How do I root out what can be causing this? Because if this happens during a game I'm truly ****ed sometimes being forced to exit via task manager

Just used Hijackthis but I don't know what to make of the log...

Svchost is just a service to launch DLL files (Services). To find out which service is running under the svchost process you can use microsoft's process explorer of SysInternals.

Check if the file is located under "system 32" folder in windows if it's not it's most likely a trojan.

How do I do this?

I have a couple of svchost running sometimes, but sometimes one of them goes to 1GB usage which destroys my computer

Right click on the file in the task manager and open file location if it's not located in system 32 it's almost a trojan for sure.

Read this it will help you: Link

Svchost stands for Service Host. It is a shell process that runs one of the Windows Services.

To find out what your running services are and how much resources they are taking, copy/paste the following into notepad and save it as ServiceQuery.ps1

Link

Once saved, locate that file, right click it, and select "Run with Powershell".

Once you have identified which service is taking up the memory, you should take steps to identify why it's doing and how to remediate. A word of caution: it is considered extremely bad practice to terminate a service without investigation. You don't know what it does, and how terminating it will adversely affect your computer.

svchost is not a trojan. I have it, you most likely have it, even Caliber and 0x90 have it. If it's spiking up to 1 GB memory use there is some other program trying to launch or use a .DLL or multiple .DLL's and isn't having much in terms of success. I figure the best thing to do is keep restarting your computer until it goes back down to safe levels. Currently, my largest use of memory for an svchost process (I have more than one showing up on my TaskManager) is about 327 Megabytes of RAM, out of my total 16000 Megabytes. It's a third of the range the threadstarter said his was at.

C+A+D Task Manager
Performance Tab
Press Resource Monitor button at bottom of performance window
Look at CPU list, sort by name so you can see the svchosts and see which side system it is running.

My guess it will be the LocalSystemNetworkRestricted that is spiking.


EDIT:

One hint I will give if you are running 7 or higher, and only have 2GB-4GB RAM, turn off Superfetch.

You can do this via Start Menu > msconfig and run that

Look at the service tab and look for superfetch and disable it.

Superfetch is handy with high amounts of RAM as it will fetch any services or programs you use continually and pre-load them which helps load up apps/games etc faster. Pain in the nut sack when you have low memory, recommended for 8GB+ users.
