PS.MPC is a virus that spreads to other computers by copying its code to other files or programs.
PS.MPC prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).
PS.MPC redirects attempts to access web pages of certain banks to spoofed pages, with the aim of logging information entered by the user in these pages.
PS.MPC redirects attempts to access several web pages to a specific IP address.
PS.MPC does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
PS.MPC uses the following infection strategies:
- Resident: once it has been run, the virus goes memory resident and stops functions belonging to the operating system. Therefore, every time the operating system or an application tries to access any of these functions, the virus will activate and infect new files.
- Encrypted: it encrypts its code in order to make it difficult to detect. In order to carry out its infection, the virus decrypts itself and, once infection has been carried out, it encrypts itself again.
