exeHelper works like Rkill and you can download two format:
Also, please use the guide in http://www.bleepingcomputer.com/virus-removal/remove-malware-defense
There's a method to do before using Rkill. If you've done that, see below:
See if exeHelper will run or if the guide will help. If not, I suggest posting your log in http://www.bleepingcomputer.com/forums/forum22.html
Please mention to them the tools you've tried, including Rkill.
Hi. I have Windows Vista and am trying to run rkill because I have Malware Defense. I had Internet Security 2010 as well, but I was forced to do a system restore and that went away (I think). When running Windows normally, it would not let me run any version of rkill because it said, "pev.exe has stopped working, windows will try find a solution" etc. I have tried all four. I thought I would try to run it in safe mode, but now the black screen will pop up and then immediately disappear. Can I run the mbam program without doing rkill first? Or is there another way to run rkill? I don't know if these things are also important, but I have also tried the "exterminate" from the PC Pitstop program, and it will not run either. Also, whenever I log in it says, "Windows Defender User Interface has stopped working" and at one point I got a message that said "MSASCui.exe failed to initiate (0x80000003)" Thanks for the help in advance!
