ok.. you can do things like listend above like run spy ware ad-aware removal programs like
spy bot search and destroy. Ad-aware i'd say uses spy bot cuase it has something caused immunizations read about those...
. Or you can go to start---> run ... type
msconfig
and go to

www.sysinfo.org/startuplist.php

and uses this site to find out what all the things are in your start up list and remove the ones that are not need

then run a program called hijack this from
http://www.merijn.org/files/hijackthis.zip

that will remove the enties of the program right off the system mostly..... ya if that does not work... look at your process list and find out what the name of the spy ware and ad-aware is and find out on the net how to remove just it..
search some paracite remove pages and such

I don't know much but hey i hope that helps.. i am a new bie.. so people don't rip me apart.. I hate how some people on here can be so ignorant and stupid.
o yes and some of us.. are not amazing smart nerds like all of you and can't spell perfect either.

i hope the world someday can have more people as perfect as some of u//...
