Hello Leonard, sorry to know this. AVG protection typically doesn't slow down the computer.Do you have some other anti-virus, anti-spyware or firewall application in your computer? If you have not uninstalled other security softwares along with AVG it can slow down your computer and cause other problems as well. Thank you.
Why did my Computer slow down to ten minutes or so to do anything
with Norton I didn't have a problem

Leonard, Before installing AVG did you download & run the Norton total removal tool (https://support.norton.com/sp/en/uk/home/current/solutions/kb20080710133834EN_EndUserProfile_en_us)?.
