BleepingComputer.com: Internet Explorer randomly pops up often! (virus?)

RKill is a program developed at BleepingComputer.com that was originally designed for the use in our malware removal guides. It was created so that we could have an easy to use tool that kills known processes that stop the use of our normal anti-malware applications. Simple as that. Nothing fancy. Just kill known malware processes so that anti-malware programs can do their job.

So in summary, RKill just kills processes, imports a Registry file that removes incorrect file associations, removes and backs up proxy settings, and fixes policies that stop us from using certain tools. When done, RKill will then create a log listing all processes that were terminated while the program was running. Please note that this will include processes that were terminated manually by the user as well as RKill. I have whitelisted some processes that are commonly shown as being killed even though they weren't terminated by Rkill, including the program itself, to avoid confusion that a legitimate process was terminated. Other than what is listed above, it does nothing else.
