Hi. Pretty much the same deal as OP, except I bought 1 month of this just to try it out. It worked fine, but I am just not the kind of person that need it that badly.
But these nag screens is starting to piss me off. Uninstalling secureline didn't help, and disabling pop up for avast products didn't help either.
Surely they don't mean to scare off loyal customers by screaming "Give us money!" in their faces?
Been using avast for years, but if completely purging my computer of any avast traces, to then go to their competitor is the only way to remove the nag screen, then so be it.
