Sometimes when I attempt to x out of a website a tab that says "about: blank" appears. When that occurs instead of the website closing, the page I’m on freezes and then begins to multiply into about a hundred new windows. Anyone know how I could stop this from happening? I’ve tried ad-aware but that didn’t do anything.

I was having some problems with my windows OS and i decided to do a clean install and just reformat the hardrive, but now when i try to install windows again the system files are not being copied correctly and the install freezes when it hits 81%, any ideas what could be causing this issue?
