''Lexplore'' Nightmare........

Hiya Doin',
I'm not really up on all of these new virus's and trojans and spyware etc.... I had a few on my computer which I managed to get rid of....( i think).

The latest thing to attack my computer is what i'm told is a Trojan virus, it called ''lexplore'' and it wont let me open certain pages and freezes my computer until I shut it down.

It's been on my computer for a little while now and its an absolute nightmare.
So much so i feel like getting a new computer, i'm fed up off these ba**ards sending out virus's and spyware etc.....
Plese, if you have any tips on how to get rid of this ''lexplore'' thingy, please reply. Thank you.
