Please be sure not to install any software or use any removal/scanning tools exept those that you are instructed to by the expert who will be assisting you as doing so can make their job much more difficult. I hope I was helpful. Good luck and safe surfing.
Thanks for your information. Here's update. I download Anti-Malware and installed. Run the app and scan. There is only 2 registry changed or corrupted I clicked on remove and reboot pc. I open IE7 and check that blank window appears again or not. Starting the IE7 looks like that its newly installed. This time no blank window appears again and again. I check whole day to surfing here and there but no blank popup window appears.
