Does anyone know what best software to use to prevent my PC sending passwords to the Internet?

Of course, if the site has SSL then it's ok for sending password but let's say i visit http://www.somewebsite.com (without https://) and some how submit my personal password there.... so do we have any software that prevent doing that??? Norton Internet Security has that feature called Private Information. But since I uninstall Norton because I don't like it very much... :mad:

So any idea guys? :rolleyes:
