![]() Have you ever looked at an advertisement or Tech Support Scam (TSS) popup and wanted to know which process was responsible for it? Sometimes, these pop up as windows without title bars (if they do, they're misleading). Note: The resulting text file will start with a list of the running processes followed by the list shown in the lower pane. You can send the text file to the person helping you. If you want a second opinion this can be very convenient. A “Save As” dialog box will open and allow you to save the details as a text file. You can also export the list for a process by selecting the process you are interested in, in the Upper Pane (processes) and clicking on the “Save” symbol in the upper left corner (or use Ctrl+S). Then you can chose between DLLs and handles. To use this option, you have to click the “View” menu and enable the “Show Lower Pane” first. Note: Some security programs may flag the intercepted calls done by Image File Execution Options (IFEO) as potentially unwanted.Īnother feature that often comes in handy when you are trying to figure out what’s going on is the option to check the DLLs and handles that are in use by a certain process. ![]() ![]() ![]() Using this will open Process Explorer with every call to taskmgr.exe, including the key combination “Ctrl-Alt-Del”. On the Process Explorer window, under “Options” menu, you will find “Replace Task Manager”, which requires Administrator privileges. If you would like to replace Task Manager with Process Explorer, it offers an easy way to do this. Besides the options the regular Task Manager has to offer, there are a few extra ones that are particularly interesting when you suspect your machine to be infected. It offers a much clearer view of what is going on and has a lot more options. For Windows operating systems (OS), especially those up to and including Windows 7, Process Explorer is an excellent replacement for Task Manager.

Xplorer2_64.exe pid: 108904 type: File 1098: C:\Users\me\AppData\Local\Microsoft\Windows\Explorer\iconcache_32.db Sysinternals - xplorer2_64.exe pid: 108904 type: File 844: C:\Users\me\AppData\Local\Microsoft\Windows\Explorer\iconcache_32.db Here is an example output: →handle -a "C:\Users\me\AppData\Local\Microsoft\Windows\Explorer\iconcache_32.db" SysInternal's handle utility is designed exactly for this problem for the command line. Status = ntdll.NtQueryInformationFile(hFile, ref(iosb), # system call to retrieve list of PIDs currently using the file = (įILE_INFORMATION_CLASS) # In FileInformationClass PIO_STATUS_BLOCK = ctypes.POINTER(IO_STATUS_BLOCK) Info = FILE_PROCESS_IDS_USING_FILE_INFORMATION() ('ProcessIdList', wintypes.LARGE_INTEGER * 64)) _fields_ = (('NumberOfProcessIdsInList', wintypes.LARGE_INTEGER), Raise ctypes.WinError(ctypes.get_last_error())Ĭlass FILE_PROCESS_IDS_USING_FILE_INFORMATION(ctypes.Structure): Path, FILE_READ_ATTRIBUTES, FILE_SHARE_READ, None, OPEN_EXISTING, Wintypes.DWORD, # In dwFlagsAndAttributes Wintypes.DWORD, # In dwCreationDisposition LPSECURITY_ATTRIBUTES, # In_opt lpSecurityAttributes # create handle on concerned file with dwDesiredAccess = FILE_READ_ATTRIBUTES INVALID_HANDLE_VALUE = wintypes.HANDLE(-1).value Kernel32 = ctypes.WinDLL('kernel32', use_last_error=True) have a look at the following code in Python which returns a list of PIDs that can then easily be killed using the Task Manager or similar tools. You can also do it programmatically by leveraging on the NTDLL/KERNE元2 Windows API.
