CryptoLocker Windows Trojan. Back up your work
I don't normally do alerts for these things anymore, but friends of mine have been going a bit ballistic telling everyone to beware, so here we are.
This one is particularly nasty because it works so well, once you run the trojan it encrypts your files and then asks you to pay to get the files back. This is an old trick, I remember a DOS virus trying the same trick in the early 90's and I'm sure there have been tons of others, but, they weren't very good, this one is.
Right now I believe it's most commonly delivered as an email attachment, but expect to see the same code arriving via many different methods.
TLDR: Make a back up of your important files and keep it offline

Backing up applies to Mac users too, fortunately Apple made that easy.

Really useful info Cockforger, so pleased you appeared on another of my threads.
90% of home Windows users won't have a back up, but that's OK, just format the lot, problem gone. If one person reads this and does a back up, even to a DVD whatever that is then I've achieved.

Cryptolocker is a non-issue with a decent virus scanner, if you don't have a decent virus scanner then you are a muppet. Bioforger is right it is stupid scaremongering for anyone who has an ounce of intelligence and has a virus scanner installed.

I probably do more work on Windows machines than you could comprehend.
"Cryptolocker is a non-issue with a decent virus scanner" Show me this wonderful technology that can detect issues before they happen, many have tried and all have failed, any decent virus author runs his product through every antivirus product before launching it. You're a **** if you think you don't need to back up because you run antivirus.
Well, go ahead, take the advice of these ***** over an "Apple Fan" don't bother backing up and don't worry about malicious software, you have antivirus, it detects all known and future threats, McAfee told me so.

Don't all the companies selling anti-virus software write the viruses in the first place though? Keeps them in business after all

Not true. We did write viruses, sometimes had to, but these were instantly added to the detection list and shared with other antivirus companies, as is standard practice, even though they would never leave the lab.

I was joking but it seems like there might have been some truth in it after all

As for the detection what you say is true but that's what AV definition updates are for, which usually patch new virii pretty much as soon as they are announced. And if not on the same day pretty much the following day/week. MS patched Crypto in early September and some other variants of it later. So Security Essentials is ok if you use that. You need definition 1.157.1563.0 or above to be "safe".
