"One computer and main server has been affected by the virus," IG Manoj Abraham, Nodal officer, Cyberdome told PTI.
As per the warning on the affected computer screen, the files have been encrypted and if it is to be retrieved, ransom in the form of bitcoin has to be remitted, he said.
It is suspected that the cyber attack has come from overseas.
Cyber police, which has begun investigations, said the attack was not serious as bank transactions had not been hit.
In a 'ransomware' cyber attack in June this year, six computers of the Southern Railway office here had been hit by the 'WannaCry' virus but there was no data loss.
