Try to dig into Sygate firewall and see why they blocked those 2 files. What was the blocking reason?
svchost.exe is the devil as said before, and I hate it too, maybe the sygate blocked it as it saw that it's a security threat
On my PC, svchost.exe, the Local Service keeps eating up memory until I close it manualy. After it re-loads automatically of course, it stands still and it's memory usage becomes stable.
It's weird that sygate blocked kernel, as kernel is famous to firewalls.
Don't uninstall the Sygate Firewall, it's one of the best firewalls I have ever used, really great and FREE too.
Thanks,
