W32dasm revisited

I last used this disassembler in **8* and I wish to use it to solve a problem. But computers come and go and somewhere along the line my program disappeared. Now I cannot buy a copy. Downloading brings viruses and blocked functionality.
Could any member help me by passing on a legitimate copy of the software, he (or she) no longer needs. Or point me in the right direction to download a clean, full version .
I am rapidly approaching my 87th birthday, still enjoying computing, but wary of taking on unfamiliar software.
Please help me if you can.

I wonder if WinDbg would help? It's offered by Microsoft. Not exactly a disassembler though.

I would personally also be comfortable installing OllyDbg for example.
