We told you on Wednesday that Adobe released an emergency security update for Adobe Flash, and that you should update right away. At the time, all we knew was that hackers were actively using it to attack computers around the world.
Now we've learned that hackers are using the attack to infect computers with either the Locky or Cerber ransomware. Locky is already spreading rapidly through other methods, and this just makes it worse.
If you put off installing the Adobe Flash update, you need to do that right now to protect your computer against this attack. To make sure you have the latest version, check this page.
Chrome and Microsoft Edge will install the latest version if you restart them. For other browsers, you'll need to install the Adobe Flash program manually.
You also need to have strong security software installed. This can prevent malicious programs like ransomware from installing if it slips on to your system.
