Cannot Download RKILL on a Clean Computer

My brother's computer got the Paladin virus. He asked me to download Rkill for him. I am running 64bit windows Vista service pack 2. I cannot download Rkill with Firefox, I get a "File Not Found" error. When I use IE it launches the save dialogue, then after I choose a save location it says "Destination Folder Access Denied : you need permission to access this folder" I am logged in as the Administrator and have Ownership and Full Usage permissions for the Folder in question. I have tried saving the file to several other locations including directly to a Thumb drive but it will not save. I have also tried saving several of the renamed files and none of them will save. To test I downloaded a file from C Net and it downloaded into the same folder just fine. Any help with this issue would be good as would alternative measures to Kill the needed apps manually if possible

Is this where you tried downloading it from?
http://download.bleepingcomputer.com/grinler/rkill.pif

Yes, I tried that one and several of the others .scr, .com, .exe, and a couple that weren't named rkill at all. All of the download links were http://download.bleepingcomputer.com/grinler/ and then the file name.

Have you tried safe mode w/networking?

My computer isn't infected... His is. I cannot download the program to My computer. I have not tried safe mode on my computer, I will try it if you think it will work.

Do you have any anti-malware tools that prevent scripting and what not?

Try downloading from this mirror:
