Ok, I have windows xp home EDITION and use the latest version of internet explorer.  I am not having any trouble with the computer itself, seeing I shouldn't because I just got it a few months back, but everytime I'm on the internet, sometimes 3 or more times, this box pops up that says
Notice: If your computer has errors in the registry database or file system, it COULD cause unpredictable or eratic behavior.....and then goes on to ask me if i want to install winfixer 2005 to check my computer for free...

There are 2 choices.  Ok, or Cancel...I always say cancel or hit the red x to close it.  But..it doesn't listen and tries to anyway.  I have wireless internet in my room that pulls off the internet in the living room.  

It's aggrovating because i can't get it to leave me alone...i have the pop up blocker set to high, which blocks most other ones, but this thing just won't stop popping up.  Then sometimes when i get through the process of trying to close it, whatever window i have open will close too, then like 10 min. later, it pops up again!!!!

HELP!Try Ewido in safe mode with system restore turned off.This isn't just a simple pop-up. It is something much worse. Maybe Blackberry can test it out for us....what is Ewido?
