this happens after loading the page, I already dealt with the dns, with flusing that in cmd, the ip, nothing! only solved with "thisisunsafe", sometimes it resolves itself for a while but it comes back

@sgunhouse The first thing I tried was to look for virus, Trojans, etc, the system is clean, something that was installed soon and the only thing is the update of it, and since the other browsers work well it is not the antivirus
PS: I use malwarebytes premium and w10

@dragox85 nothing new, I have the same antivirus for a while, and the problem goes from this update,
by the way i use w10 to date

My English is terrible, since the new update it is impossible for me to connect to a page, the ERR_EMPTY_RESPONSE always appears, when I can connect it appears that the page is not secure (it appears with any page), I have tried Everything , from loading the dns, flushing, reinstall opera, check my modem, the network and Nothing , it is the opera browser, the internet explores it works great and I had to install chrome because it no longer served
Sometimes the message to load this page appears, and puts the message "thisisunsafe" but that only works for one page!
Any idea what happens?
