.co.uk sites blocked...(malware related)

[HMSSHM]

Hello all,
On my PC, all .co.uk sites are blocked and instead land on some advertisement sites.
Can anybody explain/suggest what is wrong with my PC and how can I fix that?

what browser are you using and what sites are you wanting to get on?

what browser are you using and what sites are you wanting to get on?

I use firefox, but I also have netscape and internet explorer, and there's the same problems on them.
I try to get on BBC or the Guardian...
