My computer is not rebooting. It is due to the virus
w32/Livra A.
What can I do to disinfect the virus.
Please help

Just to clarrify.
My computer has a free evaluation copy of a anti virus
program. It detected the virus as W32/Livra.A
I thought it is disinfected. This was happened yesterday.
Today morning I couldn't roboot my computer. Its asking "
Insert bootable media in the appropriate drive"
So I guess this can be a problem of that virus. I came to
that conclusion after reading the details of that virus in
microsoft web page. But there they hasn't mentioned a
method/patch to use to recover the computer.
