I am running windows 10 home 64bit, i had macafee installed before as it had come with the computer for a short time and had serious problems with it slowing down and giving me unstable internet and then had more problems removing it, I had to disable the services basically following the steps here: http://www.wikihow.com/Uninstall-McAfee-Security-Center and then run the mcpr.exe. I had tried the basic uninstall processes and removing it from programs etc and kept running into problems but following the steps at wikihow I did finally manage to remove it. Once I finally got rid of it the computer sped up incredibly and I have had no issues since until I tried to install avast. (I don’t like not having a virus program and have used avast in the past with no problems, I’m sure there wont be any in the future but i just cannot get it to install) Other program installs and updates seem to have no problems whatsoever. I have no other security programs installed that I am aware of or can find, this is a fairly new laptop only a little more than a couple months old. I will try running mcrp.exe in safe mode, reboot and then try running rate in safe mode as well (disconnected from the internet) and then try again the install of avast. Hope it works this time, thanks again for the help.
