Hello jainyichen, Welcome! If you're using licenced Kaspersky software, open a support ticket in your MyKaspersky account, https://my.kaspersky.com, send them a sample of an encrypted file, make sure you mark the .zip "CONTAMINATED RANSOMEWARE", also send the same unencrypted file if you have available.

1. https://www.enigmasoftware.com/docmransomware-removal/ may help.
2. https://www.nomoreransom.org/crypto-sheriff.php?lang=en may help.
3. DCOM is not listed: https://id-ransomware.malwarehunterteam.com/index.php?lang=en
4. Posting to: https://www.kasperskyclub.com may help.
5. Kaspersky offers utilities (not for .DCOM): http://support.kaspersky.com/viruses/utility
6. STOPDecrypter decryption tool does not offer support for .DCOM.

1. If you're using any Kaspersky FREE sofware please post back, as there is no access to Kaspersky Technical Support without a valid licence.
2. Also please clarify: you installed a clean OS and restored all the files that were encrypted or did you restore files that were not encrypted but now are encrypted?

Please let us know? Thanks!
