Thank you Exile, the issue was resolved,
i disabled Avast! and was able to install and run MwB and Adwcleaner. The result was 12 PuP's. I reverted back to WindowsFirewall as a default and reverted UAC from always notify back to default as well.
the screen flicker is gone along with the delayed typing . I'm defiantly going to switch to MwB Premium in January when my avast runs out
I placed this same question on the avast forums and got no response or solution after 3 days so im thankful for the speedy reply
