I downloaded and opened and Adobe file today. And then i updated spybot then scanned and found nothing.
But when i scanned with Avg it said
Avg 7.5 detected a Host Change In C:windows\system32\drivers\etc\hosts but thats all.
I dont know if the spybot update or if this file i downloaded today caused it, and im very worried. I have a HJT log but im not sure if its a virus yet. What do you suggest me too.
Also so far my computer hasn't been acting weird, but its good to be safe.

AVG does not change your HOSTS file but it will alert you that it has changed since the last scan. Although malware can be responsible for altering the HOSTS file in an attempt to redirect your browser, it does not do so without infecting other areas of your system. There are several legitimate security programs like SpySweeper and Spybot S&D which can add numerous entries to the HOSTS file and that action may be detected as a change. If you downloaded and used a custom HOSTS file or made edits that too would trigger a change detection. If you did not make any changes or do not have security programs with these features, then you need to investigate what the changes are.

The HOSTS file should not show as changed unless the user is aware of a program needing a change made to it and is aware that it is being altered. Protection softwares and also Malware's will often change this file so they can affect where a computer goes to on the internet.

This is one reason why the user on this system needs to look at the file to make certain that something didn't change it and if so determine if it is a good or bad change...

General system maintenance can change the file even when it isn't apparent by visual inspection. AVG uses a checksum to compare a file before and after and a minor change or correction to the file could have caused it to appear changed.
