Rundll errors can originate from a number of sources including viruses, buggy software, spyware, or drive errors. A faulty installation, one that has not been completed or did not install properly, can also be at the root of the problem. Moreover, an uninstall of a program that has been performed incorrectly or incompletely may also be the cause of rundll errors. Additionally, undetected spyware may be responsible for the rundll errors occurring on your computer.
A rundll32 error is often caused when Windows attempts to load a file but is unable to do so. A message indicating that a rundll error has occurred usually appears on the computer screen. Whenever Windows cannot load a file because it cannot locate it, a rundll error has occurred.
In order to solve the problem, it is often necessary to go through a series of possible solutions or fixes to the problem. The first and most basic step is to do a simple reboot of your computer. If this does not seem to solve the problem, continue to the next possible fix.
If the rundll error has occurred because of a faulty uninstall, the next thing to do is to completely redo the uninstall. How do you know if this is the problem? Actually, you don't, but you can consider it, if you recently attempted to uninstall a program. To uninstall the program again, you will first need to reinstall it. Now, carefully perform a new uninstall of the program. If this solves the problem, you are in the clear. If not, continue troubleshooting.
If you have an up to date anti-spyware application, run it now. Since spyware, adware, and malware are constantly evolving into newer and more insidious versions, it is extremely important to maintain a current version. If the rundll errors continue to occur, attempt to do a clean boot.
