Then I saw that there was some malware called feed helperbar appeared on my website each time I try to re-open my browser.
Surprisingly, I can connect to every website with other devices (Ipad, my phone) under the same wifi network. All the other websites gave an error 'Err Connection refused'. Precisely, with all browsers such as Chrome, Safari and Firefox, I cannot access to most of websites except Gmail, Youtube, Facebook, etc.
Yesterday, I suddenly came across a website connection problem with my MACBook Pro. I am facing a severe problem of internet browser.
