Malware is replacing Google text ads with ads from another source, according to
BitDefender. The virus, Trojan.Qhost.WU, is using the host’s file to redirect the initial query sent to the Google Adsense servers to a malicious host, according to an advisory issued by the firm. The host’s file is the first step in the name/IP (Internet protocol) translation process; if an entry is located in this file, the domain name server is not queried. By supplying a false entry, the malware is able to redirect queries to a rogue server.
