There are many malware and virus removing softwares and many of them are really good in removing malwares. One of them is Norton Power Eraser. Some of the malwares don’t get removed even after trying out various antimalware softwares. Norton Power Eraser is a tool which has shown great results with even most stubborn malwares.

It is quite powerful and is known to remove most of the malwares. It is also mentioned on norton’s site that this should be used as last option before you format your hard disk to get rid of the virus.

Because the Norton Power Eraser uses aggressive methods to detect these threats, there is a risk that it can select some legitimate programs for removal. You should use this tool very carefully, and only after you have exhausted other options.

Download the software from the link given at the end of post.Installation takes minimum of time.

Now scan your system with the scan option in the interface.

The result  of the scan appears in a list format. The malwares, virus are shown there but other non threatening programs may be listed as well. Now, you have to be careful before deleting the threat. If you do not know the function of the mention malware in the list, look it up on the net before deciding to delete it. Thats why NPE should be the last resort.

NPE didn’t find any threats in my system, so I can’t snapshots of further steps. So I’ll just mention them.

NPE will create a restore point just in case you want to restore back to older settings if you delete an important program. Now restart your system for the changes to takes effect.

NPE is a useful tool to keep and try when you are troubled by a virus which seems to be unremovable.

Autorun.inf is the primary instruction file associated with the Autorun function. Autorun.inf itself is a simple text-based configuration file that tells the operating system which executable to start, which icon to use, and which additional menu commands to make available. In other words, autorun.inf tells Windows how to deal open the presentation and treat the contents of the CD.

But in some rare cases autorun.inf files are also created by malware. Few malwares create their autorun files and if present in CD or pen drive, they infect the system to which it is connected. Most of the antivirus do not really help to get rid of such malware autorun files.

To remove this virus there are more than one ways to do so. I am going to talk about two ways here to remove this virus. First is that one may use a software already designed for the purpose of removing autorun.inf from the system. Another is the manual method of removing the virus.

METHOD 1

A great software for this purpose is the Autorun Eater. It is not exactly a anti virus but a application that detects and removes the autorun virus in real time before it could be executed as autorun.inf. Some key features of autorun :

·Scan and remove suspicious autorun.inf files found in the root directory of all drives, C-Z, in real-time
· Scan priority(normal/high)
· Scan results are logged
· Add and remove from startup entry
· 3 optional registry fixes (Task Manager, Regedit & Folder options).
· Users are informed whenever a suspicious “autorun.inf” file is detected.
· Backup copies of suspicious “autorun.inf” file(s) are created before the original copy is removed for easy recovery.
· Status tooltip to get tool info easily without right-clicking on tray icon.

One of its most important option is Close Autoplay which prevents the execution of malware via the AutoPlay window.

METHOD 2

This method deals with removing the virus from the USB drive. Follow the steps below to remove the virus.

1. While the computer is still off, plugin the USB Drive.

2. Insert the Windows  CD-ROM into the CD-ROM drive. It must be the bootable Windows Installer.

3.  Start the computer from the CD-ROM drive. It will start Windows Setup screen. When the “Welcome to Setup” prompt appears.Press “R” to start the Recovery Console.

4. If asked “Which Window installation would you like to logon to” select the number. Type “1″? then Enter, if only one installation of Windows is present.

5. It will bring you to command prompt, C:\Windows>

Proceed with the following command:
- Type d: (This is the drive letter of USB. It can be e: or f: defending on how many hard disk or cd drive is installed)
- Type attrib -h -r -s autorun.inf
- Type “edit autorun.inf” it will open DOS Editor and display contents as follows

==========================
[autorun]
open=file.exe
shell\Open\Command=file.exe
shell\open\Default=1
shell\Explore\Command=file.exe
shell\Autoplay\command=file.exe
==========================
Take note on the file that it called to open (in above example it is file.exe)

6. Exit DOS Editor and return to command prompt.

7. Delete the file that was called to open on DOS Editor
- Type del /f /a file.exe

8. Delete autorun.inf file
- Type del /f /a autorun.inf

9. Exit Recovery Console by typing exit.

Use the method you think is fine for you. This should get you rid of the problem of autorun.inf
