Learn and install a choice OS such as Mac OS X or Knoppix or FreeBSD, on a new hard drive, and carefully migrate any data you need to keep from the old drives.

You have been quite vague about why you can't use your computer in your query and why you think it's a trojan, which got past Norton (rather than you.) That won't help, as what has to change bar none is the vulnerability your system's fallen to.

Alternately to the new OS, you can boot to a clean environment in a more tenative way, for example by buying a new hard drive and installing whatever you had to that, or using a LiveCD (LiveDVD, live USB key distro, etc.) Windows tends to mount new drives promiscuously though, so you need to be very careful when booting up with your old drive reconnected so that you do not 'autorun' your old virus or whatever! Even then you need to know you have a tool known good at curing that infestation, or at least a flightplan and log for backing up your old data so that you are not reinfected (or at least learn what to be wary of!)

Some other machine or friend will probably have to be employed to get that LiveCD going; then go into the BIOS to boot from that.

NAV 2004 and below were notorious for this likely issue. NAV would go into a loop re-writing the infected code into a temp folder as part of a detection routine gone crazy. Given enough time it could fill up your hard drive with the infected code. I quit using all Norton products as a result of this. There is a fix tho, but it involves some real work on your part. So my suggestion is to TRY to put the computer into safe mode and remove Norton. Why? Because it has become the bigger of the two problems and keeping you from solving the real issue. If you have access to another computer on the internet, download Avast Home 4.7 ( www.avast.com ) and try to install this product while you are still in Safe mode on the infected computer. Get the VPS update file while you are downloading as that contains almost all the necessary updates to the main Avast program. Install the VPS updates directly after installing main program without rebooting first. That will let the updates function during the necessary scan at reboot. If for any reason you are unable to remove Norton in Safe mode, there are small routines available on the Norton website that will allow you completely remove the program as if the Un-install no longer functioned properly. These routines can sometimes be difficult to find but they are there and if necessary I can get them for you.
Whatever you do, give Avast a try, you'll be glad you did. Contact me directly if necessary at ' hantoyo1@yahoo.com ' or Yahoo Messenger ID ' hantoyo1 '

    If, as I suspect, you have the looping NAV problem, then the antivirus is far more dangerous to your system then the trojan/virii file. Depending on how long you let the computer stay powered up while the problem was occuring, NAV could have written Gigabytes of bad code to the NAV temp folder in question. This may cause loss of data, data corruption, and most assuredly loss of available disk space for other duties.

    Once you have stabilized your system, and assuming you have left the NAV folder intact ( which I wouldn't even bother trying to do knowing the history of this problem as I do ), you will still need to reclaim some of your hard drive space by removing the contents of the temp folder in question. It lies deep in the NAV subfolders of your Norton installation. All I can say is ' have fun ' and I hope you know how to use Windows Explorer extremely well.

Trojan Horse Removal


A virus is program that has malicious content in it and replicates itself and a Trojan horse is program that will only work if the user executes it. Sometimes, a Trojan horse covers itself as a fake folder while in fact, it's an .exe file.
The good thing about Trojan horse is that it is not that hard to get rid of them. But the bad thing about Trojan horse is that it is a little bit difficult to find them.
Although, it does not corrupt files or delete data stored on your hard disk until you execute it. Once executed, it will allow the hackers to indentify your credit card number, social security number, bank account details or some other private information.
You can delete or remove the hidden Trojan horse with the help of antivirus software. Either, you can also try the manual process to delete it or you can follow these steps:
STEP 1 Open the System Information Utility (msinfo32.exe). You can find the System Information Utility by typing “msinfo32.exe” in ‘Run’. This program lists all the processes running on any Windows system, even those processes that are hidden from the task list. Now open your virus scanner and run the executable or .dll through it.
STEP 2 Open your antivirus software and run a virus scan. If you don't have a antivirus software installed, download AVG Anti-Virus Free Edition 7.5. And run a scan using it. After the scanning process is completed, delete the value that was detected from the registry (before doing this step, take a backup of the registry files):
A) Click ‘Start’ > ‘Run’.
B) Type "regedit".
C) Click "OK".
D) Go to the subkey:

HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServices
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices

E) Now delete any value from the right pane that was detected during the scan process.
F) Exit the Registry Editor.

Well this Win32/mebroot is a trojan and you need a trojan killer to remove this. you can remove this by two ways -
1. Online - means when your computer runs the operating system and you can install the trojan killer and search for the trojan.

Torjan remove virus


Reboot your computer if you have a Mac. Do this by holding down the "Shift" key while the computer restarts itself.

Launch an antivirus program that you should have installed on your computer, such as Symantec's Norton or McAfee. Wait for the program's window to appear, then go to "Disk View." Highlight your computer, then select "Scan/Repair" so that the antivirus can detect the Trojan and trash it.

Exit the antivirus program on your Mac. Restart your computer again to ensure that the Trojan has been deleted. Empty the trash can on your computer once it is back up and running.

Disable the System Restore feature if you're a Windows user. Go to "Start" at the bottom of your screen, then right-click the "My Computer" icon to go to "Properties." Check "Turn off System Restore" under the System Restore tab in the "Properties" window, then select "Apply." Confirm that you want to disable System Restore by clicking "Yes" and "OK."

Update your virus definitions in your antivirus program. Open the program, or go to the website, to download the latest definitions so that you can receive the most recent alerts and keep your computer protected.
Scan your files to detect the Trojan file. Follow the instructions in your antivirus program to delete any suspicious files. You may want to write down the path and file name of the Trojan, which is usually found in the "C:\" hard drive. Then, edit your computer's backup registry by choosing "Start," then "Run." Type "regedit" in the window that appears and click "OK."

Search for the registry entry from which the Trojan derived, which may begin with "HKEY" followed by the file path. Delete the registry entry to ensure that the Trojan is removed. Exit the registry entry, and restart your computer so that the changes can take effect.
Hopefully, it may help to remove Trojan virus from your PC.

Restart your computer, and keep pressing F8, until you get the Windows "start-up" menu -- white text over a black background.
Choose "Safe Mode", and see if you can logon.

Then, try one (or more) of the anti-virus scanners listed at:

Or, follow the "best practises" recommended by Microsoft:

and backup your data files, reinstall Windows & your anti-virus software,
and reload your data files.

you need to press F8 while the pc is booting for a startup in safe mode, then when in safe mode select start windows in safe mode, go to my computer, properties>system restore tab and turn off system restore and then run the scan again as these trojans cannot be deleted when the pc is in normal use.

 

If your antivirus finds them but cannot heal, make a note of the file that has the trojan and then search for the file and delete it manually.

 

Ensure after the trojans are deleted that you tuirn system restore back on
