How to protect yourself from the massive ransomware attack
Ransomware is a type of malicious software that takes over a computer and locks the user out, preventing them from accessing any files until they pay money. This particular program, called WannaCry, asks for about $300, though the price increases over time.
The worm is primarily impacting business, where it can spread quickly through a network to take down an entire company. Business take longer to install critical updates and patches, often to avoid impacting any legacy software they are running.
But individuals with PCs running Windows should still take a few precautions. First, install any software updates immediately and make it a regular habit. Turn on auto-updaters where available (Microsoft offers that option). Microsoft also recommends running its free anti-virus software for Windows.
