PS: I think they may have solved this now, and the pop up is not showing anymore.?
I spoke too soon, seems it is fixed on websites with Statcounter wordpress plugins, but not for websites that are using direct Statcounter html code!
Update: It now seems this has been fixed. A little strange though that a business the size of Statcounter, with millions of users, were not aware of the situation, but hopefully that has now completely eradicated the problem.
Thank you to Eset, who I have used for years, and always been pleased with their product and service, and thank you to Statcounter for being open to investigation when situations like this arise. .
