Va salut.Cand incerc sa intru in yahoo mail(logare) imi apare : "To help protect your security ,IE has blocked this website from displayng content with security certificate errors".De asemenea ,oricare site deschid imi apare sus in bar mesajul : "There is a problem with this website's security certificate".Acestea se intampla si la mozilla.Am reinstalat windows-ul si degeaba,am scanat pc-ul cu diverse programe antivirus si nu au gasit nimic.Va rog sa ma ajutati ,pe mine ma depaseste.Va multumesc anticipat .
