The problem started when I scanned my windows xp system with Mcafee Antivirus. After the scan completed it told me that my system is infected with backdoor Trojan. I searched for instructions on web to get rid of it and according to that I tried doing the same. Here is what I tried:
I turned off system restore, opened CMD and typed MSCONFIG. Clicked on boot.ini and set to boot in Safe Mode. After that I restarted my computer and entered safe mode.
Now here my problem started. Once I entered safe mode, computer prompted me with classic logon menu where I need to enter username and password. I entered my proper login credentials but got an error of wrong password and username. Am sure about my credentials and is correct. After 3 attempts, I thought to login with the default Administrator account. So I typed Administrator as username and left the password filed blank. But still it wont allow me to login.
After numerous trials I fed up and restarted the system to get back to normal mode. But surprisingly the system wont allow me to enter normal mode as well any more. Again rebooted the system, hit F8 to get to the boot menu and guess what, no one of these options are working now, unable to start with last know good configuration, not in Safe mode, not in Normal Mode, etc. Can you guys tell me is there any way I get into my pc ? Any help will be appreciated.
