Hi, Everything was fine with my computer. Then I tried to install a downloaded version of spysweeper. After seeing that I needed a subscription and deleting the program I now get an error message when I start up my computer. All it says is that sv_chost.exe has encountered a problem and needs to close. Sorry for the inconvenience. I went to msconfig and unchecked everything but it still shows up. Also, when I try to run CCleaner, it says I must close IE or Firefox so it can scan it even though I have not opened it. Also, I use a version of McAfee as my antivirus software so I can't attach an AVG log or anything like that. I have attached a HiJackThis log though. Thanks to anyone who can help me.
