Help - I think I have caught something
 

Whilst googling I lately, appear to being connected to random "search" sites when I click on the site I actually require. I run Ad aware SE and avast anti-virus as well as a fire wall. Any of you experts out there got any ideas? :mad:

Depends what web pages you are logging into.
If it's a personal page for example, the owner may not pay the renewal fee for the domain. When you try to view the page, the domain could be up for sale again and the ISP will often include "Search for..." frames.

Or, you could have spyware/virus
