This is my son's computer. I mention this as it is a fairly unfamiliar machine to me. It is a Dell Latitude D620 running Windows XP Home SP3 with an Intel T2300 @ 1.66GHz and 0.99 GB of RAM (odd number, yes?). He's been having trouble with his media player recognizing his DVDRW drive, it is also extremely slow and for some reason Windows keeps saying his avast! is probably out of date. I've run the avast! virus scanner, also Spybot S&D, Ad-Aware free version, we have Spyblaster installed, and I've run CCleaner. These have picked up nothing out of the ordinary that doesn't appear under regular maintenance and I've taken care of those. Still, the problems persist.

The most pressing is the DVDRW problem. A week ago it worked. When a DVD is placed in the drive now and Windows Media comes up it gives a pop-up window that states: "Windows Media Player cannot play DVD video. You might need to adjust your Windows display settings. Open display settings in Control Panel, and then try lowering your screen resolution and color quality settings." I have tried adjusting the display settings every possible way and even clicked the web help on that pop-up to try and resolve this to no avail. You have helped me so much in the past with problems on my machine I am hoping you can solve this dilemma as well. Any help would be greatly appreciated. I place this post here as I was not sure it belonged in the Malware forum. If this is an inappropriate post for this forum I apologize now.

Please download Malwarebytes Anti-Malware and save it to your desktop.

MBAM 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.
  • 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.
The power of accurate observation is commonly called cynicism by those who haven't got it.

The problem with the avast! seems to be cleared up (strangely, the reason it wasn't up to date apparently was something was stopping it from connecting to the avast! server in order to do so. I couldn't even get to the avast! web site by typing it in or following any link; I now can and it is also updating). However, the problem with playing DVDs is still continuing.
