F-Secure, a finnish security company recently found a malware which installs itself to almost all operating systems. It is a web exploit which recognizes the OS of the visitor and then installs the corresponding malicious code for that OS. This one is not installed on your system unless you approve a Java applet installation. In all operating systems the code does the same thing, it connects to a command and control server (with IP 186.87.69.249) and then it downloads additional code to execute. The name of this scary but intelligent malware is GetShell.A. There are millions of malware out there and you can’t be too careful.
Malware for all systems
