This is probably the easiest way to fix a rundll32 bad image error and the least
dangerous overall when you're trying to repair a system as intricate as windows. Keep in mind the fact that though anti-virus software is great at ridding your pc of dangerous files, they don't fix the confusion that viruses tend to bring about in your registry files. I'll expand on this a bit: this fixing software won't eliminate malware, for example; for that you'll need another utility that was specifically designed for that purpose. Avoid computer hassles by remembering that your pc is no different from your car as it needs looking after to make sure it remains running and reliable. A last note - perhaps you know other pc users who are struggling with errors - why not share your new knowledge with them; i'm sure they will thank you for that.
