  No one program cannot be used to detect and remove any malware. Added that often easy

  whenever I select any folder or any icon in my computer win 7 I get a popup to remove this icon why this error comes how can I solve this problem pls help me

  Hello

  1. don't you make changes to the computer until the problem occurred?

  2. What is the exact error message do you get?

  I suggest you try the steps mentioned below and check if it helps.

  Method 1: Start your system in safe mode and check if the same problem occurs.

  http://Windows.Microsoft.com/en-us/Windows-Vista/start-your-computer-in-safe-mode

   

  Method 2 :  If the issue does not exist in Mode safe mode then try to put your computer in a clean boot state.

  By setting your boot system minimum state helps determine if third-party applications or startup items are causing the problem.

   

  How to troubleshoot a problem by performing a clean boot in Windows Vista or Windows 7:
  http://support.Microsoft.com/kb/929135

  Note: After the boot minimum troubleshooting step, follow step 7 in the link provided to return the computer to a Normal startup mode.

  Follow these steps to reset the computer to start as usual:

  (a) click on start toreduce this top that i, type msconfig.exe in the Start Search box and press ENTER.

  If you are prompted for an administrator password or for confirmation, type your password, or click continue.

  (b) under the general tab, click the Normal startup option, and then click OK.

  (c) when you are prompted to restart the computer, click restart.

  Method 3:

  Also scan your computer from the Microsoft Security Scanner, which would help us to get rid of viruses, spyware and other malicious software.

  The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

  http://www.Microsoft.com/security/scanner/en-us/default.aspx

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  Hope this information is useful.

• I can't solve this problem: "Error loading C:\WINDOWS\awuvomas.dll the specific module is not found." Can help you!

  Original title: cannot find awuvomas.dll

  I can't solve this problem: "Error loading C:\WINDOWS\awuvomas.dll the specific module is not found."  Can help you!

  It is sometimes easy to get rid of the error message by doing something like disable the startup item in msconfig (if you can still find), but I suggest you fix the problem and difficulty not only the symptom of the problem by simply deleting the startup message.

  I would also not recommend you start digging in the registry to try to find the startup item and remove it unless you have a backup of your system or at least a backup of your registry, because there is no 'Cancel' or 'quit without saving changes' option in regedit.  If you make a mistake, that's all.

  These ideas relieve 'rapid' and sometimes risky of the symptom if they not even work at all, but they can't actually solve the problem.  Also, I'd be suspicious of ideas that begin with the words "try."  You don't need to try things, you need to fix things.  You don't need to try ideas that might work, you must do something that will always work all the time.

  Here are the detailed instructions that protect you and solve your problem in the 'right' way.

  There is very little. DLL files that should be loaded from the C:\WINDOWS folder and is not one of them.  If you do not have a good explanation for the name of the file in a Google search, the chances are good that your system is currently or has been infected by malware.
  A "Cannot find...". ', ' Failed to start..., "Could not load..." ». "Might not work... "" Cannot run ""error loading... ". "or"specific module could not be found"message at startup is usually related to the malware that has been configured to run at startup, but the referenced file has been removed after a malware scan, leaving behind him a startup item or the registry entry pointing to a file that does not exist.
  It might be a removal of malicious software or an application not installed.  The entry may have a curious looking name since it was probably generated at random when the malware was installed. If you search your system for the referenced file, you may not find.
  Windows attempts to load this file but cannot locate because the file has been deleted for most probably during an analysis of the malware. However, an orphaned associate of remainders of startup parameter or registry entry and tells Windows to load the file when you start or connection.
  So you should delete the referenced entry Windows stop trying to load or run the file. It may or may not be included in the registry, but you can find it.  Autoruns (see below) you get the elements no matter where it is.

  You must be sure to solve the problem and not just fix the symptom of the problem by simply relieving your message - system is not a fix (there is a difference).

  If you just locate and uncheck the item in msconfig, which disables the element but does not remove the reference to the element of false starting your computer.   The msconfig program is not a Startup Manager, that's a troubleshooting tool.  Disabling things in msconfig to put an end to the messages and think that your problem is solved is short-sighted and leave behind him a sloppy XP configuration.  Just disable the display of a start-up error message should not count as a 'solution' to the problem.
  If you are comfortable editing the registry, you can find and remove the reference directly from there or remove it using a popular third-party tool called Autoruns.  The problem can always be found in the registry well.
  Before making any changes to your registry by hand or with third-party tools, don't forget to first make a backup of the registry
  . There is no cancellation or exit without saving the option in regedit.
  Here is a link to a popular registry backup tool:
  http://www.SnapFiles.com/get/ERUNT.html
  You can also use the Autoruns to find the element of start remains little matter where he's hiding.  Autoruns does not install anything on your computer.  It will display all startup locations where the reference may be then you can turn it off or remove it completely.  Here is the download link for Autoruns:
  http://TechNet.Microsoft.com/en-us/sysinternals/bb963902.aspx
  Run Autoruns.exe and wait that he at the end of the filling of the list of entries.
  When the Autoruns is finished scanning your system, it will say "Ready" in the lower left corner.  Autoruns can be a little intimidating to first if you have never seen it before because it displays a lot of information.  You are really interested only a few sections.
  The problem is usually to start the system or the user startup entries, then click the connection tab and see if the startup item is there.
  Scroll through the list and look for a boot entry associated files in the error message.
  If you can't find on the connection tab, look in any tab.
  You can also click file, search to search for logon, or any tab for all or part of the name of the element.
  Right-click on the offending entry and choose Remove.  If you are not sure what it is, you can just turn it off, restart and if the problem is resolved and things are functioning normally and everything works fine, then remove the offending entry.  If you don't see it in Autoruns, you may edit the registry and remove the item from your startup folder it.  Autoruns shall display the same information however.
  Given that your system has or has had an infection, follow up with this:
  Perform scans for malware, and then fix any problems:
  
  No matter what you use for malware protection, follow these steps:

  Download, install, update and do a full scan with these free malware detection programs at:

  Manufacturers recovery disks normally do not have Service Options; they are normally a relocation to the factory only settings option.

  Here is the guide to repair Options using a Vista DVD from Microsoft.

  If a friend or a work acquantance of yours has one, you can borrow and use it for repairs.

  4. Conclusion

  If you do not or can not borrow a Microsoft DVD there is a download of a file ISO of Vista Startup Repair available that you can put on a Bootable floppy to make the above startup repair and that the method is recommended by a large number of posters in these Forums.

  Unfortunately, you have to buy it.

  Here is a link to it:

  There are several methods to reinstall Vista.

  This can help you (download files and make your own DVDs):

  And here are instructions on how to burn ISO disk images:

  ___________________________________

  You can contact your computer manufacturer and ask them to send you a set of recovery disks.

  They should do this for a small fee.

  To reinstall Vista using their recovery disk/s, you start from the 1st recovery disk they provide and follow the manufacturer's instructions to reinstall:

  You need to change the Boot order to make the DVD/CD drive 1st in the boot order:

  ___________________________________

  And if you have never received a recovery disk when you bought your computer, there should be a recovery on the drive Partition hard reinstall Windows how much you bought your computer.

  The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

  Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

  Them or us ask the right sequence of key.

  ___________________________________

  Some manufacturers have more available Vista recovery disks.

  If this happens, you may need to try this instead:

  You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

  Other manufacturers recovery DVDs are should not be used for this purpose.

  And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

  Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

  "How to do a clean install and configure with a full Version of Vista '

  http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html

  And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.

  And phone Activation may be necessary when you use the above installation method.

  Hello

  He got this 1 day, or has it just begun?

  If it was always this way, it could be a manufacturing defect or your advanced display settings may be incorrect. The latter can be determined according to the settings/Advanced/display/personalization in the control panel settings. See Customization here, it varies depending on the manufacturer, but you focus on controls that adjust color output.

  If it has started, then it is possible the monitor had a malfunction. I put another monitor (if available) on the system. If the problem persists, then the fault is in the video card or display drivers. If it disappears, then the monitor can go wrong (you can try to adjust the settings on the screen itself to see if it has no effect). If it turns out to be the graphics card, I would like to firstly download and install a new set of drivers for the graphics card or the manufacturer of the system (the best for download, then uninstall the current set restart and install the new download).
