And clear your temporary internet files.
how do i do this??
thanks for the replys guys i am running AVG is this one ok??
AVG is fine, you should be ok with this but you should get spybot and adaware anyway.
To empty the temp internet files, right click on the internet explorer icon, go to properties, and on the window that opens, there is a section in the middle for temp internet files, just click delete files.
Dont hit delete cookies though as it will remove all saved log ins etc etc, not the end of the world if you do, but you'll have to sign in again on forums etc

I'm sure you'll be ok
