program (adware, spyware, parasite).

I recently started having the exact same problem. IE will load and open
to the site's home page sometimes (other times it's fine) but if, for
example I click on a link to another page on the site or try to log on to
the site the message pops up. This happens on random sites. Hopefully
someone can shed some light on this as it is VERY frustrating
