Haven't done much gaming lately. The client is set to auto-update. There were hundreds of flags from immunet after a boot up that steam was identified as w32.map.ransomware.rwd

Steam.exe

Using Immunet (abbreviated herein as "I-net"), I checked the Steam.exe* file that you attached to your post #1. I-net reported that file as clean.

I then downloaded the Steam installer from HERE and installed Steam on my Virtual Machine. After installation, I checked the newly-installed Steam.exe file. Its SHA256* is identical to your file's SHA256.  I-net also reported that newly-installed Steam.exe file as clean (to be expected, because it is identical to your Steam.exe file). I then had I-net check the entire Steam file folder (lots of files in that folder). I-net said the folder's entire contents are clean. I then started Steam, registered an account, and loaded a free game. I-net never made a peep.

On my computer, for one, the Steam folder and the file, Steam.exe, check as clean according to Immunet. Of course, my Steam folder does not contain the same settings & game histories that your folder contains. If Immunet continues to flag Steam, you may need to do a right-click Immunet scan of individual files in your Steam folder.

*Steam.exe's  SHA256: 0BDA997391C06BCE6B70DB30808136427C83F972D6D48C3554C2A042EFF09224

There have been other users reporting conflicts with the Steam gaming software & Immunet. That's why it's recommended to create a custom Exclusion rule for Steam's entire Program Files folder. That should eliminate any further False Positives.
