Scan shows malware in Steam installation

[Noob-Tech-Ninja]

Hi there guys.

I was wondering if you could help me with an issue that I've just discovered
on my Steam installation

I run Linux as my main OS for my computer.
Occasionally I will used a USB stick with some anti-malware apps on them and scan
my Linux box for any kind of malware (Windows or Linux) or associated issues.

I have a license for Kaspersky Total Security (which I use on my Windows box)
But I also use the KRD  (Kaspersky Rescue Disk), and this is what I have used to scan my Linux box

 

I came across this hit/issue this morning, after running a scan last night -

[code]
HEUR:Trojan.Win32.Msb.a

@Filesystem[33336756-65dd-e261-038e-7d45410180e1]/[my username]/.steam/debian-installation/steamapps/common/Proton 8.0/dist/lib64/wine/x86_64-windows/mscoree.dll

Trojan program
MD5:D5A6CC9419D9ED38976A3008BA0ED790
SHA256:495CB7D12B425220BF98D9A191B0DF2FAF82DD07FF44BD32F3940CEFB077B501
[/code]

Questions:

1. Based up on the information above, should I be worried ?

2. Is this a false positive ?
(The anti-virus / malware app) doesn't appear to like this file

3. Has anyone else had the same or something similar when using Steam on their
Linux box ?

TIA for any help or advice
