CCCleaner has had problems in the past with Macromedia Flash and it may now have a problem again with Adobe Flash Player 9 as well.
However, this is just a warning at this time and if you can get to this site you are probably OK:
http://www.broadcom.com (failing indication is that browser just sits there and says 'done'
The other suspect programs are:
Shockware Ver 10
Yahoo Security Suite
Trying to isolate this problem, I hve done a System Restore 5 times today and have narrowed the problem down to one of those 3 programs; however, I am done the "testing and breaking"; therefore, I will not reinstall any and hope I don't have to do a system restore in the near future.
The CCCleaner folks may want to do some aggressive and proactive testing on this issue because I am more than capable of resolving most problems; however, this one turned out to be my downfall with the only alternative being a system restore.
