On the last 3 days, suddenly every site I try to load doesn’t work and appears this “ERR_NAME_RESOLUTION_FAILED”. It’s not my web connection because every other browser I try works!! I tried delete cookies and nothing changed, I run Anti-Malware (Malwarebytes) and nothing changed! After a few hours it works again but I can’t wait for it to do it, I have to find a solution!
Can you please help me? I never had problems with Comodo and now I had a lot in only 2 months, I’m getting sick of it, if you can’t help me I’ll change browser!

Click the menu button (three horizontal lines in the upper right corner) and click “Settings” then look at the bottom of the page and click “Show advanced settings…” then under “Privacy” look for “Enable malware domain filtering (Comodo Secure DNS)” and deselect it. Done.
