There is apparently a current virus threat.
Something to do with the FBI no longer providing protection against a virus created by cyber crooks.
There is a link that can used to check whether your computer is at risk, although when I checked this morning it indicated that that assurance wasn't completely fool proof.
I'm posting this on my phone so can't provide a link, but the link can be accessed by going to the channel 7 SUNRISE website.
I think the protection offered by the overseas authorities ceases around 1:30pm (SA time), so anyone wanting to check this, only has a few hours to do so.
Those on here who are more IT savvy than me may have some better and clearer information.
