Question : KeyLogger problems..

Hello Gurus,
I was stunned to discover yesterday that someone has put a keylooger on my pc (Spylo).
I mean WOW ! how can I not have noticed ?
I mean for sure they are supposed to be "invisible" but .....
Anyway my question is : is there a way to know if I have another keylogger on my pc ?
I have to tell that I did not discover myself that spylo was installed on my pc...
I was told !!! so I am afraid of something else...
please help.

Answer : KeyLogger problems..

Keyloggers vary. Some can be detected by traditional programs like anti-spyware programs. For others, you have to use a rootkit detector because they use a device driver to hide themselves from the Windows API.

In your particular case, I suggest using both of the following:

(A) Traditional anti-malware: Autoruns:
(1) Download Autoruns from: http://www.microsoft.com/technet/sysinternals/utilities/Autoruns.mspx
(2) Run the program. It lists a bunch of things that start when Windows starts.
(3) From the menu bar, select Options, and uncheck "Include Empty Locations" and "check" "Hide Microsoft Entries"
    Important -> Then click the Refresh button in the toolbar.
(4) This will give you a shorter, more meaningful list.
(5) Examine that list to see if you can spot a keylogger.
(6) If not, or if not sure, you can use the File -> Save as.. option in Autoruns to save the list to a text file and then cut and paste it here.

In addition to the above, a rootkit detector is a must:
(B) User RootkitRevealer:
Download and run RootkitRevealer from: http://www.microsoft.com/technet/sysinternals/utilities/RootkitRevealer.mspx
and click on "Scan" to scan your drives.
It takes a while, so be patient.
Try not to use the system too much during that time to avoid false positives.
If it produces anything interesting, use "File -> Save As.." to save the
results to a text file (Important -> you may need that file later)
Copy-and-paste the results here, but if the results are very long, then just copy-and-paste the first 30 lines or so.

The above will detect just about every software keylogger. Note that hardware keyloggers cannot be detected by software.
