If we are comparing 2017 android with 2001 Windows we also need to compare the exploits. During times of 2001 windows we saw things like worms that permanent destroyed hardware (or forced owners to replace them), worms that shutdown whole city networks, computers that got infected in less than a second when connecting to the Internet, and botnets that were bigger than the biggest super computers of the time. The harm were big and scary on a global scale, and specific malware were often calculated to cause billions in damages. On the "lower" end there were bank account hijackings and credit card theft.
