With your other topic about enb and now this I suspect you have viruses on your computer. I have been working on computers for a long time now and these are the kinds of things that will come up when you have viruses. I think you should either try scanning your computer from safemode or try an online virus scanner like http://housecall.trendmicro.com/ which I have used successfully to get rid of viruses. Don't use the virus scanner you currently use in normal windows since that is one of the first thing viruses attack and compromise.
