download the latest spybot search n destroy, dont rely on an older version to update itself. when u get the newer version u get the tea timer update which stops them before they even get a chance.
If u wanted to remove it easily as noted above get Hijackthis.
Alternatively ditch windows altogether for email and surfing
keep it for gaming etc.. but,
get a mac or use a linux box for the majority of web and email.
stop using IE, theres so many exploits now it aint funny.
If no-one gives your an answer to a question you have asked, consider:- Is your question clear.- Did you ask nicely.- Are you showing any effort to solve the problem yourself
