Java Exploit

Java Exploit is a malicious computer infection that exploits vulnerabilities in Java programs running on Java Runtime Environment (JRE) software framework. This Java applet can infect a vulnerable program and exploit it according to hacker's wishes. Most often, Java Exploit is used to download and install malicious files onto the target system. Generally, Java programs do not have a permission to perform such actions, but Java Exploit allows the attackers to call system level Java functions, forcing it to perform actions that usually should not be allowed.

You can get infected with Java Exploit if you use Java programs that are not constantly updated. This applet exploits vulnerabilities in the JRE that are commonly found in the following Java versions: Version 5 update 33, Version 6 update 30, Version 7 update 2. In order to protect yourself from Java Exploit, you have to update your Java programs regularly, because the creators of JRE platforms are aware of the vulnerabilities within the programs, and they release software updates immediately.

You don't necessarily have to have a Java program installed to become a target of Java Exploit. Sometimes, when a website is infected with its malicious code, Java Exploit might attempt to compromise your computer when you open the said website. Then, if you have a computer security program installed on your system, the program will prompt you about the unauthorized attempt to access your system.

The Java class files that are part of Java Exploit archives include c.class, a.class, a2.class, b.class, and a1.class. When JRE is infected, a hacker can connect to your computer via remote server without your permission and the infected program can be responsible for a dangerous malware infection arriving at your system. That is so, because the files that Java Exploit downloads can also include additional malware.

The bottom line is that if you must remove Java Exploit immediately, in order to protect your computer from harm. We highly recommend removing this malicious applet automatically, because automatic removal with a powerful computer security program will ensure that your system is protected against similar infections as well. Do not hesitate to perform a full system scan with a computer security program of choice, because with Java Exploit on your computer, you are very likely to have other infections as well.
