Researchers track the discovery of these exploits and are able to follow the progression of viruses through them. Today, they discovered vulnerability in Java (http://www.java.com/
The viruses which have been shown to spread via these backdoors are mostly variants of the Renekton virus. The Renekton virus is a program that enters via a vulnerability (more commonly known as the “FBI Scam) and then locks the user’s computer, claiming that the U.S. Department of Justice has blocked the computer on the grounds of some criminal charge, and that the user must pay a fee via prepaid card to view their computer’s contents again. The money is transferred via the card and disappears into the hacker’s pockets. A computer repair expert would be able to fix the problem, but many are intimidated by the threats.
What to do? You need to disable Java in your browser and don’t click on any suspicious links. Especially until this vulnerability is fixed, make sure all your antivirus and anti-malware programs are current and scan regularly for viruses. Don’t click on any shady links.
In order to disable Java, go to your start menu, then the control panel. Open the Java application there and go to its security tab. Un-check the box entitled “Enable Java Content in the Browser.”
You should also run a virus scan just to be sure. This particular Java issue is usually picked up by Malwarebytes (http://download.cnet.com/
