How does this ransomware work?

.aaa File Extension virus is a version of Cryptowall 3.0 virus. It is a powerful software that is capable of encrypting your files via RSA-2048 encryption method. When this virus attacks your computer, it finds and locks all personal files including these file types:

.doc, .docm, .docx, .cdr, .cer, .cr2, .crt, .crw, .dbf, .dcr, .der, .dng,.dwg, .dxf, .dxg, .eps, .erf, .indd, .jpe, .jpg, .mrw, .nef, .nrw, .odm, .odp, .ods, .odt, .p12, .p7b, .p7c, .pdd, .pem, .pfx, .ppt, .pptm, .pptx, .psd, .pst, .ptx, .raw, .r3d, .raf, .rtf, .rwl, .srf, .srw, .wb2, .wpd, .xls, .xlsm, .xlsx, .wps, .xlk, and many other file types as well.

Once this virus affects these files, they will become unattainable. You will not be able to open them, review them, or use them. What is more, this virus leaves a ransom note in each folder that has the infected files in it. These ransom notes can be entitled as:

HELP_YOUR_FILES.TXT

HELP_YOUR_FILES.PNG

HELP_YOUR_FILES.HTML

The ransom note provides an explanation what you should do to get your files back. The developers of this cyber threat ask you to pay a ransom in order to access your files; they promise to give you a decryption key right after you pay a fixed amount of money.

Do not let cyber-criminals steal your data AND your money from you. Computer experts say that you should not support cyber criminals, especially because there are no assurance that they are going to give you the decryption key. What we recommend doing is removing this virus as soon as possible. You can do that with an anti-malware program, for example, Reimage. You also have an option to remove .aaa File Extension ransomware manually (not recommended for inexperienced computer users). To find the manual removal guide, proceed to page 2.
