I am getting near constant "Verify Certificate" popups on my macbook with the message "Safari can't verify the identity of the website "
www.tumri.net". When I click the Show Certificate button, is says that for
www.tumri.net, the certificate was issued by "Avast untrusted CA" and a red note that says "This certificate was signed by an unknown authority" Under "Details" it says the Country is CZ, State/Province is Prague, Organization is AVAST.
I have not clicked Continue as I've read that tumri,net is no good. I haven't found anything recently discussing this anywhere. Does anyone have any clues what I should do about this? I can't even find relevant removal instructions for iOS. Thank you for any input you have on this.
