» The ntdll.dll file is a file created by Microsoft that has a description of "NT Layer DLL" and is the file that contains NT kernel functions.This file is located in the c:\windows\system32 or c:\winnt\system32 directory and can also be found in the c:\i386 directory.

After your pc is infected by virus or intruded by Trojan (Worm:Win32/Dorkbot.I), the first thing comes into your mind is to remove it by an anti-virus software. But at this moment, you haven’t been aware of the side-effects of doing so. The effect of removing a virus can be as dramatic as the aftermath of a disaster. After eradicating a virus or other form of virus infection, Windows is left in a somewhat broken state. Let’s take a look at why that might be, and what you can do about it.

The most common way a malware works is where it copies files containing malicious software on to your system and then causes those files to be run by adding information to places like the registry. With that information, Windows might be instructed to automatically run the software on every reboot, or under other conditions. When cleaning your system anti-malware programs both remove the malicious files and those malicious instructions that cause the malware to run.

Another approach that malware also uses is to modify existing files. For example, malware might not copy in any additional files, but rather take an existing system file - typically an "exe" or "dll" file - and re-write it to include the malware's own code. Anti-malware programs would inevitably remove or quarantine the infected system file, which could have adverse side effects on the operation of the system. Other alternatives that people may think of include: System Restore; Recovery Partition.

The safest approach, by far, is to reinstall Windows. But given how painful that is, the alternatives that follow it are often more practical. This time, I would like to recommend DLL Suite to you. DLL Suite has three built-in features of fixing exe virus infection, sys file errors and dll file problems, and has been acclaimed by its users across the world ever since it was launched.

Download DLL Suite, install and run > Click Download DLL - Free menu > click Start Scan & Download DLL - Free button, choose your needed DLL > click More Information > click Download button from the open web page.

And Click Dashboard menu and > Click Scan DLL Errors button > Click Fix DLL Errors button after the scan. And all the problems are fixed.

If your system has been infected, your av software would have been compromised and malware would go undetected. When finished, disable av software and firewall. Retry installation.

JAMES MCCRUMMEN replied on January 6, 2013: » I have now seen a similar thread to this which doesn’t give the answer, but has been most helpful in asking questions: Mcafee is installed and my subscription is current? no anti-spyware applications; another Norton application or a McAfee application has EVER been installed on the computer; a Norton free-trial or a McAfee free-trial did not come preinstalled on the computer when i bought it. I have IE8 and run XP Pro 32bit.

  3. JONATHAN KEELING replied on January 7, 2013: » Assuming you meant that your current McAfee Total Protection subscription expires on 01 January 2013, your best bet would be taking the computer to a local, reputable and independent computer repair shop & let them deal with it. Good luck.
