New scam holds your computer files for ransom
If you're not backing up your computer files on a daily basis, now may be the time. The National Consumer's League is warning about a pernicious and growing malware scam that infects users computers with something called "cryptolocker."
Spread via email, bogus websites and Facebook videos, the malware encrypts the contents of your hard-drive, making it impossible for you to retrieve your files. The moment the virus infects your computer, it tells you with a ransom note that demands hundreds of dollars in untraceable payments to "decrypt" your system. But according to the FBI, decryption is not possible.
Naturally, the best way to deal with this nightmare is to avoid it. Make sure your security software is up to date, and don't open email files that appear suspicious. What makes files suspicious? They're sent by an unfamiliar user or appear to be coming from a friend, but with a message that seems unlikely, like "OMG. Look at this" or "This video is amazing."
If you're tempted to click on the video, reply to the sender first, asking if this came from them or if their email address has been hijacked. Waiting a few extra minutes for a response could save you a bundle in time and money.
Chris Duque, a retired Honolulu police detective who has become an expert in cybercrime, says he thinks the virus is most likely to be caught by Facebook users, many of whom click on shared videos. The tip-off is likely to be a message that says you'll need to download some software to watch. Don't do it. The moment you authorize the software download, it opens your system to the malware. The next warning is the pop-up ransom demand. And then it's too late.
