Hi, I've just noticed that when I check my systems 'hosts' file it seems to be resetting itself. I'm not sure if this is been done by my anti virus software when it updates or if its happening when I start up my PC. I have windows XP and I'm running the free version of Avast. Here's what's in there each time I've been checking and this doesn't seem to ever get removed: "127.0.0.1 virustotal.com 127.0.0.1 scanner.novirusthanks.org 127.0.0.1 scanner2.novirusthanks.org 127.0.0.1 virusscan.jotti.org 127.0.0.1 virscan.org" All the extra lines I add for all the tools I've gathered from this forum seem to be getting removed. For now I have a copy of my hosts file saved with all the lines I need and I'm just mindful, now, to makesure I change it before I run any of my tools... It's getting a little annoying now though!! Please help... Thanks in advance.
