Getting Error After New Update (Sophos~1.DLL)

Hello everyone, 

Today we started receiving errors on few of ours windows 7  OS Installed machines. 

The following error received

Message > C:\Windows\system32\SophosAV\SOPHOS~1.DLL\ is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

Any help would really be appreciated.
