The infamous STOP ransomware has been detected in new active attack campaigns by security researchers. The new variant that comes under 188 number appears to be set to use the extension .msop for files it encrypts. That’s why the new variant is dubbed .msop file virus. The decryption key price varies between $490 and $980 in Bitcoin. It depends on the time that has passed before the victim contacts hackers. Keep reading this Msop ransomware removal guide to learn how to remove malicious files completely from the infected PC and potentially recover .kodg files.

Infection Flow of Kodg Virus Files
Once the Msop ransomware is installed on the computer it creates randomly named executable files in the %AppData% or %LocalAppData% folders. Infection with the newest STOP ransomware variant – Msop virus starts the moment its payload is executed on the targeted host. The payload controls all malicious system modifications that aim to ensure the stable presence of Msop ransomware on the computer. The Msop file virus can read, update and delete some system files or create new malicious files in order to complete the infection.
Once Msop file virus establishes all its files and objects on the infected host it initiates a scan of all drives to encrypt all files that belong to one of the following types:
.001, .002, .003, .004, .005, .006, .007, .008, .009, .010, .011, .123, .1cd, .3dm, .3ds, .3fr, .3g2, .3gp, .3pr, .602, .7z, .7zip, .ARC, .CSV, .DOC, .DOT, .MYD, .MYI, .NEF, .PAQ, .PPT, .RTF, .SQLITE3, .SQLITEDB, .XLS, .aac, .ab4, .accdb, .accde, .accdr, .accdt, .ach, .acr, .act, .adb, .adp, .ads, .aes, .agdl, .ai, .aiff, .ait, .al, .aoi, .apj, .apk, .arw, .asc, .asf, .asm, .asp, .aspx, .asset, .asx, .avi, .awg, .back, .backup, .backupdb, .bak, .bank, .bat, .bay, .bdb, .bgt, .bik, .bin, .bkp, .blend, .bmp, .bpw, .brd, .bsa, .cdf, .cdr, .cdr3, .cdr4, .cdr5, .cdr6, .cdrw, .cdx, .ce1, .ce2, .cer, .cfg, .cgm, .cib, .class, .cls, .cmd, .cmt, .config, .contact, .cpi, .cpp, .cr2, .craw, .crt, .crw, .cs, .csh, .csl, .csr, .css, .csv, .d3dbsp, .dac, .das, .dat, .db, .db3, .db_journal, .dbf, .dbx, .dc2, .dch, .dcr, .dcs, .ddd, .ddoc, .ddrw, .dds, .der, .des, .design, .dgc, .dif, .dip, .dit, .djv, .djvu, .dng, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .drf, .drw, .dtd, .dwg, .dxb, .dxf, .dxg, .edb, .eml, .eps, .erbsql, .erf, .exf, .fdb, .ffd, .fff, .fh, .fhd, .fla, .flac, .flf, .flv, .flvv, .forge, .fpx, .frm, .fxg, .gif, .gpg, .gray, .grey, .groups, .gry, .gz, .hbk, .hdd, .hpp, .html, .hwp, .ibank, .ibd, .ibz, .idx, .iif, .iiq, .incpas, .indd, .iwi, .jar, .java, .jnt, .jpe, .jpeg, .jpg, .js, .kc2, .kdbx, .kdc, .key, .kpdx, .kwm, .laccdb, .lay, .lay6, .lbf, .ldf, .lit, .litemod, .litesql, .log, .ltx, .lua, .m2ts, .m3u, .m4a, .m4p, .m4u, .m4v, .mapimail, .max, .mbx, .md, .mdb, .mdc, .mdf, .mef, .mfw, .mid, .mkv, .mlb, .mml, .mmw, .mny, .moneywell, .mos, .mov, .mp3, .mp4, .mpeg, .mpg, .mrw, .ms11, .msg, .myd, .n64, .nd, .ndd, .ndf, .nef, .nk2, .nop, .nrw, .ns2, .ns3, .ns4, .nsd, .nsf, .nsg, .nsh, .nvram, .nwb, .nx2, .nxl, .nyf, .oab, .obj, .odb, .odc, .odf, .odg, .odm, .odp, .ods, .odt, .ogg, .oil, .onetoc2, .orf, .ost, .otg, .oth, .otp, .ots, .ott, .p12, .p7b, .p7c, .pab, .pages, .pas, .pat, .pcd, .pct, .pdb, .pdd, .pdf, .pef, .pem, .pfx, .php, .pif, .pl, .plc, .plus_muhd, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prf, .ps, .psafe3, .psd, .pspimage, .pst, .ptx, .pwm, .py, .qba, .qbb, .qbm, .qbr, .qbw, .qbx, .qby, .qcow, .qcow2, .qed, .r3d, .raf, .rar, .rat, .raw, .rb, .rdb, .re4, .rm, .rtf, .rvt, .rw2, .rwl, .rwz, .s3db, .safe, .sas7bdat, .sav, .save, .say, .sch, .sd0, .sda, .sdf, .sh, .sldm, .sldx, .slk, .sql, .sqlite, .sqlite3, .sqlitedb, .sr2, .srf, .srt, .srw, .st4, .st5, .st6, .st7, .st8, .stc, .std, .sti, .stm, .stw, .stx, .svg, .swf, .sxc, .sxd, .sxg, .sxi, .sxm, .sxw, .tar, .tar.bz2, .tbk, .tex, .tga, .tgz, .thm, .tif, .tiff, .tlg, .txt, .uop, .uot, .upk, .vb, .vbox, .vbs, .vdi, .vhd, .vhdx, .vmdk, .vmsd, .vmx, .vmxf, .vob, .wab, .wad, .wallet, .wav, .wb2, .wk1, .wks, .wma, .wmv, .wpd, .wps, .x11, .x3f, .xis, .xla, .xlam, .xlc, .xlk, .xlm, .xlr, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .ycbcra, .yuv, .zip
All target files are modified via the strong cipher algorithm AES. The encryption process transforms the original code of target files by making them completely unworkable until the decryption key is applied to the decryptor. Then Msop ransomware renames encrypted files and marks them with the .msop file extension.
The Msop virus also loads Windows Registry editor to create new registry values under keys like Run and RunOnce that will help the automatic execution of its payload each time the Windows OS starts. Furthermore, some values under the same keys may be deleted or replaced so that the ransomware can generate its ransom note automatically on the screen. Before this Msop files virus drops the file that contains its ransom message. This file is named _readme.txt

The Msop ransomware is designed to localize the infected host so it can present the ransom message in the appropriate language. The message provides two addresses that enable victims to contact hackers for further details about the ransom amount and its payment. The STOP Msop ransomware malicious opearators attempt to blackmail their victims into paying a ransom that starts from $490 and may reach $980. They demand the amount in Bitcoins. Supposedly, the payment process should enable infected users to restore their .msop files.
However, there is no guarantee that they will send a working decryption tool even after an eventual successful payment. If you want to regain the security of your PC and retrieve .msop files, check the removal guide below and follow the steps.
Msop Ransomware Distribution
The Msop ransomware is distributed mainly via spam email messages that follow a typical pattern of sending legitimate alike blank emails with malicious attachments. The Msop virus infected emails contain malicious files archived in .7z format that generally are presented as “Status of invoice”. The email may also be presented as information of package delivery failure or notifications of shipment status. These techniques aim to provoke curiosity and interaction with the attached file. Spreading ransomware through archives is a staple of this type of malware. The attached file contains malicious VBS file that once opened triggers the Msop ransomware infection. Other distribution techniques may be browser hijackers, malicious ads and redirects and dangerous software installation packages downloaded from untrusted sites.
Remove Msop Ransomware Virus and Restore PC
Please note that paying the requested ransom fee to cybercriminals does not really solve your problem with Msop cryptovirus. In fact, you only encourage hackers to continue spreading ransomware of this kind. Instead, you must remove the threat immediately, and only then look for optional ways to recover your data.
WARNING! Manual removal of Msop ransomware requires being familiar with system files and registries. Removing important data accidentally can lead to permanent system damage. If you don’t feel comfortable with manual instructions, download a powerful anti-malware tool that will scan your system for malware and clean it safely for you.DOWNLOAD SpyHunter Anti-Malware Tool
