do a clean install?
it has been cleared of all infections for 2 months now but I still can not get the sound back to "normal"
I have tried a number of walk throughs but still no good.
I attempted to post this earlier but it failed and not about to post all the details again to have it fail and not save what i had typed.. so I will post what it was infected with and leave it at that. and woek on the files infected and post it later for now I am not going through the whole thing...in case I get another error about posting.

infected with:

win32 crypt-hef drp
win32 trojan-gen
vbs malware-gen

one file infected was this which I thought was the reason why the sound was damaged but I have done what i can with that and it didnt seem to help:
system volume information]_restore{d205ca-2303-4F70-B721-CE3347E680F6}RP75

I have gone through the step of turning off system restore and then turning it back on and also removed sound from device emanager and rebooted to reinstall for back up files and that doesnt help
I have taken the laptop apart and cleaned out the inside of the laptop and checked for bad circuits but nothing appears to be fried.. on board diagnostics indicate that the sound is working fine,,,
I have reinstalled the driver for the sound which is sigmatel. and I now have as many of my files copied if I need to do a clean install I will.. which I am thinking may be my best chance at it getting as close to normal as i will possibly get.. and detemine if it is an issue with the onboard sound card or a software or driver related issue. not an incompatible issue as it was working fine for 3 years.
it began after the computer virus scan completed and moved the infected files to the virus chest.. hasnt worked right since.
any input.. thanks in advance..

Hello and welcome. system volume information]_restore this is where the Restore points are kepy. That volume is the type likes a book would be a volume of information. Malware can be there as found and you removed it when you emptied it.

Let's do 2 scans and be sure your clean.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Troubleshoot Malwarebytes' Anti-Malware


Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.

I am beginning this right now but the links you supply indicate that the file is corrupt on Malwarebytes' Anti-Malware first link is corrupt file second is a redirect to the first link . I went to the main website and downloaded the free copy http://fileforum.betanews.com/detail/Malwarebytes-AntiMalware/1186760019/1 it is presently installing.
I can bet there is no infection, but I have turned off my antivirus scanner and i am install this program presently I should be back within the hour to post results of this one then will proceed to the next suggested.

It probobly is not an infection but we had to be sure as many infections,hide in driver or .exe files..
I ould ask in WinXP forum how to check your system files or sound files.

all is clear had trouble I kept stopping the ESET program by accident and had to keep restarting it.. finally managed to get through after 2 hours and 10 minutes without stoping it half way into a scan... Murphy loves me.. anyway
Laptop is clean and would love to know if there is a way to recover the sound without having to do a clean install.. suggestions please?? thank you

before i forget one of the warnings i got was it was so long ago and I can't recall but it had something to do with java and download it was the last part of removing the infection thought i should mention that

What version of JAVA is running?
Go into Control Panel>Add Remove Programs. Be sure the 'Show Updates' box is checked. Go down the list and tell me what Java applications are installed and their version. (Highlight the program to see this).


We can run the System File Checker here and see if that is where the sound issue is .. If not you will need to ask about this in XP or the sound forums and they will check your drivers.

SFC

Please run System File Checker sfc /scannow... For more information on this tool see How To Use Sfc.exe To Repair System Files

NOTE for Vista users..The command needs to be run from an elevated Command Prompt.
Click Start, type cmd into the Start/Search box,
right-click cmd.exe in the list above and select 'Run as Administrator'


You will need your operating system CD handy.

Open Windows Task Manager....by pressing CTRL+SHIFT+ESC

Then click File.. then New Task(Run)

In the box that opens type sfc /scannow ......There is a space between c and /

Click OK
Let it run and insert the XP CD when asked.

Thanks But I am dell tech certified and retired so being that I am confident it is no longer infected I proceeded to do a repair on windows with the OS install disk and f12 option and I choose the repair ® windows option, as I have spent enough hours running scanners and cleaners on the system and removed all evidence of infection.
I have my sound back to normal and found there were in fact a number of system files that needed to be repaired.

Now that they are fixed I ran all the windows updates and my laptop is back to running prefectly fine without loosing all my files and programs which would be the case with a clean OS install.

I know as a fact it is not always that the repair option works but this time it did very well..
thank you for your offer to help, but as I said, I was tired of the time it has taken and wanted the ordeal behind me rather fast ..with out anymore delays.
I do appreciate the answer.. but I already went ahead and just did what I planned on doing and was prepared to do a clean install if it didn't work out right.

These scanners and process testing take far too long for me to bother with.. but thanks anyways..
I thought possibly someone may have known the answer to edit the registry or something to avoid the time it took to repair the OS.. but either way now I am running as i was before..without incidence...
