J is for Java Viruses
Java viruses were supposed to be impossible. A Java ‘applet’ runs inside another application, such as Internet Explorer, under carefully restricted rules called a ‘Sandbox’. Any Java operations that may be a cause of compromising security are not allowed. However, Java can also be used to write applications with the same operations available as any other programming language and in the Java application language it is not impossible to write a virus. The first Java virus has been named ‘Strange Brew’. It has no specific payload but it contains bugs that cause it to damage the files it infects so that they no longer work properly. Now that the first virus is out we can expect other, more damaging Java viruses to be released in the months and years to come. This highlights, once again, how essential it is for a good anti-virus scanner such as Kaspersky to be installed on your PC.
