I was trying to install AntiVir PE classic to my notebook, through a CD-R,
suddenly the notebook hang half way installing. Then I switched off the
notebook manually.

But when I restarted the note book, AntiVir was already installed and
running, but the notebook repsonse was extremely slow. When I clicked the
Start button, it takes more than 5 minutes to come out the task bar. I tried
to double click the IE shortcut, it didn't response at all until 10 minutes
later. But the mouse could move freely.

Please help me urgently. Thanks in advance!
