I use Mozilla Firefox as a browser, and get hardly any spam at all. The spam I do get is usually from a site I've visited, which indicates interest, so.... It also seriously limits those annoying popups.

According to computer geeks, IE also has such huge security holes that one said 'you could run a herd of elephants through them' -- and he's one of the ones that MS sends their programs to for review. Even back when MS Vista was still called Longhorn, he warned against it. And he was right.
Would you turn that thing down? I'm controlling a mind here! Look ... look at the tiny ad ...
