Firewall may not be a wall anymore

According to New Windows attack can kill firewall, this may be the greatest threat to our computers. That is to say, we lost in the battle and we cannot rely on those experts who succeeded to charge us only.

We may not know whether this is the problem of the firewall or the Windows XP, but we must know that we have to do something to avoid being hurt again with this new threat.

Someone had asked me what was the best way to avoid virus. I suggested having a single computer for online purpose without any data and without links to other computers. If anything happened, just to clear this computer and re-install the Windows. It seems that we have to go this way in the coming future.
