I have two machines that the keyboard won't work on the Ctrl-Alt-Del at logon.  Both are WinXP pro sp3.  Both started this today.  The mouse works fine.  My initial thought was that Microsoft really wants us to quit using XP, LOL.

 

I've tried:

Swapping in a known good keyboard,

Making sure connections are good,

Plugging the keyboard into different ports on the computer,

Rebooting, of course

Safe mode

- none of these helped. 

 

I have a hard time believing in coincidences, so I've been seaching to see if there is malware out there that causes this.  I've shut down both as a precaution for now.  Has anyone seen anything like this?

If you are able to boot into Windows.....try resetting using the instructions in link below if you haven't tried doing that.

I agree that what happened is likely more than just a coincidence.

How to change the logon window and the shutdown preferences in Windows XP

 

Have you scanned for malware? If not, scan using the two programs below.....that's if you can boot into Windows.

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • When MBAM is finished scanning it will display a screen that displays any malware that it has detected.
  • Click the Remove Selected button.
  • MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

  • Hold down Control and click on this link to open ESET OnlineScan in a new window.
  • Click the esetonlinebtn.png button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
  • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
  • Double click on the esetsmartinstaller_enu.png icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.
  • NOTE:Sometimes if ESET finds no infections it will not create a log.

I can't get past the logon screen to get into windows, resetting as in the link is a no go. 

 

I will try running a virus scan, but will have to pull the hard drive to do that.  I'm going to set up a different computer to use to scan it with, so I'm not using mine, and I can keep it off the network after get MBAM and ESET installed and updated.

 

Thanks - and I'll post the logs when I get that done.

Edit - I realized I'm not supposed to post logs in this forum.

I've had success on one of them.  After many tries, I was finally able to log into safe mode.  From there I did a system restore, and set it back about a month.  Now I can log on normally, and I ran Malwarebytes.  It found just a few PUP programs, but no real problems.   Now on to the next one. 

 

Thanks for the input.

Since you are finding adware...PUPS....I suggest you scan with these programs, too. Some of those PUPS can easily be called malware due

to all the changes they make in settings, registry and difficulty in uninstalling.

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.
  • download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message
