Problems starting the windows

Hello,

I installed the avast in my pc and i run the program. It said to me to run the boot scan, so that was what i did. After it made the boot scan (and it put a lot of files into quarentine) i reboot the pc and now i turn on the pc and i just can see the backgroun image. What can i do to start the windows correctly. WindowsXP

Can you boot in SafeMode (repeatedly press F8 while booting)?

If so, better will be trying to start avast Chest again and post the name and file of the infected files.
If you do not succeed on booting, well, post again and will try plan B.

Have (or did) you have another AV installed in this system, if so what and how did you get rid of it ?
This could have this type of conflict on boot after the scan.

Crtl + Alt + Delete then go to File > New Process and type “explorer.exe”. I had this problem too.

Thak you all for help.
First i can boot in safe mode but after i had chosen the option safe mode the pc start the safe mode but nothing happen. Second i don’t have any other av installed. Third after i started the pc and when comes the part that i just can see the background, i press ctrl + alt + Delete and nothing happens.
One more time thank you the help.

I’ll post the same as here… http://forum.avast.com/index.php?topic=24287.msg199410#msg199410 :-\ :cry:
