Hi, I'm having trouble installing some things on my computer. I first noticed the problem when I was unable to open my Norton 360. When I clicked on it nothing happened. I deleted it and tried to reinstall it and I got the error message "c:\windows\system32\d3d10_1core.dll is either not designed to run on windows or it contains an error." This same message also comes up when I try to install other things such as Flash updates. Since I couldn't use my Norton I installed AVG 2013 Free version with no problems and I scanned my entire computer. It said that I had a trojan and it deleted it. I have also used Malwarebytes, CCleaner, and RegZooka to check for issues on my PC. At this point everything is coming back clean, but this error message still comes up if I try to install certain things. I use an ASUS K50IJ and I never made my recovery dvd through AI Recovery because one was given with the laptop, but I couldn't find the disk. I went to make the recovery disk and once again I was unable to complete this task (I've since found the recovery disk). My laptop is working on the surface, but when I try to make some important changes this error message shows up. When I follow the file path I see that the file is in the system32 folder, but maybe it is a fake one and the real one was replaced by this virus. Should I delete it? How do I fix this? I've read other posts, but its hard to pin point how it applies to my issues.
