-What previous antivirus did you have installed before using Avast?
None, i think ive had Avast for a little over more than 2 years, earlier this year i had to register again i think.
-What Windows operating system you have? Does it have the latest Service Pack? Are all Microsoft updates installed?
Windows 7 64 bit operating system. Dont know?. Doesnt it do that automatically, my computer regularly gives me a warning at 3am about updating.
-What firewall are you using?
Windows Firewall
My computer crashed and now avast isn't working, tried uninstalling through the control panel and it wouldn't work, downloaded Avastclear and tried to run it normally and through safe made and after the "do you want his program to make changes to your computer" and i click yes it just doesn't run.
What should i do?
What was the cause of the crash 
How did you restore your computer
What error messages did you receive after you 'fixed' your computer
Not 100% sure, i had google chrome open and was starting a game in steam. got to the menu and went to grab a drink and hit the toilet. Came back to blue screen scrolling down, didnt read it quick enough before computer restarted. Asked if i wanted to start in safe mode on boot. Got a message on startup about checking recent programs i had installed and windows defender and avast had been disabled. Was able to re-enable windoes defender but when i clicked on avast it sent me to there webpage. Can't think of anything i have re-installed recently but Google Chrome has been updated. I know because when i try to go to a backup before the blue screen it won't let me because of my antivirus software.
Wouldnt say i have fixed my computer, avast seems to be the problem now. I cant open it, i cant change it, i cant re-install it and i cant uninstall it. Not sure what the problem is or how to fix it but Avast seems like the problem at the moment.
