Use your computer skills and earn enough to retire. Microsoft is offering $250,000 to find the person behind the Downadup/Conficker virus. Released in October, millions of Windows computers have been affected. The Conficker worm can infect computers or hide in USB flash drives. Downadup, as we previously told you to watch out for, can turn your PC into a botnet. The reward has been offered because the company views the virus as a criminal attack, so go out there and catch the bad guys.
