are you guys crazy ,this is not true.there is not any feature like this in srilankan ATMs.
believe me im working at a bank that one of main banks in srilanka
from command promt goto the c:/ promt
and then type "attrib -r -s -h" and then type "del autorun.inf"
reboot the machine it will be solved.do this to all partitions.
c:/attrib -r -s -h
c:/del autorun.inf
