Windows installer and

i’m sorry to ask this on kirupa-forum, but i’m still…

i’ve this stupid ad on my comp. it opens itself with some links. it did open before, too. but now windows installer pops up before and then does something. it’s like a little screen with some message, a progressbar, and cancel button. i click cancel. windows installer pops up 3 more times, and i click cancel 3 more times, and then ad pops up.
how do i remove that windows installer… i’m trying to remove :nervous:
