Upload following files to VirusTotal - Free Online Virus and Malware Scan for security check:
- explorer.exe located @ C:\Windows
- userinit.exe and svchost.exe located @ C:\Windows\System32
Post scans results.

Is this what you need?

I can see: File explorer.exe received on 2009.08.30
Did you settle for VirusTotal suggestion "this file has been already analyzed...", or you scanned your fiel anyway?

I'm not sure what you are asking. I did like you said and uploaded it. They all are showing that they have already been scanned but I don't know why. For security I'm removing the links.

When you upload popular file, like explorer.exe, you'll get this message:



Which button did you click?

I forgot which one but I'll try again.

Make sure, you press "Reanalyse..." button.

PM for you.

I got it.
