Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Restoro to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is CryptoLocker ransomware? And how does it execute its attack?
CryptoLocker ransomware is a new version of a crypto-malware that was first discovered way back in 2013. Back then, CryptoLocker spreads using the Gameover Zeus botnet and even though the malware was quickly shut down by security experts, new versions of this threat just keep on emerging.
The moment CryptoLocker ransomware infiltrates a system it will scan the entire drive of the infected system and scan for several file types such as:
3fr, accdb, ai, arw, bay, cdr, cer, cr2, crt, crw, dbf, dcr, der, dng, doc, docm, docx, dwg, dxf, dxg, eps, erf, indd, jpe, jpg, kdc, mdb, mdf, mef, mrw, nef, nrw, odb, odm, odp, ods, odt, orf, p12, p7b, p7c, pdd, pef, pem, pfx, ppt, pptm, pptx, psd, pst, ptx, r3d, raf, raw, rtf, rw2, rwl, srf, srw, wb2, wpd, wps, xlk, xls, xlsb, xlsm, xlsx.
As you can notice, CryptoLocker ransomware targets various files. These targeted files are encrypted using the RSA encryption algorithm. Once the encryption is done, all these file types will be inaccessible. The malware then displays a ransom note that states:
“Your personal files are encrypted!
Your important files encryption produced on this computer: photos, videos, documents, etc. Here is a complete list of encrypted files, and you can personally verify this.
Encryption was produced using a unique public key RSA-2048 generated for this computer. To decrypt files you need to obtain the private key.
The single copy of the private key, which will allow you to decrypt the files, located on a secret server on the Internet; the server will destroy the key after a time specified in this window. After that, nobody and never will be able to restore files…
To obtain the private key for this computer, which will automatically decrypt files, you need to pay [specified amount of money in EUR or USD] similar amount in another currency.
Click To select the method of payment and the currency.
Any attempt to remove or damage this software will lead to the immediate destruction of the private key by a server.”
If you’re the kind of a user that keeps backup copies of important files, then CryptoLocker shouldn’t scare so there is no need for you to pay the ransom or use recovery software. However, if you only have one copy of your important files, then you’ll have a big problem. Worry not, since there are other recovery methods you can try to decrypt the affected files. And besides paying the ransom is not recommended as cybercrooks can’t be trusted and there is also no assurance that once you pay the ransom, the sly crooks will give you the decryption key. The best thing you can do is to eliminate the malware from your system first then try to recover the encrypted files.

Try to recover your encrypted files using their Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if ACCDFISA v2.0 hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
To restore the encrypted file, right-click on it and select Properties, a new window will pop-up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.
