Using Vista Ultimate 64:
A month ago I started to notice that when I went to bed at night on a Monday night the computer was fine and connected to the internet. When I got up Tuesday morning the first thing that I noticed was that the CPU usage, via the CPU usage gadget on the desktop, 4 core, was running up and down between 27% and 59%. While running it would allow me to do vitually nothing. The next thing I noticed was that I was disconnected from the WAN & Lan and it would not allow me to neither connect or troubleshoot. In order to get my computer back I had to do a restart.
Two weeks ago the problem changed from a Tuesday morning to Saturday morning but the identical scenerio.
What I was able to identify is that the problem is from, via services, "Svchost.exe", of which there are 15 of them running. The indivdual services showed: WSCSVC; IMHosts; Event Log; DHCP; AudioSRV:
In order to retake control I had to do the restart but this time when it restarted it showed that I was connected to an unidentified network. Reset the modem/router and all was fine.
This Saturday morning, same thing with the with the cpu usage meter and internet connection dropped. Under Services it was showing AVgaurd.exe 32 - Antivirus on Access Service and the svchost.exe - System host Process for windows service; when I open subprocess services it is showing 11 of them: wudfsvc; wdi system host; Ursms; PCA Svc; Netman; Irman; IPBus Enum; hidserv; EMDmgmt; AudioEndPointBuilder; Thes are showing "Local System Network Restricted" next to them all the while when "Running"
, evan after a restart these are still running so I am presuming that they are legit.I admit by some of the names of the services it looks like a rootkit or zombie programs but everything that I throw at the C drive comes back negative including Eset and Fsecure. I have no services scheduled to run at this time of the day. This time a restart brought everything up fine.
Are these legit MS OS programs; Don't know that is why I am asking as to which direction to go.
While my computer is showing disconnect from the network the router light is still blinking indicating activaty. Daughters computer running XP and running thru the same router/modem is fine.
Any help will be appreciated and can do one step at a time in order to elimanate or identify the problem.
