Scottish health secretary Shona Robison has confirmed that there has been no further reported problems with the NHS systems following a global cyber attack.
Thirteen boards were affected on Friday but measures were put in place to isolate the systems.
The boards affected are: NHS Borders, NHS Dumfries and Galloway, NHS Fife, NHS Forth Valley, NHS Lanarkshire, NHS Greater Glasgow and Clyde, NHS Tayside, NHS Western Isles, NHS Highlands, NHS Grampian, NHS Ayrshire and Arran, NHS National Services and Scottish Ambulance Service
In many areas, with the exception of NHS Lanarkshire, the number of PCs or systems affected is in single figures.
There is no evidence that suggests patient data has been accessed during the attack.
Detective Superintendent Willie Cravens said, “We are working closely with the National Cyber Security Centre and the National Crime Agency to support the investigation.”
The First Minister and Ms Robison have been updated on the situation and Justice Secretary Michael Matheson has participated in the UK Government COBR meeting chaired by the Home Secretary this afternoon.
Ms Robison said: “This has been a global cyber-attack which has impacted on countries across the world and clearly any incident of this nature is hugely concerning – but it’s important to stress that there is no evidence to suggest patient data has been compromised.
“This week’s incident emphasises the importance for all of us – the public and private sectors as well as the general public – to have the appropriate measures in place to protect against these kinds of attack.
“We have taken all necessary steps to ensure the cause and nature of this attack is identified and have managed to isolate the issues within the NHS in Scotland.
“Boards are currently working on protecting and restoring those systems where possible, with a view to getting most operational by Monday.”
