Could 32-bit Windows viruses run on a 64-bit version of Windows?

Yes, all 64-bit Windows desktop OSs come with WOW (Windows On Windows).

This allows the execution of 32-bit processes on a 64-bit OS.

 

What will not work is if the malware install drivers. Kernel code needs to be 64-bit for 64-bit Windows.

If you send me messages, per Bleeping Computer's Forum policy, I will not engage in a conversation, but try to answer your question in the relevant forum post. If you don't want this, don't send me messages.

Are you having any malware related issues or just asking the question out of curiosity?
