i had a longer reply written earlier but lost it :( 

this really sounds like you have an ""injecter""
infestation... in other words, an addon or ""helper""
that has gotten in with or without your knowledge...

to KIS, lookup hijackthis and drop by one of the numerous sites that offer
diags for hijackthis... i /think/ bleepingcomputer.com is one of those...
check them out... sign up for a free account and post your hijackthis logs
following their instructions and those of the individual that chooses to
assist you... they will likely have you download other cleanup tools and
they will give you specific instructions to follow... do not deviate!
follow them exactly... in all instances that i have followed (not
participated in!) the infestation has been cleared... they may or may not
tell you exactly what the problem was but they do get the shite cleared off
;) 

i don't know if they still support XP systems... i think i understand that
that is what you are (still) running... the sole remaining winwhatever box
we have here is my personal laptop running vista and when the OS on it
dumps, it will be joining the rest of our boxen running one of the (k)buntu
LTS versions...
