Serious UpLoading through scvhost.exe

I noticed a thread back in June where someoen had a problem with downloading through scvhost.exe. My problem is Uploading whan I am on the net.
There can be as many as 80-100 open ports all connected through scvhost.exe and as "HOST" names. I have loaded all makes of Spyware/Malware programmes and all come up with nothing. So I can only presume if a virus then it is hiding behind the host file. I removed Norton as it seemed to have a link to this and then loaded Kaspersky. Still the same. As much as 1.6Gb are being uploaded on a 12 hour cylcle. It does not seem to slow my computer down as the uploading speed is low.
The last thread spoke about removing BITS. Does anyone have any advice.

It's worth trying to find out what it's uploading, I think, as that could help narrow down the culprit.

If you could do this...

1. Open Resource Monitor (type-search for it in Start menu)
2. Go to the Network tab. This lists all processes using networking features.
3. Tick any svchost.exe entires in the top window.
4. Have a look through the lower windows to see if there's anything in there that could help, such as local/remote IP addresses.

It sounds like you may have already had a look at this, or at least something similar, but if not, do so :)
