I have a Windows 8.1 Computer with Internet Explorer 10. When I turn on the Computer I get a prompt that asks if I want to use net command I check Yes- I cant figure out what is causing that prompt? Then when I click on the Internet explorer icon, IE executes and stays on my desktop for about 1 second and then it closes? The only way I can get IE to run is to right click on the icon and then click Run as Adminitsrator. Then the program works fine. I have run all sorts of anti virus tools and I updated my Antivirus ( Bitdefender)- finds nothing. I ran dozens of Malware programs like Malwarebytes, unhackme and other- finds nothing. I have ran most tools you have posted in this forumn.Anyone got any ideas on these problems? I can not re-install Windows 8.1 as when I bought this machine, they do not give any disc anymore and you have to buy the Windows 8 program again. Maybe someone know of a "fix it" program that I could run?
