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.

What is Napoleon ransomware? And how does it execute its attack?
Napoleon ransomware is a newly discovered ransomware threat on December 4, 2017. After a thorough observation, it seems that this new ransomware is not sophisticatedly created as it is coded poorly by the cyber crooks behind it. Nonetheless, this ransowmare is not to be taken lightly despite being coded weakly as it is still capable of encrypting files. Its code is based on the open source platform known as Hidden Tear. Based on research, Napoleon ransomware is triggered by a Trojan which is associated with another ransomware threat called “Blind”. This crypto malware was first identified on September this year and now, it seems that the code for this threat was modified and released on a new active attack in the form of Napoleon ransomware.
According to experts, Napoleon targets files with the following extensions:
.1c, .3fr, .accdb, .ai, .arw, .bac, .bay, .bmp, .cdr, .cer, .cfg, .config, .cr2, .crt, .crw, .css, .csv, .db, .dbf, .dcr, .der, .dng, .doc, .docm, .docx, .dwg, .dxf, .dxg, .eps, .erf, .gif, .htm, .html, .indd, .iso, .jpe, .jpeg, .jpg, .kdc, .lnk, .mdb, .mdf, .mef, .mk, .mp3, .mp4, .mrw, .nef, .nrw, .odb, .ode, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdd, .pdf, .pef, .pem, .pfx, .php, .png, .ppt, .pptm, .pptx, .psd, .pst, .ptx, .r3d, .rar, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .srw, .tif, .wb2, .wma, .wpd, .wps, .x3f, .xlk, .xls, .xlsb, .xlsm, .xlsx, .zip.
Once it is able to locate these extensions, it will start to encrypt them and append the [firstname.lastname@example.org].napoleon extension at the end of each files’ names. It then proceeds to create data recovery instructions in a file named How_Decrypt_Files.hta which contains the message below:
“Your documents, photos, databases and other important files have been encrypted
cryptographically strong, without the original key recovery is impossible!
To decrypt your files you need to buy the special software – NAPOLEON DECRYPTER
Using another tools could corrupt your files, in case of using third party
software we don’t give guarantees that full recovery is possible so use it on
your own risk.
If you want to restore files, write us to the e-mail: email@example.com
In subject line write encryption and attach your ID in body of your message

one week in interest of our security.

Based on its ransom note, it’s clear that the crooks behind Napoleon ransomware wants to look trustworthy by offering its victims a free decryption of three files that must not exceed 2MB. Victims are urged to contact the crooks within a week else they will delete the Napoleon decryptor used to recover the encrypted files. No matter how tempting recovering at least three files are, you should know that these crooks can’t be trusted and under no circumstances should you contact and negotiate with them as you’ll only end up losing money for nothing. And besides this would only motivate them to create more ransomware threats. You need not add fuel to the fire and look for ways instead to remove Napoleon ransomware and recover the encrypted files using alternative methods.
How does Napoleon ransomware spread its malicious payload?
