Detectives involved in child porn crackdown Operation Ore raided 100 addresses over the weekend, seizing 90 computers.
Surrey Police have already arrested 33 people under Operation Ore
Surrey Police said 250 officers, including child protection and data recovery specialists, were involved in the raids.
They also confiscated at least 2,000 related items, including CD-roms, floppy disks and video tapes.
A police spokeswoman said on Tuesday no arrests had been made, but they could follow after examination of the evidence.
She said: "The operation was intended to both protect children and to gather, and prevent the destruction of, evidence that will now be examined to determine if any charges should be made."
High risk individuals arrested
Surrey Police have arrested 33 people in previous Operation Ore raids across the county.
Of the 33 arrested, seven have been charged, two of those convicted and one person cautioned.
The safety of children in Surrey must be our priority
The others are on bail to appear before Guildford Magistrates on 25 April.
Police said anyone charged following the latest raids would be likely to be in court the same day.
Detective Chief Inspector Brian Russell, leading the team investigating the cases, said: "We have now arrested all those high risk individuals who we believe posed the greatest threat to young people in Surrey.
'People should be reassured'
"Following this weekend's successful visits we will be able to make further risk assessments in respect of individuals appearing on the list.
"We have now virtually completed the Operation Ore list in Surrey although some follow-up inquiries remain where, for example, people have changed addresses.
"The people of Surrey should be reassured that inquiries into paedophile activity will always be thorough and as prompt as is practicable.
"The costs are substantial but we will find the funds and we are firmly of the view that the only way to deal with long lists of possible offenders is to work with our partner agencies and prioritise those who pose the greatest risk.
"The safety of children in Surrey must be our priority."
