Vista - Spy Sweeper Blocking Game Installation

I recently had my hard drive replaced. Previous to that, I was able to
download my
Big Fish games with no problems. Now when I attempt to download any of my
games from Game Fish, a Spy Sweeper message pops up with "File System Shield
has quarantined a potential threat that was trying to install itself."

I am not real versed in this sort of thing, but I did try to go into the Spy
Sweeper program and check off some of the files such as BFservices, BFclient,
etc. and see if that would work but to no avail.

I did contact BF and they stated that they had tried recently to get BF to
stop blocking their site but they have had no luck. Not sure if that is true
or not. Thing is, I didn't have any problems before I had the hard drive
replaced.

Does somone know what I need to do to remedy my problem. I appreciate any
input anyone has...Thanks in advance.
