I just recieved my 4600 and I am pleased so far. I downloaded a program called Imesh to download music and thats about the time I heard of spyware. I am starting to get popups from all over the place. So I went to Imesh.com

and found out about a program called GAIN that the site uses and people were calling this EVIL. Should I be concerned or download any programs to solve whatever problems(if any besided the annoyance)that  may be caused by this.

I also heard that the computer will run faster if a spyware killer is in action?? Any truth to this, I appreciate any input on this subject!
