BTW, you can upload any suspicious file to VirusTotal:
http://www.virustotal.com/en/indexx.html
Your file will be scanned by ~40 different antivirus software.
Here is the scan report for my copy of wdidle3:

Note that wdidle3.exe has been compressed with UPX:

Before submitting it to VirusTotal, I unpacked it.
