Find an OS that can't get infected by it. Just like the poster above said.

Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

A practical solution to the cryptolocker virus issue:

1) Pay the ransom. Word on the street is that when the ransom is paid within the time frame the data is unencrypted
2) Back up the data to an offline storage
3) This is the most critical step Replace Microsoft Windows with GNU/Linux and propriety software with Free Libre Open Source software. This has the following advantages:
   a) It prevents any further infection from cryptolocker
   b) It allows the victim to recover the cost of the ransom over time by not paying for proprietary operating systems, proprietary software and proprietary "security" solutions
   c) It helps deter further criminal activity of this nature by removing one potential victim from an operating system that has over time been proving to be notorious for malware, viruses and the like.
If you are a gamer, the choice to go over to Linux isn't really an option. Some software is just made for Windows. Sad

Gamers love to download stuff like cracks and cheats that have viruses in them....  Shocked

Just partition the hard drive and use Windows for gaming and Linux for everything else. Use boot select for OS selection.

I've never downloaded a single crack that contained a virus. That's an issue with the gamer.

Actually the gaming scene on GNU/Linux is changing for the better fast with Valve porting Steam to GNU/Linux. In situations where one has to use software which is only available on Microsoft Windows and there is no FLOSS alternative there are options that can at the very least mitigate the risk of infection and cost.
1) Run the software under Wine
2) Run Microsoft Windows in a virtual machine that is used only to run the software in question.
3) Run a dual boot configuration and use the Microsoft Windows side only to run the software in question.
The key is to move the main computing activity, in particular web browsing, email, and the exchange of documents away from Microsoft Windows.

If the withdrawal pains form Microsoft Windows are very high one does not have to go "cold turkey". There are ways to gradually eliminate the addiction.

She was pretty flustered and said that it was actually her work computer, so I don't think she could take me there to see it.

So why is it HER problem? She should call IT. And management should fire IT for incompetence as they obviously didn't secure the network properly.

If she was a self employed person or a business owner then there's no reason you could not get access to the computer. So I assume she is a wage earner.

Maybe she was afraid of being fired but if her boss would fire her for something which is not her fault (as on a properly secured computer she shouldn't be able to install any software without admin privileges) he is a lousy boss and she could probably sue for wrongful termination.

Unless she is the responsible IT person for the company then she deserves to get fired anyways for not doing her job properly. Wink

You can't secure a network against human stupidity. IT most likely has no fault. People will open every attachment they get sent, especially on their work emails and if the emails look work related(a complaint, an order, etc.).

Word on the street is that the dudes keep their word for better or worst. You pay up on time, your files get decrypted. You pay late by 1 minute or don't pay at all and you're screwed, it just uninstalls itself and leaves you with a bunch of encrypted files.

If the files were important enough to pay ransom, the hackers may want to take a look at them as well; I would not be surprised if the virus sends a copy to the hackers while unencrypting the files.

Nothing is secure against human stupidity.

And management should fire IT for incompetence as they obviously didn't secure the network properly.

At the present day, there is no mainstream antivirus that detects all variants of Cryptolocker.
‘Properly securing’ network against this particular virus includes (but not limited to):
-   Disallowing all *.exe and *.zip attachments
-   Disallowing execution from %AppData%, %LocalAppData% folders and subfolders
-   Disallowing execution from Zip, 7Zip, WinRar, WinZip, and other such utilities TEMP folders
As you can imagine this poses a few side effects, such as Adobe applications updates stopping working.
How can an IT administrator stop users from clicking on email attachments?

Keep a track of the emailing system, or even a workaround which disables attachments until an IT reviews them (not efficient, but works).

If you are a gamer, you wont have critical life-and-death files or software on your hd. If you are a (small) business, relying on MS windows at this point in history is russian roulette.
