Hi, I have been a user of the Avast browser for a couple of years.... always kept it upto date, yet recently (in the last few months) I am being plagued by this constant notification, despite following the update instructions, which all goes without any errors reported, and lasts only until I open the browser again, then it reappears.
I have totally uninstalled avast browser, using a programme that cleans all traces from the system, then installed with a fresh downloaded copy from the website, but still this persists.
