Ransomware attacks 2017 :- 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.

If you don’t already have a backup routine, start now and regularly save copies of all your files. That way if your machine gets infected and your photos and documents are encrypted, you don’t need to worry about losing them.

This attack has impacted many large services and organizations, including hospitals in England, a telecom and natural gas company in Spain, and FedEx. Basic services that impact your life could be impacted even if your own machine is clean.
