Good Day Forum,

 

Name is Ivan.

I guess I'll start of with some details about my system and the issue I'm having.

It is a bit unique given the OS isn't the usual XP, it is Windows XP "Embedded", but I'm hoping it's not something that will hinder your ability to help me.

Now the issue is, and I'll be straight up honest, I'm assuming has to do with a P2P filesharing and is very similar in it's essence to the FBI virus.

 

* The USB keyboard locked out and render the naviagation keys useless upon entering the Boot Menu.
* Windows does not boot past the splashscreen.

I was able to get the keyboard to work by using a PS/2 Adapter I had on hand, giving me the ability to navigate through the Boot Menu and moved on to the next step.

 

Since my problem symptoms closely resembled the virus mentioned, I have proceded to follow the basic solution people use.

Downloaded HitmanPro App and attempted to make a bootable flashdrive. But unfortunately the only other computer I have is a 64bit Windows machine and I couldn't run a 32bit version I would need to use for the Infected (I'm assuming) machine.

 

With the Hitman app off the list of quick solutions I turned to AVG Rescue tool which is said to be less sensitive to the version of OS and was faced with yet another issue. When in Boot Menu and attempting to choose USB FDD (Flashdrive?) or any other option, the machine still attempts to boot from HDD and I'm hit with the windows splashscreen that loads for a few seconds and screen goes dark.

 

I'm kinda limited in what I can do given this machine has no CD drive, so I'm limited to using USB for any tools...however...if needed Im willing to go ahead and install a cd/dvd drive or gain access to a 32bit machine to make the bootable Hitman flashdrive or anything else if it brings us closer to resolving the issue.

Hope I'm posting in th right forum and not being a pest. Looking forward to hearing from you guys, I need to fix this machine since I use it for work and my ability to pay bills depends on it directly.

Thanks,

Ivan

Update.


Got a 32bit version of Hitman app and made bootable Flash drive.

Got into Boot menu with a PS/2 keyboard.

 

Took a few tries to get it to boot from flashdrive, but in the end Windows started up and let me log in.

 

Prior to log in I get an Error titled "savedump.exe - Entry Point Not Found" ...and message:

 

The procedure entry point SymSetSymWithAddr64 could not be located in the dynamic link library DBGHELP.dll


Mouse works, but the system stopped recognizng PS/2 keyboard, so I hooked up one through USB and was able to log in.

 

Everything loads up alright and seems to be in order, except a few files system files missing (i.e. vidcap.ax; i8042prt.sys) and I get a message to insert a Windows XP Pro Service Pack 3 (never had one)

 

I have scanned the system with Hitman - no threats found except a few tracking cookies.

 

I'm not exactly computer savvy when it comes to dealing with anything that wouldn't let Windows boot, but overall a very strange case here. I don't even know what happened or if the tools I used are responsible for my problem's resolution.

I got no responces anywhere I went online...perhaps because I have weird Windows chopped up speciffically to deal with my machine's firmare (it's a desktop Dental 3D Scanner)...so, I just have a message to anyone having any problems - Don't give up. ;)

 

Not to say this forum didn't help me at all, lots of great material here and I'll be sticking around to read up more. Thank you all for being here, keep up the great work.

 

All Best,

 

Ivan

The following may help you with the error message you are getting :

 

http://www.raymond.cc/blog/fix-startup-error-symsetsymwithaddr64-not-located-in-dbghelpdll/

 

and it was also discussed here on BC - at considerable length ! - in September 2006:

 

http://www.bleepingcomputer.com/forums/t/64564/symsetsymwithaddr64/

 

I just had a quick look at the BC article and noticed that one of the points made was to get rid of any P2P applications on the computer.

 

You say that this computer is a 'Dental 3D scanner', which is why it has an embedded OS. I must admit that I am impressed that you have got it to work so far out of its design envelope as to be able to run P2P software on it. Computers, particularly PCs, are essentially general purpose machines which means that you can run software on a general purpose OS to do almost anything. I always understood that embedded OSs were for restricted and specialised systems, a typical example being to run the electronic control system in a car. I have a Ford Mondeo which has a fairly powerful computer structured into it, but I wouldn't dream of trying to get it to write a letter for me !  But then, I wouldn't ask my desktop to take me to the local supermarket.

 

You say that you got into the 'Boot menu'. Do you mean that you got into the BIOS or just to the 'Boot options' screen ?  If you got into the BIOS, you could try changing the boot priority order to move 'USB' up the priority list.

 

As for the other things you mention. You don't have a built in CD/DVD drive, but you do have at least 2 USB sockets. You can get external USB connected optical drives. And as you are running a version of XP, you really should have this updated to SP3. You can download the update file from MS either for burning to a CD - which is what I did since I had several computers in my care running XP - or save it to a memory stick. It is in the form of an .EXE file and it is about 320MB in size and you just run it from either the CD or the memory stick.

Hi,

 

You can download DBGHELP.dll which contain the entry point SymSetSymWithAddr64 here:

http://www.opendll.com/index.php?file-download=dbghelp.dll&arch=32Bit&version=5.1.2600.5512&dsc=Windows-Image-Helper

 

  1. Make a backup of DBGHELP.dll located in c:\windows\system32
  2. Download the DBGHELP.dll and extract it in c:\windows\system32
  3. Reboot

 

This is the Windows XP version, all other versions from Version 6 and above doesn't contain this function anymore.

 

I hope this help
