Clicker.YY is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
It affects productivity, preventing tasks from being carried out:
- In the affected computer:
causes system slowdowns.
- In the local network:
it generates a large amount of network activity and consumes bandwidth.
It reduces the security level of the computer:
it changes system permissions, decreasing the security level.
It uses stealth techniques to avoid being detected by the user:
- It injects itself in running processes.
Clicker.YY 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.
