Microsoft participation in virustotal

The Microsoft Anti-Malware Engineering Team reports on their blog that they will be participating in virustotal.
For those that don’t know, is a way cool website where you can scan a suspicious file against around 10 vendors. This might help you see what wacky name of the week one particular vendor is using for a virus. Also it might show you who doesn’t have detection available. That’s why a few AV vendors have declined to participate in virustotal. So I think its pretty cool that Microsoft is getting involved.
