I ran my daily AVG scan and it detected that I had a host problem? I toke a screenshot of it...



Incase it's important, I also ran a HijackThis scan.

AVG is alerting you that the HOSTS file has changed since the last scan. Athough malware can be responsible for alterting the HOSTS file, some security programs like SpySweeper and Spybot have features that can add entries to your HOSTS file and that action may be detected as a 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.

It is nothing to worry about unless it is reporting it as malicious.

The log looks fine also.

Hope this helps.
