The original term ACCDFISA stands for Anti Cyber Crime Department of Federal Internet Security Agency. Unfortunately, this abbreviation has been used by hackers for fraudulent purposes since yesterday or so. They are planting a vicious virus onto computers that locks Windows displaying “Warning! Access to your computer is limited” fake alert screen entitled “ACCDFISA Protection Program”. According to that message, your PC has been noticed to indulge in spamming, illegal sites advertising and other forbidden things – so your Operating System gets blocked until you pay the fine of $100 via MoneyPak, Paysafecard or Ukash services. The malware concurrently checks your hard drive against all .txt, .xml, .doc and some other file types, encrypts them and stores these encrypted items inside the Wcmtstcsys.sss location. All of these files get modified and obtain the .aes extension instead of the original one, therefore they become unreadable and inaccessible. Another problem is you won’t get the problem solved even after submitting the fee as it has been proven that all of the encrypted files get erased afterwards. So we offer you an alternate fix to eradicate the ACCDFISA virus and get your files back.
This ransomware tends to restrict the access to your desktop, displaying the screen shown on the image attached (see the snapshot). It says you need to enter the Control Code to open your desktop, and this code can be received only after you make the payment. So to bypass this, enter this 7534919801679213 – and get your Windows interface restored.
The badware also blocks the Internet connection by means of changing your default connection settings and assigning new IP, Gateway and Subnet Mask values. So go to your connections, pick the current one, click the TCP/IP properties and set the correct values in there (contact your ISP for relevant connection data), or – if possible – get them assigned automatically.
Now that you got your desktop back and the Internet connection restored, it’s about time to delete the ACCDFISA malware proper. So install the cleaner program below and let it handle the bug.
When the virus is gone, you’ll need to decrypt your files. So install WinRar from a reliable location on the web. Then, use Notepad to open %System%\wcmtstcsys.sss file which is packed with your files that had been added to the archive by the infection. You should now go into the folders listed under the above directory and manually rename every .aes file to .rar extension instead. This being done, you should right-click on the just renamed files and initiate extraction process to an appropriate location.
Hopefully this guide helps you cope with this awful virus. Let us know if something goes wrong. Best of luck!
