Windows 7 system CPU bogged by windows services, no explanation
- by Alex
I'm looking at a laptop for a colleague which is running terribly slow.
A quick look showed that the CPU was 100% used by 2-3 SVCHost processes, which off course doesn't tell much since those are just 'cover' processes with services running underneath them. So I fired up process explorer in hopes of finding a shady rogue service which was bogging the system, but to my suprise I found genuine MS Windows processes (or at least damn-good disguised ones) are bogging down the system:
dnscache (DNS Client)
IKEEXT (IKE and AuthIP IPSec Keyring modules)
iphlpsvc (IP Helper)
Seen separately, these processes might seem odd to be using a lot of CPU, but taking a step back one can conclude that all three services are quite closely related to networking.
I've tried running:
netsh int ip reset log.txt
which has helped me save bizarre network-related problems in the past, but this didn't help
Off course I though about a virus, but both MS Security Essentials as well as malwarebytes (let both run a full scan).
