Virus removal

[Guest]

Someone using my account accepted a file on msn and now everytime I turn on
the computer it brings me to the window where i can choose to boot windows
normally or safe mode and things like that even after i pick "boot windows
normally" or "boot windows in safe mode" it'll load for 2 seconds and restart
without even letting me get into the account logins
is there anyway i can get rid of this virus without formatting, if not then
how do I reformat with a problem like that. Thanks in advance!

boot with the install cd and try the repair option.
