Armed with this you can get a clean boot and then enable item by item till you find it.
When I am booting into 8.1 and all my start-up programs are loading, a small black window pops up for just a fraction of a second. I am paranoid so I am thinking it could be a hidden remote access program. I do have team viewer but it does not load at start up. Any ideas what it could be?
Thanks in advance.
