Update all operating system software and install all new patches, delete all emails from untrusted sources, avoiding dubious websites and downloads, and backups of important data on a regular basis are key steps.
Beware of emails, websites and apps : The most common ways for the software to be installed on a victim’s device is through phishing emails, malicious adverts on websites, and questionable apps and programs.
Your best defence in such instances is the following rule: when in doubt, don’t visit, and don’t click.
Only install software and apps downloaded from official websites, services or online stores.
Install antivirus : Make use of your antivirus software’s ransomware removal tool, it enables you to remove viruses and malware quickly and painlessly. Secondly, it actively monitors your computer and blocks all threats, while quarantining or deleting all questionable software.
Always install updates : Keep your operating system and other software updated. Security experts advise to install the Microsoft fix—MS17-010—right away. Following the installation, make sure to reboot the system.
Companies often release software updates to fix vulnerabilities that can be exploited to install ransomware.
Backup : Create secure backups of important data on a regular basis in a completely separate system. Cloud storage is another option to use, but it makes your data vulnerable to all other kinds of attacks.
Don’t pay ransom : Paying ransomware does not guarantee its removal from your computer or the safe return of your files. Plus there is no guarantee that the attackers won’t strike you again or demand more.
