I wager that the person asking this question is not an expert in this field and has been exposed to a lot of misinformation which leads them to falsely believe that they know something about computer viruses.
Let me first say that Win32 malware by definition is not a virus. No, win32 malware can’t infect other computers or get passed from computer to computer as easily as viruses are capable of doing.
A “Win32 malware” also cannot function completely autonomously on your system like many viruses do. They need you (the victim) to be operating your infected computer for the infection process to work properly – so no, vast majority of infections happen because some mindless user wanted something specific out of it and then got tricked into installing a piece of software that has malicious code or what usually called a “malware” inside it.
In short, win32 malware is not a virus. It might have some qualities that resemble those of a virus but as I’ve stated above – those are only accidental similarities and they do not define any one infection as being a member of the larger virus family.
