my sisters pc had a virus a trogan horse we ran mcafee and it found 5 altogether it fixed 4 but said to restart and scan again. on restart it will not let me log back on.i tried f8 to try to go into safe mode but it will still not let me log in as administator or my log in name. i have tried all the other options in the f8 category but nothing is letting me back in.The pc is one of those mini ones and does not have a cd drive any suggestions will be greatly appreciated.

I had a similar issue last week with my sisters laptop, no password had ever been used but when I ran A2 it found some Trojans etc.

When the program started to them the PC came up with wanting a password on boot. I have a program that can remove boot passwords but running this showed there was no password just that Windows thought there was.

I put this down to malicious software & in the end after much messing around did a clean reinstall. I am of the opinion there is malicious software about that tells Windows there is a boot password when an attempt is made to remove it: However that is just my opinion.
