I did widnows update of VISTA and Java-RTE update, and BINGO things started to fail.
When I launched Firefox, Site-Advisor opened an "empty-white" window and it caused the browser to freeze. Also other "direct-internet" stock-trading applications on my computer hang as soon as I would start them.
Temporary Remedy: Started Firefox in "-safe-mode", and I disabled the Site-Advisor add-on. Then, in Windows control panel uninstall I clicked on "Mcafee secur. centre" and I selected only "Site-Advisor" to uninstall. The uninstall worked fine. Now my computer works fine, but the "Site-Advisor" is completely removed from the computer. I suspect we have a McAfee bug which is interacting with Java and recent Windows Update.
I hope McAfee aknowledges the problem and provides advice as to how ro re-install only a new bug-free version of Site-Advisor, without disturbing the rest of the McAfee software on my computer. If anybody has any ideas please let us and let me know. Thanks.
