I received automatic download of mcnafee with adobe flashplayer and since then probs with computer.

Ok thanks for reply. However i have tried downloading this now 6times and doest not get installed and a message comes up close skype and interenet ex. but these are closed.so something is wrong. 3rd party add ons cannot find in my comp ..only manage addons. Also flashplayer disappeared from facebook several months ago and a few weeks ago i downloaded from here and it was back again ....when i saw mcfee security i deleted it cos i didnt want that i have my own security... and like otheres have mentioned here that there was no option for ths mcfee. Then a few days ago i saw that it had been changed and mcfee could be unchecked if not wanted....that was not there about a month ago. But now as i said it wont install and getting incorrect messages saying that other programs are open when they are not. In the past we got automatic updates for these Adobe installments. When i think of how much money i have spent on Adobe soft ware Dreamweaver and photoshop .....i think this is not a good service.... so it will not install following the above instructions ...so what next?
