2 Charged With Fraud of Millions From Pianist

In August 2004, Roger C. Davidson walked into a computer services shop on Main Street in Mount Kisco, N.Y., seeking help with his virus-plagued computer. Mr. Davidson, 58, knows music, not necessarily computers. A pianist, he is president and founder of a nonprofit sacred-music group in Katonah, N.Y., where he lives. He is also the great-grandson and the great-grandnephew of the two brothers who founded Schlumberger Ltd., the giant oilfield-services company. Mr. Davidson worried that the music he had composed and saved on the computer could be lost. The owner of the shop, Vickram Bedi, 36, confirmed that there was a virus on Mr. Davidson’s computer, a virus Mr. Bedi said was so troublesome that it had also damaged the shop’s computers, officials said.
