I had the exact same AV hit as OP, Trojan:Win32/Spallowz.A!plock http://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?name=Trojan%3aWin32%2fSpallowz.A!plock&threatid=2147697481&enterprise=0#tab-link-4
Checked out VirusTotal.com from MGIMATTY's response, and unfortunately it did find another Trojan in the file, here's the trimmed results...

Not sure the link to the file scan on VirusTotal.com will work for the rest of you, but here it is if it does.

So, 2 things... Why do you guys think the Trojan:Win32/Spallowz.A!plock is a false positive? And what about the Trojan.Yakes.buad that VirusTotal.com found?
Thank you all
