Install a protection solution
Kaspersky applications with latest databases will block the attack and prevent the malware from being installed on your computer. Latest versions of Kaspersky products feature the System Watcher component, which automatically creates backup copies of files if a suspicious program tries to access them.
Regularly back up your files to a cloud or an external drive
To protect your files from possible malware attacks and damages to your computer, create backup copies and store them in a cloud storage or a removable drive.
Install updates
Keep your operating system, software and other applications up-to-date. Updates contain fixes and improvements that make applications and the system more secure and stable. Updates are the main means for removing vulnerabilities.
If you have a Kaspersky application installed on your device, update its anti-virus databases regularly.
With obsolete databases, your Kaspersky application will not be able to timely detect new threats.
Do not open attachments in emails from unknown senders
Ransomware often spreads via infected email attachments. Cybercriminals aim to persuade you to open the attachment, which is why they title the emails as though they contained important information such as a court order, notice of intended prosecution, late fee notice or something similar. Always check the sender's address before opening emails or attachments.
Use strong passwords for Windows accounts if connecting through Remote Desktop
We recommend that you use strong passwords to protect your personal data and your accounts from being hacked during remote connection. Use the Remote Desktop feature from within your home or corporate network and try to avoid using it while connected to a public network. For more information about the remote desktop feature, see the Microsoft support website. For tips on creating a strong password, see this article.
