  • I would ask this in the AVG Forums:



    or Windows server forums:



    Please follow the steps below:


    1. Reboot your machine.

    2. At the start-up screen, please press F8 and select the Safe Mode.

    3. After you enter the system, select the anti-virus software to scan all disks.

    4. At the start-up run, please input Msconfig and disable the suspicious startup items.

    5. How to display the hide items in system:

        Driver C>Folder options>view>show hidden files,folders,and drives>uncheck the Hide protected operating system files>

    6.After the scan finishes, please reboot the system the try it again.

    Your expertise never fails to impress :)

  • Disable the System Restore. If this is still turned on, the system will restore any deleted files, including those infected by the Trojan horse. This can be done by going into the My Computer file and looking for the Performance option. Then select File System, Troubleshooting and Disable System Restore.
    Turn on the computer and run it in safe mode. Restart the computer and when the words begin appearing on the screen, press the F8 key. This takes you to a new screen, where you'll select the safe mode option.
    Go to the Control Panel by clicking on the "Start" button at the bottom left-hand side of the screen and looking for the Control Panel. Select the Add or Remove Programs icon. The computer should then show a list of all programs existing on your system.
    Look for programs that include Spyware or adware on your computer and select the Remove program option. Many users have found it helpful to look for programs that they didn't install and those that were installed when they downloaded a game or other program onto their computer.
    Open the Windows System folder and delete all files that include the Trojan virus extension. Go through the list twice to make sure you removed all virus files. Then restart the computer in normal mode and check the folder again. If all the files are gone, you'll be ready to move on. If there are any remaining, remove them and restart the computer.

  • Did you try pulling the hard drive out and accessing your data from another computer?
    You will likely have to modify the file system permissions in order to access your data.
    Its hard to say for sure unless you know exactly what virus nailed you.

  • Hi

    First I would recomend you use Avast. This is really a awsum anti virus program and the best thing of all its free!!! :-) !!! it would preven this from happening in the future.

    K once you have installed Avast on your PC just reboot and do a bootime scan during the install i think it would prompt you for the boot time scan. You can download it from www.avast.com

    Hope this resolves your problem.

  • The bad thing about Trojan Horses: Trojan Viruses are quite difficult to find.

    I would suggest you to install avast antivirus to remove trojan from your system. I am also using it on my machine. It is an awesome product.

    You can also try to clear the temporary internet files and delete them manually.
    Please refer following site for more information :


    Hope, it helps

  • Dear Jenny,

    Sorry to hear that your system is infected with Trojan Horses! These kind of infections have proven to be extremely tough to detect and remove. However, there are some tricks to removing them 100-percent, but require technical know-how!

    Now, if your current antivirus/antispyware combo software do not support boot-time scans, you can download and install Avast. Make sure that this feature is enabled during setup, then restart the computer and perform boot-time scan. Remember to turn-off system restore before performing those functions. Upon completion, your PC should be free of Trojan Horses. If you need more advanced tips, chat with virus removal support experts today.

  • The Microsoft Windows Malicious Software Removal Tool checks Windows Vista, WIndows 7, Windows XP, Windows 2000, and Windows Server 2003 computers for and helps remove infections by specific, prevalent malicious software—including Blaster, Sasser, and Mydoom. When the detection and removal process is complete, the tool displays a report describing the outcome, including which, if any, malicious software was detected and removed. The tool creates a log file named mrt.log in the %WINDIR%\debug folder.

    Microsoft® Windows® Malicious Software Removal Tool (KB890830) 

    This tool checks your computer for infection by specific, prevalent malicious software (including Blaster, Sasser, and Mydoom) and helps to remove the infection if it is found. Microsoft will release an updated version of this tool on the second Tuesday of each month.

    Its free, effective and afterwards do not forget to run Security Essentials to ensure the virus has been removed.

    All the best

  • Boot via active boot disc.. you can download it.. and is free.. therefore backup all your data.. via safemode... in any case.. re-install your OS will be the best choice :D don't bother wasting the time to troubleshoot it.. in any case if you wish to troubleshoot.. you might need to proceed with registry hive troubleshooting.. which is a total waste of time.. haha grab your files and reinstall the OS :D

  • I have had this issue on two xp clients of mine, first, if the " fake viruse software" is up on the screen, go to taks manager, right click on the application and then click " go to proceess" copy the file path and past it into the run line ( you will need to enable show hidden files) delete the .exe file that is causing that trogan to run. next run spybot , malware bytes and smith fraud fix.  once you have removed the malware, run your antiviures program ( should say this is easier in safe mode) once the machine is clean, i would suggest if its xp to uses an oem xp cd and do a repair istall so that all of your hidden files are get their correct file permissions, i you are on the newerv os that microsoft thought it would be a great Idea to get rid of the repair isntall, then you will have to do a mass un hide.. I have not found an easy way to do this, however, It appears that folders witht he OEM hidden permissions will not allow you to set them to un hidden, so I have tried in the past to try to right click on a root folder un check the hidden folder and allow it to apply to sub folders, when it gets to a folder that is suppose to be hidden you will get an error and have to tell it to skip...


    good luck

  • Hi Jenny, a virus could not be removed, may be:

    1, the virus could not be detected by the anti virus;

    2, the Virus was picked up, but could not be removed as the virus process could not be terminated;

    3, the virus was picked up and removed, but the virus keeps coming back.

    If you are an ordinary user, please do the following:

    1, turn off System Restore;

    2, delete Internet Temp files;

    3, disconnect the network and take a full system scan for virus. Quarantine or remove the virus when prompted; Restart PC. If the virus is still there, go to step 4 and 5.

    4, Check Startup menu from Start --> All  programs -- Startup and delete suspicious programs;

    5, Windows Key + R to bring up Run Box, type in MSCONFIG and then hit Enter, click Startup tag, uncheck suspicious programs. Click OK to quit and restart your computer.

    6, Make sure the virus is not being scheduled to download from the internet again. Please click Start --> All Programs --> Accessories --> System Tools --> Task Scheduler. Under Active Tasks, disable suspicious tasks.

    7, Run the Anti Virus in Safe Mode. If it is successful, please turn the System Restore back on. If no luck still, please let us know the virus program name here. We would try to help you further.

    If you are super user, we would post more advanced techniques to help you further.

  • Yes you are right! I also encountered a trojan Trojan.Spy.Banker.AGD that slow down my PC entirely. I removed it immediately by scanning my whole computer. You can also scan your computer with antivirus.
