Iqvw64e.sys identified as a threat

I have used NPE a few times and often it flags up iqvw64e.sys as a threat.  Sometimes it successfully removes this and other times fails.  I am obviously concerned from what I have read that there really is a piece of malware hiding in this file.  On the NPE report it has no details on the file.  I have searched the c drive for the file and found it in 3 places:

c:\ProgramFiles\Dell\SupportAssistAgent\PCDr\SupportAssist\6.0.6992.1236

c:\ProgramFiles\Dell\SupportAssist

c:\Apps\334CH\includes\aa\internal

I used VirusTotal to scan each which reports them as clean.  I an not hugely IT literate so would value any feedback about how reliable these results might be.
