Hi MikeBCda,
Did not you notice that software updater came to the avast av solution?
Second rule uninstall all the software that you do not use on a daily basis,
less worries that way!
Some need java for applications they cannot go without,
Only allow it when it is absolutely needed in the browser on a on-demand basis, do not run it!
because in the browser it is that java could be abused.
Again the use of NoScript and Request Policy will certainly deminish the threat (redirects).
