Anytime I try to open an exe file, it either says Rundll32.exe application not found, or an "open with" window comes up asking which program should I use to open this file. My problem is similar, if not identical to this problem.. http://www.geekstogo...th-t270699.html but my sister's computer uses Windows Vista rather than Windows XP. Can someone link me to an "exefix" for windows vista?? Thanks in advance for the help!

I have also tried this, and it does not work.... any other suggestions? I actually tried this again, but the coding was incorrect or something. It says "The specified file is not a registry script. You can only import binary registry files from within the registry editor." However, the fix that was similar to this that I tried got farther but also did not work

Cannot Import "file location" Not all data was successfully written to the registry. Some keys are open by the system or other processes.

Try this .reg also. If it does not work - I suggest you start a thread in the malware section as you may have an infection

There is no av.exe running. Although, now I am startink tothink she has a virus or a virus has eaten her computer alive. She told me she had already ran superantispyware, so I didnt think to do that. But as I was trying the last option, I ran SuperAntiSpyware and it found a trojan/rootkit. I removed it, and am now getting more errors upon windows startup, including the one about rundll34 application not found

I suggest that you start a new topic in the Malware Removal and Spyware Removal area.

Before you start a new topic click on this link --> Malware and Spyware Cleaning Guide, Please read before starting a new topic. This will give you a few preparations to make, as well as instruction for posting your OTListIt2 log.

If you are still having problems after being given a clean bill of health from the malware expert, then please return to THIS thread and we will pursue other options to help you solve your current problem(s).

I actually figured it out. I'm not sure which did it, but I booted into safe mode with networking, ran the program CCleaner and then tried applying the exefix for XP. Changed the settings under Internet options > Connections > LAN Settings, then rebooted, and it was working fine. While all this was happening, I ran another SuperAntiSpyware Scan on it and it indeed found more objects. Either way, after much debacle, I have finally fixed the problem. Thanks for all the help guys!

This problem might be caused due to improper malware removal.
System Restore might help.

Good news :)

System Restore might help.

System Restore will NOT remove an infection.

That is not valid advice, and you're not currently approved to give malware advice. If an infection was removed improperly or incompletely, then the Malware Forum would be the best place to determine that and provide additional help.

well just what exactly is "improper malware removal" anyway? If I have a program that scans for spyware/malware, and then removes it, I don't think there would be any way for it to be improper.
