Windows 10: Unsigned .dll filed in System32 folder.

I've found two files named 'wosc.dll' and 'fcon.dll', I went in to properties and found they do not have a signature on them but they are copyright to Microsoft Corporations. I scanned for viruses and they were not deemed malicious. What are these files?

Unsigned .Dll files

I've got a reoccurring issue with my .dll files.

The issue is related to games on my PC that use EAC (Easy Anti Cheat), and every time I launch a game using EAC, I am prompted with Untrusted system file (C:\Windows\System32\a
random dll file). I thought the issue might have been related to one game, Apex. But on further attempts to fix the issue, I found that other games that use EAC were also throwing the same "untrusted
system file" error, and it's not always the same .dll file.

I have tried the generic SFC scan/repair commands but have had no luck, along with deleting/replacing dll files from system32.

Today I checked my system32 dll files by using CMD & sigcheck,
I have found that pretty much every .dll file scanned is marked Unsigned (Example shown below)

Verified: Unsigned

Link date: 2:27 PM 23/01/1917

Publisher: n/a

Company: Microsoft Corporation

Description: Unicode Normalization DLL

Product: Microsoft« Windows« Operating System

I have a support ticket opened through EAC, but their replies take days.

Any help is appreciated, here's hoping I don't need to re-install windows.

 

Unsigned files in system32

I used sigcheck to check system32 earlier today and found that several .dll and .exe files were marked as unsigned. Most of these said that they were from Microsoft in their description. I googled it and it seems like some Microsoft files just aren't signed.
Does any one know why that is?

There were also three files that didn't seem to be related to Microsoft. The first was nvinitx.dll that couldn't build a certificate chain to a trusted root authority and seemed to be from Nvidia, and a .dll as well as a .exe that were unsigned and seemed
to be from Vulkan Runtime. I checked them all with VirusTool and they seemed safe, but is there any reason for them to not have a signature in that case?

Thanks in advance,
Oliver

 

msvcp100.dll and msvcr100.dll in C:\

Hello back TPU!

Yesterday I saw two files(msvcp100.dll and msvcr100.dll) in my C:\ disk folder. What does this mean? I know this two files should be in C:\Windows or C:\Windows\System32 or somewhere in C:\Windows but not in main disk folder. I deleted this files but files appeared again today. Is this a virus or maybe an application? How can I check this?
