And I frequently left it connected.

Well, it seemed very strong at the time.  I remember seeing several 
messages alerting me to attempted intrusions from the web, as well as 
from within.

Windows *IS* and infestation.

It would reduce security?

I just placed a one dollar bill on my desk, and next to it I placed a 
hundred dollar bill. What’s the difference between the two bills? Both 
bills are composed of the same thing – linen and cotton. So what’s the 
difference. The difference is the writing on the two bills. Both say 
they are legal tender ‘ for the payment of all debt, public and 
private.’ The only real difference between the two items is that the 
Treasury states that one will pay off a dollar of debt while the other 
will pay off a hundred dollars of debt. Thus, this nation’s money has 
been degraded to the point where the writing on a piece of paper tells 
you what the thing is worth. This is money by government edict or by 
fiat. Intrinsically, neither bill is worth a damn thing. And ultimately, 
they’ll both end up as bookmarks or museum pieces.
