Description

Evidence of infection with the Qhosts trojan has been found on the system. This trojan installs itself by exploiting a vulnerability in Microsoft Internet Explorer when the user loads certain infected web pages.

The Qhosts trojan will change the DNS settings on the machine to point common search engine sites (Google, Yahoo, Altavista, etc.) to captive servers which then display popup advertisements for online gambling and pornography sites.
