I think I have had multiple infections, and the one which got my attention yesterday was the "NewDotNet" problem which I fixed up using a tool from Symantec.

BHODemon kept telling me that I had a new BHO - it was called "byxurom.dll" and from my research it seems to be a random name. I was able to delete the dll, but I cannot get rid of the registry entries - they keep coming back.

I thought I'd boot in safe mode to try to get rid of the registry entries, but no matter what I did the machine would not come up in safe mode. The symptoms were that after hitting F8 I'd get the normal choice of boot and select "safe" the PC would then just proceed to boot into normal mode.

Looking at your site I found the alternate way to boot into safe mode in a tutorial. I set the msconfig as per the tutorial, and now I'm in deeper trouble than before.

When I try to boot the PC just goes blank for a while then I get the XP Pro splash screen for a few seconds bofore the screen goes blank again then after a few seconds the splash screen is back and this just cycles around for as long as I leave it.

It seems that one of the infections I had has set something to prohibit safe mode, and now that I have a boot file demanding safe mode it will not boot at all.

I have forgotten everything I used to know about DOS, but I tried booting from a floppy and it would not let me see the C: drive - not sure if it is my crap memory for DOD commands or a real problem but the result is the same.

When it came up with an A> prompt I typed C: and it says "invalid drive specification" or similar - and I don't know what to do next. I was going to try to find and rename the boot.ini file to see if that would help but I'm stuck where I am.

Unfortunately I couldnt run all the diagnostics you suggested, but I have run Search and Destroy which did kill some stuff and was clear when I ran it again later.

What was happening just before I locked the PC up for good was that WinPatrol kept on reporting that a new startup program "winlogon:shell" was installed. I answered no to not keep it, but it would come back within a minute or so.

Can you help.

BTW I have attached the HijackThis log I took before I got stuck here.

You should print out these instructions, or copy them to a NotePad file for reading while in Safe Mode, because you will not be able to connect to the Internet to read from this site.

Please download SmitfraudFix (by S!Ri)
Extract the content (a folder named SmitfraudFix) to your Desktop.

Next, please reboot your computer in Safe Mode by doing the following :
  • Restart your computer
  • After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
  • Instead of Windows loading as normal, a menu with options should appear;
  • Select the first option, to run Windows in Safe Mode, then press "Enter".
  • Choose your usual account.
Once in Safe Mode, open the SmitfraudFix folder again and double-click smitfraudfix.cmd
Select option #2 - Clean by typing 2 and press "Enter" to delete infected files.

You will be prompted: "Registry cleaning - Do you want to clean the registry?"; answer "Yes" by typing Y and press "Enter" in order to remove the Desktop background and clean registry keys associated with the infection.

The tool will now check if wininet.dll is infected. You may be prompted to replace the infected file (if found); answer "Yes" by typing Y and press "Enter".

The tool may need to restart your computer to finish the cleaning process; if it doesn't, please restart it into Normal Windows.

A text file will appear onscreen, with results from the cleaning process; please copy/paste the content of that report into your next reply along with a new hijack log.

The report can also be found at the root of the system drive, usually at C:\rapport.txt

Warning: running option #2 on a non infected computer will remove your Desktop background.

1. Download this file :


2. Double click combofix.exe & follow the prompts.
3. When finished, it shall produce a log for you. Post that log and a HiJack log in your next reply

Do not mouseclick combofix's window while its running. That may cause it to stall

Download AVG Anti-Spyware from http://www.ewido.net/en/download/ and save that file to your desktop. Note: This is NOT the Anti Virus from AVG.

When the trial period expires it becomes feature-limited freeware but is still worth keeping as a good on-demand scanner.
1. Once you have downloaded AVG Anti-Spyware, locate the icon on the desktop and double click it to launch the set up program.
2. Once the setup is complete you will need run AVG Anti-Spyware and update the definition files.
3. On the main screen select the icon "Update" then select the "Update now" link.
o Next select the "Start Update" button. The update will start and a progress bar will show the updates being installed.
4. Once the update has completed, select the "Scanner" icon at the top of the screen, then select the "Settings" tab.
5. Once in the Settings screen click on "Recommended actions" and then select "Quarantine".
6. Under "Reports"
o Select "Automatically generate report after every scan"
o Un-Select "Only if threats were found"
Close AVG Anti-Spyware. Do Not run a scan just yet, we will run it in safe mode.
1. Reboot your computer into Safe Mode. You can do this by restarting your computer and continually tapping the F8 key until a menu appears. Use your up arrow key to highlight Safe Mode then hit enter.

IMPORTANT: Do not open any other windows or programs while AVG Anti-Spyware is scanning as it may interfere with the scanning process:
2. Launch AVG Anti-Spyware by double clicking the icon on your desktop.
3. Select the "Scanner" icon at the top and then the "Scan" tab then click on "Complete System Scan".
4. AVG will now begin the scanning process. Please be patient as this may take a little time.
Once the scan is complete, do the following:
5. If you have any infections you will be prompted. Then select "Apply all actions."
6. Next select the "Reports" icon at the top.
7. Select the "Save report as" button in the lower lef- hand of the screen and save it to a text file on your system (make sure to remember where you saved that file. This is important).
8. Close AVG Anti-Spyware and reboot your system back into Normal Mode.
Post the log from AVG and a new HiJack log

Thanks for your comprehensive response.

Unfortunately I am not able to complete the instructions as I still cannot boot the PC in safe mode (or any other mode for that matter).

When I power on initially I get the IBM bios screen, then if I hit F8 I get the option to select safe mode as usual.

When I select safe mode the screen displays a lot of drivers being loaded (seems normal although I don't know what all the drivers do) then the machine automatically does a power cycle.

It's as though that the virus or spyware I have been infected with has inserted a power down instruction into the safe mode startup sequence and that is how it forces safe mode to always end up in normal mode.

Unfortunately as a result of my msconfig changes I now have a boot.ini (I guess) which mandates safe mode so I'm stuck in a loop!

Is there any way for me to bypass this or must I re-install XP from scratch?

Thanks again,
