Attached is a typical Host file. If you have used SpyBot or certain Adobe Software (CS) it will add web site addresses after the last line 127.0.0.1. localhost If you update your Host file, it will remove those lines and you won't be able to update Adobe, and you will have removed the sites that SpyBot is blocking for you. There may be other software too that updates that adds lines here.Babbzzz said:Hello spunk.funk;I think I got it wrong. I just wanted to reconfirm why I was wrong. In my head, it seemed that HOST files are a list of websites that get blocked automatically? These HOST files contain probable malicious links right? So, why not update it? Thank you.
