My AV software also blocked one of the downloads....however another "bug" from this attack managed to cling to my temporary internet files.
It appears the initial trojan attempted to direct your browser to another site where it tried to download another bug onto your computer.  It was the second download that was blocked.

So...to make a long story short...it is best to do a full virus scan to make sure some of the "critters" haven't made their home in your computer.

In youth, we learn....with age, we understand.
