ESET smart security is my security program, and it manages my firewall. I have used this program for a year now, without any problems. Also i did not change anything in the settings. I just switched off the firewall to try if it makes any difference, but unfortunately, no, no difference
If i run the tripadvisor website through a proxy, it loads normal. But then i can not log in, or do other things (don't know if that is normal when working through a proxy).
Perhaps it would help if, at internet options, i would 'restore advanced settings'? I am just a bit reluctant to do that, as i can't remember if i changed anything there the last 2 years. Or would this not make any difference?
