I am sure the writers of the malware re-wrote it anyway, as that's what they always do to try and keep ahead of the anti-malware brigade.
When things like that strike you should not click anything, or even move your mouse, power off at the main switch. Then boot into Safe Mode and see if you can wind back using System Restore.
If not then I suggest posting a Hijackthis log on specialist forums such as BleepingComputer for instance.
If not Safe Mode then exit out of the pop-up/ad without clicking on anything inside it by using the Task Manager. This will terminate the browser at the root level without executing anything within the pop-up/ad.
I moved this out of Breaking Security News to Malware Discussions > Home User Assistance as a better spot for it.
As btstevens says if no back ups then try System Restore and if that fails then format and reinstall the system would probably be the only alternative.
I am having the same issue. system attacked by cryptolocker and same is the case when i try uploading an infected file to that website. did you find any solution ?
Thanks for the reply brother. the problem is that the only solution on this web page that may have solved my problem is system restore which i cannot do because being the dumbest person on the planet that i m i formatted and re installed my windows and don't have a restore point. Now probably I m screwed but there must be something that can help ? most of my files are encrypted by cryptolocker and now that it is gone and all the chances of paying ransom and getting a private key to decrypt my files are gone with it, the only option I have is to find a solution to restore them.
Probably a variant by now as it's been around for a while. There's no guarantee your files would have been made available to you anyway no matter what ransom you paid, so never, ever pay one unless you like financing crime syndicates. As per my link, at the first hint of this kind of trouble, do NOT touch any keys or your mouse because that is what activates it....power off immediately, pull the plug at the power switch if necessary.
In this case you are too late so I would do a long format and reinstall your system. As a precaution remove any attached drives as they may be harboring these things. Then, for the future, be extra careful what you download, where you surf and look out for hidden extras when installing software.
I have already formatted the system drive partition and re installed windows but i have important data on other partitions which is infected (encrypted). So does that mean that I can never recover those files that are infected ?
