For that reason we have to leave it in. Fair enough, but can that individual entry be excluded from detection without excluding the entire HOSTS file? I understand if it cannot, however I'd suggest looking into it as a future feature if it can't for cases like this because malware could still hijack a user's HOSTS file when using a custom HOSTS file like this so it's important to be able to delineate undesired malicious entries from those that are deliberately being blocked by the user to protect their privacy etc.

AV proper for updating or anything. This is a per line detection. However ganging up urls on the same line will cause the whole line to be deleted.

I was simply concerned for the user and others like them who may encounter this issue now that Avast!

Can you confirm? If that works as expected, then you shouldn't need to exclude the entire HOSTS file and if something malicious modifies it, the bad modifications will still be detected.

In this article we'll cover what a hosts file is , how to edit it on Windows , and we'll go over some neat tricks you can do with it. Back in the early days of the internet, before it was widespread, computers used a hosts file to map long, hard to remember IP addresses with much shorter, easier to remember hostnames.

That way, instead of having to remember a long IP address, all you had to do was visit localhost. As the internet grew, so did the length and complexity of the hosts files. Also, each hosts file only worked for the computer it was on, and keeping them in sync with the changes in hostnames and IP addresses became a huge pain. For example, imagine that you have two computers, A and B.

Their hosts files contain this mapping for google. So everyone on computer B is stuck without Google until someone updates the hosts file. When that person does update the hosts file, they add another entry to handle Google with the www subdomain.

Now everyone on computer B is taken to the correct website whether they visit google. And everyone on computer A can only visit google. If you're thinking that someone should have just made a central repository to map all IP addresses with all hostnames, that's exactly what happened. Early on, a central hosts file was manually maintained and shared by the Stanford Research Institute. This system lead to the invention of domains and top level domains like.

In the end, the humble hosts file and innovators like Elizabeth J. Feinler lead to the invention of the Domain Name System still in use today.
