Windows 7: Mysterious SVCHOST activity since 25-5-2012

Phenomenon than meets the other day, and to launch the PC, higher CPU load. From Task Manager, we are using the CPU in the svchost * 32,
If you look at the process Exploer
"C:\Windows\System32\svchost.exe" -g no -t 3 -o http://great-0portunity.com:8344/ -u ivtcfliha -p doqhlr"
It seems that the command is executed, the service could not be identified.
Dropping this process, the load will fall, it will stand up to hand on a regular basis.
Did not catch the virus even if the search.
Please tell me if there is a workaround.

Not sure if these will help, but take a look

I found the way myself after doing some readings online. Thanks for the one would introduced me Combo Fix. I does fix my prob. It seems it is a rootkit. Now there is no high CPU load. I think the Combo Fix does repairs other types or vernurability as well. Please dont panic during the Combo Fix repairing session. It looks like old DOS GUI appears and command line running in it. BE PATIENT until it repairs and restarts your PC. You can trust this Application. Here is the link

Do not use Combofix on your own.
