Welcome to the Virus Encyclopedia of Panda Security.
QAZ is a dangerous trojan that opens many communication ports and sends out the IP address of the computer via e-mail.
By doing this, the computer becomes vulnerable to hacker attacks.
The file that carries out the infection (NOTEPAD.EXE) can reach computers through any of the usual means used by viruses: Internet downloads, e-mail messages with infected attachments, FTP, etc. However, QAZ can also spread through mapped or unmapped network drives.
QAZ is difficult to identify, as it does not display any messages or warnings indicating that it has infected a computer.
