You can keep automated updates on, install Service Pack 2, and refuse to surf the net, but you still are unsafe from zombiefying your Windows computer.
A major flaw was reported in the Microsoft Jet Database Engine, which is used by Microsoft Office. Virus writers can exploit the weakness with an email attachment disquised as an Access file. Next thing you know (or should I say, don’t know), you are subject to outbound spam or other zombie-like performances.
With zombies already clogging ISPs networks from the inside out, I wonder how long it will be until entire companies internal networks are stopped up as a result of employees just doing their work.
Nice thing is, Microsoft has known about this for months.
