patch and information from the IT guys in every country; there are some basic steps that can be undertaken to keep your system safe from Ransomware attacks.

1) Do not run unknown files

A majority of Trojan horse viruses like WannaCry can spread when a user downloads a file from an unknown vendor. Usually, files sent as e-mail attachments from obscure URL’s are in fact malware and virus programs. It is highly advised that you not open any mail or file received from an unknown source. However, some Windows OS’s including Vista have a feature named User Account Control that can help prevent Ransomware from having full access to the system.

2) Data Back-up

Despite regular back-up and updates, there is a chance that your system might be compromised. If your system has some sensitive data especially if you own a business; you should always have a back-up of the entire data. This data back-up can be taken on either an external hard drive or online cloud service.

3) Automatic updates
