Hello. I am using Kaspersky Internet Security Trial version. My Antivirus showed Scan Advanced Disinfection. So I clicked on it and then it started. But even after 1 hour of starting the scan, it is still stuck on 1% and 0 files scanned. I tried to stop it but there is no button to stop. I tried to restart my laptop by clicking start menu but the restart button is disabled. I tried to open internet explorer and any other program but none is opening. When I try to open any other program, it says "Windows cannot access the specified device, path, or file. you may not have the appropriate permission to access the item." Then I tried restarting my laptop but pressing power button. It restarted but while restarting, it showed "Resuming Windows" And then same picture of 1% stucked scanning on my laptop. I am not even able to shut down the laptop. When I try to open task manager, it also says "Windows cannot access the specified device, path, or file. you may not have the appropriate permission to access the item." Please help. Thank you.
