A cyber-attack has hit 150 countries so far, including our own NHS, and it is quite a scary thought for a lot of people who are not computer-literate.
In the UK, 61 NHS organisations were affected by the virus, which forced hospitals and clinics to turn away patients.
The scam freezes your computer and demands money in order for you to be able to use your computer again.
Europol has said the attack is ‘unprecedented’, with Russia the hardest hit, although companies in France, Spain and the U.S have been badly affected by the ransomware attack.
Reports are suggesting that this attack could continue as the working week begins, with employees switching their computers on after the weekend.
The virus appears to have stopped spreading to new computers for now, but there is no reason to suspect that the hackers could simply change the code and start the process again.
The WannaCry virus is only infected Windows operating systems, so you could be at risk if you haven’t updated Windows recently.
Anti-virus software, updates and firewalls are the best way to protect yourself from the virus. Backing up your data somewhere else is also an excellent way to protect yourself.
It is quite scary to think that somebody can just block everything on your computer and demand money from you to get it back.

This attack should serve as a reminder to all of us that thieves operate in the virtual world as well as the real one. You should protect your computer and any sensitive documents as much as you would protect anything else.
