Hi Ambucias thanks for sharing your ideas, yes I already did deleting temporary files and cookies, but still the same issue. I even tried configuring "host" which is deleting columns that is mentioning www.facebook.com (although when I configured hosts, by opening it through notepad, there's no facebook whatsoever), I tried uninstall all web browsers and re-installed google chrome, the issue was fixed for 1 day and the next day it occurs again. I also tried to put "s" on http (https://) and still it didn't solved the problems. I'm so helpless now, I can only chat with my parents when I am at work.
---- still waiting for other solution. thanks!
