Let us know if you can boot into safe mode. Right before the Windows loading screen press F8 and select "Safe mode without networking". Then run the A/V software. Safe mode will only load the most essential drivers to run. Svchost is network-related so you should select without networking...I am not positive if it loads or not anyways but that's your best first move.
