My antivirus detected rootkit virus. I tried using the AVG software to remove. I've lost my desktop and startmenu after rebooting. I am running Win XP with SP3. I've booted to safe mode and I still can't see my desktop and startmenu. I am able to navigate through ctrl+alt+del task manager -new task. I can't run explorer from taskmanager, it gives me error. Can someone please help me
