Question about Toshiba Satellite M45-S331 Notebook

1 Answer

About 2 weeks when scanning Norton antivirus found two registry problems when full scan was run about 2 days apart. The registry components were deleted. I also noticed other problems with the machine, slower than usual. I decided to use the system recovery cd to do a complete restore. Now, the computer does not recognize the cd-rom when installed. When I install the cd-rom, sometimes I see the cd-rom icon flashing on the desktop. However, when I click my computer, then click on the cd-rom icon I get: D:\is not accessible The request could not be performed because of an I/O deivce error. When I right click the CD-ROM icon, select properties, Hardware Tab, Highlight CD-ROM Drive, Properties, Device Status: This device is working properly. I've gone to the Toshiba Web Site and dowloaded the driver for this machine and rebooted. I've also tried the Windows update driver for this device which had an earlier date than the Toshiba driver but installed it anyway. Neither driver fixed the problem. So I re-installed the driver from the Toshiba site. In the BIOS I checked for the devices: HDD is IDE primary and ODD IDE secondary. Any other ideas? I have goggled this problem and have noted that registry problems may cause these symptoms. Can't use the restore CD - what tools can I use to fix this problem?

You should be able to call Norton and they should be able to assit you. If they do not I would suggest using the free microsoft antivirus and spyware solution. Do a google search for Microsoft Security essentials and that should find you the link. If you need to do an online scan you can go to http://safety.live.com which will re-route you to a onecare site that has an online scanner. You will need to install the activex components which will either appear above the webpage below the Internet Explorer address bar or will pop up a box to install. Microsoft will remove this at a future date so don't be suprised if the online scan dissapears. If you do the full scan it will defrag the machine and do a registry repair which can fix a lot of issues.

Install an updated full version of antivirus. Your antivirus might-be-out of date. I recommend you to use avast or avg 8. They will remove all the viruses they detect from your system. But remember to install only one antivirus because installing more than one antivirus can clash down your computer. After installing the new antivirus, scan your computer and delete all the detected viruses. Delete also your temporary internet files, cookies, cache,etc. To do this, follow these steps:
  • Go to Start, Control Panel.
  • Network and Internet Connections
  • Internet Options
  • In the Browsing History, click Delete...
  • Delete Browsing History box appears, Click Delete All button found at the bottom.
  • Reboot your computer.

How do i get rid of a W32.SillyFDC virus


The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.
  1. Disable System Restore (Windows Me/XP).
  2. Update the virus definitions.
  3. Run a full system scan.
  4. Delete any values added to the registry.

For specific details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:

Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article: Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Article ID: Q263455).

2. To update the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:
  • Running LiveUpdate, which is the easiest way to obtain virus definitions.

    If you use Norton AntiVirus 2006, Symantec AntiVirus Corporate Edition 10.0, or newer products, LiveUpdate definitions are updated daily. These products include newer technology.

    If you use Norton AntiVirus 2005, Symantec AntiVirus Corporate Edition 9.0, or earlier products, LiveUpdate definitions are updated weekly. The exception is major outbreaks, when definitions are updated more often.


  • Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them.

The latest Intelligent Updater virus definitions can be obtained here: Intelligent Updater virus definitions. For detailed instructions read the document: How to update virus definition files using the Intelligent Updater.

3. To run a full system scan
  1. Start your Symantec antivirus program and make sure that it is configured to scan all the files.

    For Norton AntiVirus consumer products: Read the document: How to configure Norton AntiVirus to scan all files.

    For Symantec AntiVirus Enterprise products: Read the document: How to verify that a Symantec Corporate antivirus product is set to scan all files.


  2. Run a full system scan.
  3. If any files are detected, follow the instructions displayed by your antivirus program.
  4. Delete the autorun.inf file from writeable removable devices, if necessary.
Important: If you are unable to start your Symantec antivirus product or the product reports that it cannot delete a detected file, you may need to stop the risk from running in order to remove it. To do this, run the scan in Safe mode. For instructions, read the document, How to start the computer in Safe Mode. Once you have restarted in Safe mode, run the scan again.


After the files are deleted, restart the computer in Normal mode and proceed with the next section.

Warning messages may be displayed when the computer is restarted, since the threat may not be fully removed at this point. You can ignore these messages and click OK. These messages will not appear when the computer is restarted after the removal instructions have been fully completed. The messages displayed may be similar to the following:

Title: [FILE PATH]
Message body: Windows cannot find [FILE NAME]. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

4. To delete the value from the registry
Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. For instructions refer to the document: How to make a backup of the Windows registry.
  1. Click Start > Run.
  2. Type regedit
  3. Click OK.

    Note: If the registry editor fails to open the threat may have modified the registry to prevent access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.

  4. Navigate to the following registry subkeys:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
    HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows\"load"

  5. In the right pane, delete any values associated with the worm.


  6. Exit the Registry Editor.

I've already purchased Norton antivirus 2008 with antispyware and loaded but my screen still blue and shows Warning spyware detected in computer & to install antivirus or spyware wich i did.


That blue screen sounds like a trick to me. Many viruses and spywares or the websites that distribute them make beleive that they are causing viruses then provide links to fake antivirus and spyware removal programs that actually make your system worst.

Use the Norton to purchased to do a full deep scan of your system. I also like to supplement my Norton by running the free scan at housecall.trendmicro.com when I suspect there might be a problem on my machine that Norton can't fix.
