I suspect that your CL account may have been compromised. I would recommend that you contact the tech support team using the Craigs List online form.

In the interim, you should consider changing your Craigs List password.

Step 1: Let's prepare for getting rid of "Windows cannot find" error message

First of all, backup your registry. The good idea is to create Windows Restore Point. This can save your operating system in case of emergency.

Open Regedit and Msconfig programs. We'll need them both. If infection got deep, I recommend you searching for and downloading a program called Autoruns, which shows and allows to disable much more autorun entries than standard Msconfig.

Step 2: Searching for the file Windows cannot find ourselves

Remember the name of file from "Windows cannot find" dialog. The first question we should ask ourselves is whether this is legal Windows file (or some needed file) or whether this is a malicious lookalike.

Here is the short list of files which are commonly missing and which are legal Windows files if situated in Windows\System32 folder or one of its sub-folders:

svchost.exe

spoolsv.exe

rundll32.exe

regsvr.exe

msconfig.exe

And here is the list of files that are not legal Windows files, which are, in fact, malicious files, but look like the legal ones:

schost.exe

ssvchost.exe

svch0st.exe (notice zero instead of letter)

spoolsv32.exe

rundll.exe (such file really existed on Windows 9x, but should not exist on newer version of Windows, otherwise it is malicious)

run32dll.exe

There are, of course, a lot of other possible malicious file names that resemble legal files. Just turn on your imagination and use common sense to determine whether you faced with legal file or with somethign malicious in your "Windows cannot find" error message.

Step 3: Restoring legal files that Windows cannot find

If Windows is missing some really legal and system-critical file, you can restore it by executing the following command in command prompt window:

sfc.exe /scannow

This command may require you to insert original CD or DVD from which you installed Windows.

Step 4: Examining startup items and services

The next step in fixing "Windows cannot find" problem is to find erroneous references to files from registry, start items and services. Download the program called HijackThis here which will scan and show you all startup items and services on your computer.

Step 5: Repair Registry--you can use some secured program such s McAfee secured RegInOut to recover missing file. Thanks
