How to remove .Where_my_files (Ransomware Removal Guide)


.Where_my_files ransomware is a dangerous computer virus that encrypts the files on your computer, adds .Where_my_files to the file extension name, and leaves a ransom note named Where_my_files.txt (or other) on the computer demanding a payment in order to decrypt and recover files.

The ransom note contains information and instructions about how to obtain a individual private key to decrypt your files. However, in order to do so the malicious program wants you to purchase the key and a special decryptor for an excessive price via Bitcoin.

When .Where_my_files ransomware infects a computer it will scan all the local drives for certain file types. Once it locates a specific file with the right file extension it will encrypt the file and add a .Where_my_files extension to the encrypted file name. For example, botcrawl.png will be encrypted to the filename botcrawl.png.Where_my_files. Here are the types of files that .Where_my_files ransomware encrypts:

.c, .h, .m, .ai, .cs, .db, .nd, .pl, .ps, .py, .rm, .3dm, .3ds, .3fr, .3g2, .3gp, .ach, .arw, .asf, .asx, .avi, .bak, .bay, .cdr, .cer, .cpp, .cr2, .crt, .crw, .dbf, .dcr, .dds, .der, .des, .dng, .doc, .dtd, .dwg, .dxf, .dxg, .eml, .eps, .erf, .fla, .flvv, .hpp, .iif, .jpe, .jpg, .kdc, .key, .lua, .m4v, .max, .mdb, .mdf, .mef, .mov, .mp3, .mp4, .mpg, .mrw, .msg, .nef, .nk2, .nrw, .oab, .obj, .odb, .odc, .odm, .odp, .ods, .odt, .orf, .ost, .p12, .p7b, .p7c, .pab, .pas, .pct, .pdb, .pdd, .pdf, .pef, .pem, .pfx, .pps, .ppt, .prf, .psd, .pst, .ptx, .qba, .qbb, .qbm, .qbr, .qbw, .qbx, .qby, .r3d, .raf, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .srt, .srw, .svg, .swf, .tex, .tga, .thm, .tlg, .txt, .vob, .wav, .wb2, .wmv, .wpd, .wps, .no, .xlk, .xlr, .xls, .yuv, .back, .docm, .docx, .flac, .indd, .java, .jpeg, .pptm, .pptx, .xlsb, .xlsm, .xlsx

.Where_my_files ransomware will also a ransom note in the Documents and Desktop folders. The ransom notes contain information about what happened to the files, links to the TOR payment sites, and a unique ID that must be used to login to the payment site.

The ransomware will also create an autorun for the malware executable file so that it will run every time Windows starts. The autorun is called MSEstl and the executable file can be found here: %UserProfile%\AppData\Roaming\Microsoft\Essential\msestl32.exe.
