I tried placing an order with these guys and got this message twice.  Anyone else seen this before?  (Yes, I have plenty of money on my cc).    

That looks hokey! If it were me, I would call them directly. If all is okay with the card, I would take the computer to a computer repair shop for a professional anti virus scan(s).

I have the ability to do that from home.    Used to work with the geek squad. All is well with the computer and cc.  I will try to call them after the holiday weekend.

I ordered through them a few weeks ago and got the same error. Ended up having to pay through PayPal, but it delayed the order by quite a bit because I had to wait for the money to be removed from my pending transactions.
