New, tougher ransomware irreversible, authorities warn

You already know to be alert for ransomware. Now, meet a version that irrevocably renders an unwary web surfer's computer useless and irreversibly blocks access to your files.

Ocean County Prosecutor Joseph D. Coronato's High Tech Crime Unit today issued the alert about the scam that they say is infecting computers throughout the United States and in at least 20 countries in Europe.

The battle between anti-virus companies and hackers is ongoing, and the newest version of ransomware indicates that the stakes have climbed. Investigators say there is no way to reverse the newest strain, and any files in it are lost unless you've backed them up in secondary storage, such as a thumb drive.

It can infest your system from a website you've visited, an e-mail, or a social-network instant message, and lock up your unit..

Occasionally, a pop-up window or a web page warning appears, informing you that you've been engaged in some sort of illegal enterprise. The unit is locked down and unusable until the program is removed.

You're usually informed that you'll have to pay a fine to receive a code to unlock the computer. Don't do it, investigators warn.

They advise keeping all anti-virus programs and security software current, keeping firewalls engaged, avoiding spam messages or links to unfamiliar websites, and copying crucial files to secondary storage.
