I was working with fiddler and came accross some weird requests that chrome was doing to some random hosts, all thouse requests always failed, apparently this is not a malware or virus, it seems that chrome does that to prevent DNS Hacking to happen and altering it’s autocompletion behaviour.

This is actually legitimate behaviour. Some ISPs improperly respond to DNS queries to non-existent domains with an A record to a page that they control, usually with advertising, as a “did you mean?” kind of thing, instead of passing NXDOMAIN as the RFC requires. To combat this, Chrome makes several HEAD requests to domains which cannot exist to check how the DNS servers resolve them. If they return A records, Chrome knows to perform a search query for the host instead of obeying the DNS record so that you are not affected by the ISPs improper behaviour.
