If you don't know what a process is or you come across a suspicious file, search the name using Google, or the following links:
BC's File DatabaseBC's Startup Programs DatabaseFile Research CenterProcess ID DatabaseHow to determine what services are running under a SVCHOST.EXE processDetermining whether a file is malware or a legitimate process sometimes depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location on your computer. A file's properties may give a clue to identifying it.
Right-click on the file,
Properties and examine the General and Version tabs.
You can download and use
Process Explorer or
Glarysoft Process Manager to investigate all running processes and gather additional information to identify and resolve problems. These tools will show the process CPU usage, a description and its
path location. If you right-click on the file in question and select properties, you will see more details about the file.
The Process Explorer window shows two panes by default: the
upper pane is always a process list and the
bottom pane either shows the list of DLLs loaded into the process selected in the upper pane, or the list of operating system resource handles (files, Registry keys, synchronization objects) the process has open. In the menu at the top select View > Lower Pane View to change between DLLs and Handles.
If you have XP Pro, you can use
Tasklist to display a list of active processes.
Go to Start > Run and type:
cmdpress Ok
At the command prompt type:
tasklist /svc >c:\taskList.txtpress Enter
Go to Start > Run and type:
C:\taskList.txtpress Ok to view the list of processes
The /SVC switch shows the list of active services in each process. For help and syntax information, type the following command, and then press ENTER:
tasklist /? or see: Syntax optionsYou can also use the
WMI command-line utility to view and list processes.
Go to Start > Run and type:
cmdpress Ok
At the command prompt type:
WMIC /OUTPUT:C:\ProcessList.txt PROCESS get Caption,Commandline,Processidpress Enter.
You can also use (type):
WMIC /OUTPUT:C:\ProcessList.txt path win32_process get Caption,Processid,Commandlinepress Enter.
Go to Start > Run and type:
C:\ProcessList.txtpress Ok to view the details of all the processes.
Anytime you come across a suspicious file which you cannot find any information, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to
jotti's virusscan or
virustotal.com. In the "
File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
Post back with the results of the file analysis.
