An IT expert found with indecent images on several computers seized by police from his home claimed he must have been hacked.
Richard Yates, 34, whose work for a global communications firm included contracts for the Government, said he was shocked when told what was on his computers after a police raid.
Yates, of Elgin Drive, Glenrothes, denied that between June 16 2008 and December 20 2012 at his home he downloaded indecent photographs of children.
He also denied being in possession of indecent images of children and a third charge that on December 20 2012 he was in possession of extreme pornographic images depicting in a realistic way an act involving sexual activity between a person and animals.
However, he was found guilty by a unanimous verdict on all three charges.
On the final day of a sheriff and jury trial at Dunfermline Sheriff Court, Yates, a systems/network engineer, said he had worked in IT since he was 16.
Asked by his solicitor Christine Hagan what his reaction had been when police arrived at his door early in the morning, Yates said: “I thought it was a wind-up, a joke, for a few seconds.”
He said he knew nothing about the indecent images of children on his computers and had never viewed any of them.
However, depute fiscal Ronald Hay accused Yates of being a liar and said his admission he had an internet account in a false name was evidence of that.
Yates was put on the sex offenders register.
He will be sentenced on September 2.
