Java is the name for a bundle of related programs, or platform, from Sun Microsystems that allows users to run and develop programs written in the Java programming language.
In some rare cases, a few infected files and archives with infected files are detected inside Java cache folder. For instructions on dealing with such an infection, see:
The platform is not processor or operating system specific. An execution engine, called a virtual machine, and a compiler with a set of standard libraries are implemented for various hardware and operating systems so that Java programs can run identically on all of them.
Malware detections with "Java" or "java" in the detection name run on this platform when executed.
