Fears a massive computer virus could spread following ransomware attack

Businesses are on high alert this morning following fears a massive computer virus could spread to Northern Ireland.

Staff are warned to be vigilant about using their computers, after a hack affected 48 out of 248 NHS trusts.

200,000 victims in 150 countries are said to have affected in the cyberattack, which took place over the weekend.

The spread of the ransomware worm 'WannaCry' has now slowed but it's feared that a reworked version could cause further problems.

"At the moment, we are in the face of an escalating threat. The numbers are going up, I am worried about how the numbers will continue to grow when people go to work and turn (on) their machines on Monday morning,” said Head of Europol Rob Wainwright.

Users are advised not to open any suspicious emails.
