Although a virus CAN write to (and corrupt) a PC's CMOS memory, it can NOT "hide" there. The CMOS memory used for system information (and backed up by battery power) is not "addressable," and requires Input/Output ("I/O") instructions to be usable. Data stored there are not loaded from there and executed, so virus code written to CMOS memory would still need to infect an executable program in order to load and execute whatever it wrote. A virus could use CMOS memory to store part of its code, and some tamper with the CMOS Setup's values. However, executable code stored there must first be first moved to DOS memory in order to be executed

No, a virus cannot reside in the CMOS. A virus can corrupt the data stored in the CMOS, and there are many programs which can verify if this data has been altered from a stored copy. Yes, one can use a program to replace the CMOS data with the original data.
