1) Disable all entries in the machine's startup list (free)
2) Use Firefox Browser (free)
3) Download & Run Spybot Search & Destroy (free) & have it fix all problems found.
There may be other and better solutions - this works for me - now and again (rarely) a window pops up from Spybot saying that a certain site is trying to modify something in my machine - should I allow or deny it?
I get no pop-ups.
Good luck...
