How do I remove a virus that AVG won't detect?

@ Francesco Cantalini
Francesco, Correct! That info was in my 1st posting.

I know that no antivirus can detect 100%, but most want a sample of the virus if it's not detecting it.  I thought this would be a great opportunity for that, but I can't get ahold of anyone.  I just emailed jamie@avg.com, and I'll see if I get a response.

I have a virus on a Windows 7 computer running AVG Cloudcare with the latest updates.  As soon as the computer is connected to the Internet, there are a bunch of svchost.exe processes that start connecting to hundreds of locations on the Internet and bring down the Internet connection for the entire company.  <br>
I have done several rootkit scans and full computer scans, but AVG says the computer is clean.  I downloaded malwarebytes as well, but again it doesn't find anything.  

I've tried to use Sysinternals Process Monitor to determine what is starting all the svchost instances, but I haven't had any luck with it.

I can't get ahold of cloudcare support, so I thought I would try a post here.

Any suggestions?

Thanks!

If you know where these suspicious files are, you can submit them here False Positive File Form
