ISP say my system is compromised

The HJT log doesn't show anything unusual, except perhaps too few entries. Are you sure the above is a complete list as produced by HJT? Also, try renaming HiJackthis.exe to something else like temp.exe and run it again to see if something was hiding from it.

Is this Win2K workstation or Server?

Can you try the following:

(1) Download Autoruns from: http://www.sysinternals.com/Utilities/Autoruns.html

(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"
    Then click the Refresh button in the toolbar.

(4) This will give you a shorter, more meaningful list.

(5) Examine that list and disable anything suspicious by un-checking it. Then reboot and see if it helped.

(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.

P.S. If you can find which port the additional packets are being sent through (aside of some obvious/essential ones) you can just close that particular one. There's a command/utility for doing so but the name escapes me at this moment.

Hi All - Thanks for the input

I renamed the HJT program and the following is an updated report:

Thanks for your time

Pat

Almost forgot - I did pull the network cable

Hi All - I ran the NOD32 package and while the otherprograms found nothing, this found:

W32/XScan

I deleted the file - Was this the cullprit??
Thanks,  Pat

At this point you can attach it to the network (with the Task Manager up to see if any programs start'acting up',and probably the Local Area Connection Status window as well). See what happens. You may find everything's fine until you open up IE. In serveral cases of an infected PC I couldn't find anything until I rebooted the PC and opened up Tack managaer asap---then I'd see one or two programs pop up and disappear (same with the Startup folder in Start\Programs). Run in Safe Mode while connected to the network as well, to further test this. With such a small list of programs running, anything else will stick out like a sore thumb.

And if you want to look for a rootkit, go read this:

http://www.wikistc.org/wiki/Detecting_rootkits

In particular:
http://www.microsoft.com/technet/sysinternals/utilities/RootkitRevealer.mspx


If all's well the system should be running at a low hum with no unusual rev-ups.

Hmm, X-Scan is a tool for checking out vulnerabilities on a PC. A keylogger, too, IIRC. Not sure it would be sending a ton of packets unless it's sending in real-time.

Hi Selvarian -
I have been running this system on the net for about 4 Hours - no problems and no internet activity that was uninvited.  I believe it was your NOD32 suggextion that turned the table

Thanks a million,  Pat
