Which of the following are indications that a virus has possibly infected the computer?

Question

choose all that apply.

A CMOS checksum error
B Insufficient space on drive D: error
C CMOS memory size mismatch error
D GUI image failure error

Answer 1

The answer is all four. A,B,C, or D could indicate rogue behavior, but the most likely is D. I have seen CMOS hacked, but not commonly so A is not the most likely. Insufficient space on D: would usually indicate that someone is trying to save a file to a Read Only CD ROM (typically D: is the first removable disk), but this could indicate other issues - and particularly if D: is not a read-only disc. CMOS memory size mismatch is usually caused by memory failure, adding or removing memory, or hiccups in the OS, although it could be done by a virus. GUI images not opening properly are usually a browser error, and are often the result of virus or malware. So I would say that D. is the best answer for the question
