Can you log in to Windows at all? If not, what happens, (full error messages please)?
Can you login to Windows "Safe Mode"?
If you can do either of these then all is not lost and and you may be able to repair Windows without performing a full reinstall.

I have become a victim of a "buy security program' infection (virus)
and cannot use my Dell Inspiron E1505/6400 laptop as it has control over my harddrive.
I would like to know if the use of a re-install Vista Home disk received from Dell will allow me to format my hdd and reinstall the operating system without this embedded virus reappearing?
Has anyone encountered this type of situation? I am open to all advice.
