Have I got a virus in my System folder?

[YarManYak]

Hi guys,
I had a feeling I might have a virus on my PC and came across some files/folders I couldn't find much info on online. These are;

C:\Program Files (x86)\Common Files\System\ado
which has an en-US folder with msader15.dll inside plus lots of msader.dll files with two ado files.

&

C:\Program Files (x86)\Common Files\System\msadc\en-US
with lots of msad<cer/cor/dsr>.dll.mui files.

Are these suspicious? Should I delete them?

Hello... Those files and folders are on my Windows 7 OS... and the created date matches the OS clean install date I did... you should be fine... Unless your seeing constant activity and NEWER/current date OR modified/changes to these original file... As I'm not seeing this with my installed files.
