I need to know if files that are appearing in my Windows/Temp file are spyware or not. They start with perflib_perfdata_XXX.dat. The x's can be a combination of numbers and letters. A new version of the file appears everytime I boot up the computer, and whichever is the newest one, it can't be deleted. While attempting to delete the file, I get an error message saying that Windows is using the file and that to delete it, I have to close some programs. I don't remember these files being here before. I went on Google and did a search on the file above, and I came up with a whole list of files that connected to a website, www.Chinakyl.com. I could not read it since everything is in Chinese. By the way, I started the computer in safe mode one day last week, and then I was able to delete the perfdata file, but when I restarted the computer, my display had changed (it became Windows XP modified) and another version of the file appeared again. And one more problem...every so often, I get the dialog box in the middle of the screen prompting me to connect to the internet, even though I have not initiated it. It happens when I boot up sometimes and sometimes, when the computer is idle. Is this spyware or is it nothing to worry about? I ran Microsoft's anti-spyware program, Spy-Bot, and even Norton Anti-Virus 2005, but none of them caught or suspected anything. I tried to contact Microsoft for support but it seemed to me the tech I was working with didn't know what I was talking about. I had the problem with the internet prompting before, only it was much worse than now, and I had no choice but to reinstall windows to get rid of whatever was on the hard drive. Can you help?
