    Hello,

    One of the svchost.exe process is using higher memory than usual.

    It's using 64,140K which is to much as when I end the process, the physical memory usage drops to around 900mb. It's at 1.34GB at the moment.

    I am running Windows Vista.

    Yesterday I had a virus but I removed it. I think it may be playing a role in this. I used MalwareBytes to fully scan the computer and it removed one threat which I dont think was related.

    Thanks.

    Please click here to download and install version 2.0.2 of the HijackThis Installer.

    Run it (as Administrator) and select Do a system scan and save a logfile.

    The log will be saved in Notepad. Copy and paste the log in your next post.

    Do not fix anything

    When did you remove McAfee?

    Run the McAfee Removal Tool.

    Let me know if it helps.

    And please post a fresh HijackThis log.

    Your log shows traces of Classroom Spy Pro. It's a very questionable program even identified as spyware.

    You seem to have uninstalled it but there are traces left.

    How do I remove that?

    I ran the McAfee removal tool. It says it want to restart but I thought I post the HiJack log first:

    How did you uninstall the program in the first place?

    To remove the traces I see,

    Press the Windows key + R to open a Run box.

    Type in CMD.

    In the Command Prompt, type (or paste): sc delete NLCSAgent

    Click Enter.

    McAfee is gone.

    Have you noticed any improvement so far?

    I removed McAfee the normal way - the uninstall option in the control panel.

    I also followed your cmd command.

    There hasn't been much improvement, still the same really.

    How much RAM is on that computer?

    How high is the CPU usage (%) of that svchost.exe process?

    Each svchost.exe process is composed of a number of Services. You'll need to find out which ones are related to that particular process.

    You could download and run the free Process Explorer. By right-clicking on the process showing high memory (Working Set in Process Explorer) and selecting Properties… > Services tab, you'll be able to identify the Services for that particular process.

    Process Explorer doesn't require any installation. Simply run the executable file once downloaded. Then, configure the Process Explorer window to your liking. You can even replace the Task Manager (CTRL+ALT+DEL) by clicking on Options > Replace Task Manager. You'll get a lot more features and details than with the Task Manager.

    You could try stopping one service after the other, while watching the memory usage.

    Press the Windows key + R to open a Run box. Type in services.msc
