a game only can crash a pc when the pc had a problem. This apply for all games. java or not

Now there are Java applets. Applets are java programs designed to run in youre web browser. And here is the point where people say "java" is insecure. Because every local executet program could be a risk java applets are executet in a special enviroment called sandbox. This sandbox shilds youre local enviroment from the java enviroment where the applet runs in. That means for example a java applet can not access youre local file system. If the sandbox has a special bug the program can may "leave" this special enviroment and do evil things on youre computer. You see not java is the problem but the sandbox or java applets executet from any random web site.

Now simply do what Arsat said. Turn off java in youre browser. You wouldn't also never run any .exe file from any website you found.

In the hope you can understand my english i try to explain why the most people say java is insecure:

People may say java is insecure because there are viruses written in this language. But with this logic you can also say C or C++ is insecure. Of course there are "tons of viruses" written in this languages. But why exactly people say Java is insecure?

First Java is a high level language like c or c++. The special about it is that java programs are executet in a virtual machine which makes them platform independent (in theory). To this point java is as same secure as c or c++.
