I am looking for antivirus working in windows (7/8/8.1/10) which is able to remove Cryptographer virus completely. Can you recommend an antivirus which kills this Trojan that encrypts the files?

    ok, what do you mean by remove? Do your mean remove just the virus (even if your files are now encrypted) or unencrypt your files and remove the virus? – Tom Mar 12 '16 at 17:03

    I mean a software that remove the Trojan which encrypt the files. Those encrypted files are gone, no way to have them back unless to pay! – Woeitg Mar 12 '16 at 17:05
  • Exactly, I'll add an answer now but it looks like Avast may be able to do the trick – Tom Mar 12 '16 at 17:07

    If you already made peace with your files gone: Do a clean reinstall. The system is infected, your AV solution failed, in my opinion everything you do now will not result in a system I would still regard as compromised. Hopefully you had backups! – idkfa Mar 14 '16 at 15:00

According to Symantec, they have a product called Norton Power Eraser (NPE) that should be able to remove the Cryptolocker virus/trojan. For information provided by Symantec, see this page. At the time of this writing, it was last updated on August 6, 2015, 3:39:36 PM.

You can download the latest version of this program from this link.

While not explicitly an AV solution, I've tried a few solutions and have settled on Rollback Rx. It's a solid program, it's recovered my PC on a handful of occasions from Cryptolocker or other malicious content.

The only downside is that the program needs to be installed on a clean system; it can't be used on a system with Cryptolocker. Still, in terms of performance and pure reliability in resolving the issue I think it's an easy choice.

    The OP explicitly talks about a system already infected. That conflicts with the requirement needs to be installed on a clean system – user416 Mar 14 '16 at 13:13

Avast! Antivirus detects all known variants of CryptoLocker thanks to our automated processing and CommunityIQ,” said Pavel Sramek, researcher and analyst for the avast! Virus Lab. “There are less than a dozen; this doesn't seem to be a case of rapidly mutating malware.”

AVAST users should be safe from infection during the short period when the malware is new and "undetected" as long as AutoSandbox and DeepScreen are active. “The infection is prevented by means of a dynamic detection,” said Sramek.

Avast Free Antivirus 2016 offers an antivirus and anti-malware protection, along with features you're most likely to need, but would rather not think about - like one-click system checks, and unwanted toolbar removal. The free home network scanner now detects 12 more types of router vulnerabilities, and a new password manager feature means your antivirus can now save, and encrypt, all your passwords.

    Avast is what the user had installed when he received the CryptoLocker: "At the time the computer get affected, avast was running on computer!!!" – Woeitg – Tom Apr 6 '16 at 1:39
