There is a definately a good permanent solution. Download a new browser.
IE is slow and have very limited features.
I did get a lot spywares when my gf was using IE for sometime.. now only once in a while with firefox.
With for example Mozilla Firefox (I'm using that while writing this), you can block all the pop up windows, which you do not request (by clicking a button). You can also have different tabs, which means you can have multiple pages open with only one window.
Firefox is also much lighter for you PC and therefore it will run faster and with less memory.
Best of this.. it's free.. and it's quite a popular. Well IE has the biggers share.
Come and join the GNU generation and you will repeat the mantra afterwards 
And as suggested ad-ware is good program to clean spy-wares.
