Hi Have used avast for years, and just updated to new version , now my computer lags out when i use it. I have uninstalled by starting up off a boot disk, then going back and cleaning out the remains. Have tried three time, computer runs great no avast, lags out when avast is installed. I have two other machines that i run on the paid form of avast, they are due for repayment in days, now i'm worried that avast will lag those out too. Heeelllppp
