» The file svchost.exe is the Generic Host Process for Win32 Services used for administering 16-bit-based dynamically linked library files (DLL files) including other supplementary support applications. As operating systems became more complex Microsoft decided to run more software functionality from a dynamic link library (DLL) interface. However DLLs are unable to launch themselves and require at least one executable program, i.e. svchost.exe, is needed to bridge between the library process and the operating system.

What that means is that several services are hosted within a single SVCHOST. These services are grouped logically based on their functions. For example several service pertaining to the updating, user interface, or the firewall could be grouped together. Thus, if one SVCHOST crashes it may not necessarily impact the entire functionality of the Operating System.

Why is it consuming so much of my CPU? To answer this question you first need to identify what processes are running under that particular SVCHOST. The following will walk you through creating a text file with information regarding the running processes. Once we have this information we can determine how to proceed from there.

How to determine what is running under SVCHOST.exe

1. Open Task Manager, click View, click Select Columns, click PID (Process Identifier), and click OK.

2. Locate the PID for the svchost.exe with the high CPU usage – document this number.

3. Now click Start, click All Programs, click Accessories, and then click Command Prompt.

4. Type tasklist /svc >%homepath%\Desktop\results.txt

5. This will output the results to a text file on your desktop. 6. Copy and paste that information into your reply, and indicate the PID number you gathered initially.

When being inflicted by the exe virus (TrojanDropper:Win32/Bifrose.F), CPU will be highly used and cause the slowdown of the operating system. here is a program for you to scan the computer for registry errors and fix related viruses. Download DLL Suite and run it, click its "DASHBOARD" menu and then click the Scan button, it will automatically analyze the error and remove .exe virus infection for you.

DONALD HAMPTON replied on March 18, 2013: » An alternate method when using Process Explorer is to double click on the Graph just below the Menu bar.This will open the 'System Information' window, which has a larger display of all three graphs. Move your mouse over any spike in the CPU Usage graph to see what process/application or service is the cause of the spike in CPU loading.
