Steps to Resolve File Extension Issues

Run a malware scan

Malware programs often corrupt applications as well as important system files by altering the codes embedded in the files. An infected file, in turn, starts behaving erratically and may refuse to open with its default program. If you are experiencing a sudden upsurge in file-related issues on your computer, then chances are your computer’s security has been compromised.

To resolve the issue, reboot Windows in Safe Mode and run a malware scan on your computer. Before you reboot Windows in Safe Mode, update your security software with the latest malware definitions to allow it to identify and take appropriate action against the latest malware.

To reboot Windows in Safe Mode, follow the following steps:

1. Close all running applications and restart your computer.


2. Press and hold the F8 key with the restarting of Windows.


3. Select the Safe Mode option, using the arrow keys in the Advanced Windows Boot Options menu, and press the Enter key.

Run a registry scan

In case the error persists, chances are that the file-association information in the registry is incorrect or incomplete. To fix the issue, restore your registry’s integrity by performing a thorough registry scan using a professional Windows registry cleaning tool.

Use a reliable file extension repair tool

In case you are still unable to open the required file or receive a ‘cannot open the requested file’ error, then chances are that the damaged file openers on your Windows system are the culprit. To fix the matter, use a reliable file extension repair tool. Such tools quickly fix damaged file openers, allowing users to open, edit, or save the required file.

Best Ways To Handle Computer Driver Errors

Best Ways To Handle Computer Driver Errors

These days there are several peripheral devices that can be attached to your computer to perform amazing functions. These peripheral devices are usually instantly recognized by the computer and will start communicating automatically. This communication is made feasible by software programs known as device drivers or simply drivers. The main reason for these drivers is to act as a medium between the computer and the peripheral device by converting the message sent by your PC into a language that the device understands. All devices including web-cams, scanners, printers, pen drives etc. require a driver.

Computer drivers can sometimes encounter problems and can lead to non-functioning of that peripheral device. Here are some of the common reasons behind driver errors:

Obsolete Drivers

If the printer driver that is installed on your computer becomes obsolete, it will cause problems. This is because outdated driver files are not able to communicate properly with the computer. An example of this kind of problem is:

“AirGCFG.exe – Entry Point Not Found. The procedure entry point apsGetInterfacecount could not be located in the dynamic link library wlanapi.dll.”

This problem occurs when you update your Windows XP PC from SP2 (service pack 2) to SP3 (service pack 3). It can be easily resolved by updating the device driver either by visiting the manufacturer’s website or simply by using automatic driver update software which can find and install the latest driver in a few minutes time.

It is a good computing practice to regularly update your device drivers in order to avoid any problems related to performance as well as compatibility. This can be done either by using the Device Manager utility or an automatic third party driver update tool.

Malware infection

Many instances have been reported where malicious software hide themselves behind genuine device driver files and use the same name to enter the system. Once inside, they cause problems. To ensure that there is no such disguised malware on your system, it is crucial that you not only have the best antimalware program installed on your computer, but also perform complete scans and keep the software updated with the latest definitions. This way you will ensure that none of the device driver files pose a security threat to your system.

Malware programs are also known to damage device drivers by corrupting their files. In such cases, it is vital that the malware is removed from the root before replacing the corrupt file with the latest version of the legitimate driver.

Start-up problems

It is recommended that only those programs that are absolutely essential to start the computer be part of the startup process. However, it is often noticed that certain non-essential application files also become part of the start-up process. These not only tend to hog computer resources unnecessarily, but they can also cause start-up errors.

One such driver file that is not essential yet makes it to the startup process is alcwzrd.exe, which is a process related to Realtek audio drivers. You can safely remove this file from your start-up list if you encounter any issues. However, if the file is essential, but you don’t need it to load it at system startup, just disable it from loading automatically from the Services management console window that you can display by running the services.msc command.

Smart Ways To Resolve DLL Errors On Your Computer

As your computer becomes older, the frequency of recurring errors increases. The most prominent of these errors are software and computer applications errors. The good news is that software and application problems are usually much easier to solve when compared to other PC errors, such as hardware issues.

One such software problem that frequently occurs in computers is DLL errors. This article explains what DLL files are and how to resolve DLL errors.

A DLL file is used by an application to perform a specific function, such as controlling dialog boxes. A DLL file can perform one or more tasks and can be used by multiple applications simultaneously to perform a specific task. The concept behind using DLL files is to simplify things and improve efficiency. Many tasks are common to different programs, such as providing the Graphical Interface that appears on your screen. It is best that programs call upon shared DLLs to perform such tasks instead of carrying codes themselves to complete such tasks.

Now that we have covered what DLL files are, let’s take a look at some examples of common DLL error messages:

“[DLL Filename] not found.”

“[DLL Filename] is missing.”

“This application failed to start. An important component: [DLL Filename] is missing. Reinstalling the application may fix the error.”

Steps to resolve DLL errors

Perform the following steps to repair common DLL errors, such as the msvcr80.dll error or faultrep.dll error.

• Run a malware scan – Malware programs, such as viruses, rootkits, and worms are not only harmful to a system’s performance, but also cause various errors, including DLL errors. Malware programs corrupt your DLL files, such as the msvcr80.dll or faultrep.dll file and cause recurring DLL errors. When you receive a DLL error message, such as one mentioned above, thefirst thing you should do is run a malware scan of your entire computer using advanced antivirus and antispyware tools. If scan results show the presence of malware programs, immediately remove them to fix the DLL error.


• Reinstall the application that is generating the DLL error – In case you are receiving the DLL error only when you try to run a particular application, uninstall and reinstall the application to fix the error.

Similarly, if you are receiving recurring DLL errors after you have uninstalled a program, reinstall the program and then uninstall it. To ensure the complete removal of a program and its associated files, processes, and registry entries, you may use a reliable uninstaller tool.

• Download the missing DLL file – In case you are receiving the same DLL error with multiple programs, verify that the DLL file is present on your computer. If the DLL is missing, download the missing DLL file from a reliable DLL Directory that offers download links to authentic DLL files.


• Perform a registry scan – If everything else fails to resolve the DLL error, chances are your registry might be the culprit. A corrupt or damaged registry causes various errors, including recurring DLL errors. To fix the issue, we recommend you run a thorough registry scan with the help of a reliable registry cleaner tool.

Easy Fixes for PC Application Errors

The most common type of application error a Windows PC user will face are DLL errors, such as wimgapi.dll, wpcap.dll, and adobelinguistic.dll errors.

The good news is that dealing with these problems is pretty easy and can be done by the user without seeking outside help. The following steps will help you resolve whatever dll errors you are facing now, and also help you prevent these errors in the future:

• Registry cleanup – Despite being the most important component of a Windows system, the registry remains largely ignored. Perhaps it is so because it spends all its time in the background and is rarely used except by the most sophisticated computer users. But as you use your computer, the registry loses its integrity; that is to say, it accumulates a lot of broken and incomplete references, which leads to system slowdowns and errors.
  
  A corrupt registry is a major cause of DLL errors and application crashes. To avoid these problems, you should purchase a good registry cleaner from a trusted vendor. After that, scanning and fixing your Windows registry can be done in a matter of minutes.


• Firewall – A firewall is a network shield that stands between your system and outside networks, working as a filter and traffic monitor. It safeguards you from any takeover hacks, and at the same time blocks malicious programs from infiltrating your computer. Therefore, a firewall is a must have as a line of defense against network attacks.
  
  
  You can get a reliable freeware firewall or you can purchase a professional-strength firewall to keep your system safe. By installing a robust firewall program, you prevent malware from entering your system and causing recurring errors, such as DLL errors.


• Anti-virus – Viruses form the most dominating problem on the Internet today. More than half of our resources (monetary and otherwise) are spent in trying to contain virus threats and damages. While there is no foolproof method against viruses, good preventative practices can go a long way in keeping your PC safe.  Always go for a professional antivirus tool even if it costs you. Moreover, keep updating it for new virus definitions and files. Regular system-scans will help you in keeping your system free from threats like boot-sector viruses and root-kits.


• Install software only from an original source – In other words, do not use pirated software. Besides being illegal, pirated software cause various errors, including DLL errors. That is why we reiterate that you should only use original software.

Most DLL errors on a Windows PC are symptoms rather than problems themselves. We encourage you to try the methods discussed above to fix and prevent DLL issues on your PC.
