Question

QUESTION 3. One day you received a report of a suspicious program. By taking a glance at the following code segment, even though you are not so familiar with the assembly language, you immediately realized that this could be a ___(type) virus program since ___(reason). Codes in ___(lines) could be used as its virus signature.

mov eax, 5
push ecx
pop ecx
add eax, ebx
swap eax, ebx
swap ebx, eax
call [eax]
nop

I feel it's the last line "no operation", though I'm uncertain of the type, applicaiton, and signature. Any help is appreciated! Please do not use an answer from Chegg as their only answer was unhelpful.
