On my Windows 7 32-bit PC, I have the latest version of Opera installed as the default browser. Every time I open the browser, I get a message from Quick Heal:
I also have Chrome installed, but this pop-up comes only when I open Opera. Apparently, Opera is trying to reach this website tudap.ru, and the attempt is being blocked by Quick Heal firewall.
I haven't added any new extension recently; all the extensions installed in Opera have been there for ages. The home page is correctly set to the Opera Start Page.
I cannot understand why Opera is trying to visit this site. Any idea?
