Is there any way to stop Avast Secureline subscription renewal popup
Hi Raza and welcome to the forum. 
Are you getting this pop-up with the renewal of Avast antivirus itself or just Secureline?
What version of Avast are you using?
What product of Avast are you using?
When does your subscription expire?
-I am getting this pop-up for only secureline
-I am using 2014.9.0.20.21
-I am using avast free antivirus
-I only used Avast Secureline on trial basis which expired after 3 days but now the popup keeps on coming & I have no plan to buy a new subscription.
