well fresh install of xp couple days ago, i spose not fully updated and it started messing about last night

takes ages to load up initially and explorer takes ages to get working

for some reason when u go to goodle and try searching for spybot etc it just redirects me, or sends me all over the place i just cant seem to get ti were i want, i managed to get the adaware last night its scanning again now as i type.

i think i foolishly clicked on a email link

what can i do?
