when i click a genuine site, avast blocks this with html.script.inf. when i browse the firefox history, the exact site is not known, but the message ends in firefox.exe, which is shown as script.inf. I am using the latest firefox with all necessary updates. I have written to avast and to the site, excelforum and awaiting replies. What that firefox exe means? what is that script. How to stop this.When i browse, firefox alerts, if i want to leave that page, and sometimes, a script is being written, do you want to continue or stop. Why this behaviour
