What is ransomware
and how to protect yourself against it
Imagine losing all the photos, videos, messages, and documents you've stored on your computer. How much money would you be willing to pay to get it all back? Ransomware is malware that infects your computer, locks it, and demands payment for unlocking it. Here's our quick guide to ransomware — what it's all about, and five top tips on how you can prevent becoming a victim of ransomware.
5 tips: avoid becoming a victim of ransomware
Prevention is better than looking for a cure, and that's certainly true for ransomware. Here are our TOP 5 tips to keep your devices clear of ransomware:
Make sure you're running a robust security solution that covers all your devices (PCs, Macs, smartphones, and tablets) and provides protection. F-Secure SAFE protects against all the known ransomware threats that are out there, and it can block brand new zero-day threats as well. As new ransomware variants keep popping up lately, this is important.
Take regular backups of your data. Store the backups offline, so that they can't get infected. And test restoring them from time to time to make sure that they really work. With good backups, if you do get hit, you can get back on your feet faster without having to fork over cash to the criminals.
Keep the software on all your devices up to date to prevent exploits. If you are uncertain how to keep everything up-to-date, you may consider utilizing a tool that identifies old software versions and suggests updates.
Be extra careful with email attachments, especially with ZIP files and Office documents (Word, Excel, and PowerPoint). Don't open email attachments that are sent by someone you don't know. Also disable macro scripts from any Office files you receive via email.
Limit the use of browser plugins. Disable commonly exploited ones such as Flash Player and Silverlight when you're not using them. You can do this through your web browser under the plugin settings.
