- We know that one of our suppliers, where we have our HR system, has been hit by a ransomware attack, says Mats Möller, IT manager at the university, who takes the incident seriously.

Is there anything you could have done to avoid this?

- No, not as I see it.

Other universities that have the same system and suppliers of the operation have also been affected by the IT attack.

See how the IT attack affects the University of Karlstad in the clip above.

Some companies have also been affected.

SVT went to Granngården in Karlstad, which is closed until further notice due to technical problems in the wake of the hacker attack.

In the clip, we meet the customer Magnus Jonsson, who had to wait with his case in the store.
