Every time I open my computer I have an error message about dll error.khffcyax.dll, pvecyisr.dll. How to get rid of this error? Please help.
A .dll is a file extension that stands for Dynamic Link Library file and is a part of a computer’s operating system. These kinds of files have code that contains functions for another executable code.
.dll Errors
.dll errors can be caused by many things, although in your case I suspect a virus or Trojan. They can be cause by a program that uninstalled a .dll file that another program or the operating system needs, a bad installation or even a hardware problem. Have you uninstalled or reinstalled any programs lately? This could be a cause.
Manually Download .dll Files
If you can find information on your particular .dll error, then you can try to download the .dll manually. There are many sites on the Internet where you can look for a .dll file and download it from that site onto your system. I could not find any information about these two particular .dll errors, which tells me that they are most likely caused by a virus.
Run Antivirus Programs
It sounds to me like you can still access your system, even with these .dll errors popping up. If you can get into your computer, then the first thing you need to do is run a good antivirus program, as well as a good antimalware program. It is always advised to run more than one to catch the most errors possible. If you don’t have a good program installed, or want to try a different one, look to our Filetonic antivirus reviews article for suggestions. Once you have thoroughly checked your system, the .dll errors may disappear.
If you are running Windows XP, there is a program built in that can scan the system for these errors. Go to Start and then Run. At the prompt, type in sfc /scannow and click Enter. This may allow the system to fix the .dll errors by itself.
System Restore
If these methods are still leaving you with .dll popup errors, you can try a System Restore to bring your computer back to a point before these .dll errors were happening.
- Go to Start and then choose All Programs. Select Accessories.
- Get into System Tools. Then choose System Restore.
- You will see a Welcome Screen. Find “Restore my computer to an earlier time” and choose it.
- Click Next. You will be asked to choose a restore date. Pick a time just before the problem started to happen to your system.
- You will need to confirm the date and the system will shut down and reboot.
Start with updating your virus protection, and go from there. One of these methods should get rid of those annoying .dll popup errors.
