I had a funny problem for the past few weeks on my work computer and laptop - websites like techradar.com, almoprav.com, sportnet.hr, sportbc.ba SOMETIMES wouldn't load and sometimes they would load just fine...
When I would check those sites on my phones (Samsung and iPhone) and iPad, the sites would always load well.
I instantly thought DNS or browser, but no...
It was my beloved Avast antivirus!
As soon as I would switch it off, sites would start loading.
As soon as I would switch it on, sites would stop loading.
Funnily enough, this would only happen sometimes.
It would be interesting to find out why Avast is blocking those sites only sometimes, but that's a story for another time...
