Welcome to the Virus Encyclopedia of Panda Security.
QHost.IP is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level.
QHost.IP prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).
QHost.IP uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
