Pay close attention to when and when not to remove the virus. A common mistake is removing the virus before understanding how to remove it.
PRO TIP: Read all of the following before taking any action.
BEST: I have a Backup that is Not Connected to the Computer.
If this is you, start here. If you don’t have a backup, skip to the next section.
STEP 1: Get rid of the virus. Otherwise any actions you take could result in the backup and your restored data becoming compromised.
STEP 2: Once the virus is for sure removed, simply restore your backup.
STEP 3: Get better comprehensive protection to protect yourself from modern threats. Anti-virus protection is no longer enough.
SECOND BEST: I have Online Backups.
If this is you, start here. If not, skip to the next section.
STEP 1: Lock or disable any further backups. Otherwise your computer will backup the encrypted files.
STEP 2: Likely the encrypted files were backed up.
a) You must determine if your online backups are your original unencrypted files.
b) If the online backups are encrypted, check to see if the online backup service keeps older versions that wouldn’t be encrypted. Some online backup services call this “versioning”, meaning when a file is backed up with the same filename that already exists at the online backup service, they keep the older version as well for a time.
c) If the online backups are encrypted, skip to the next section in caps.
Only continue in this section if your online backup service keeps a history of files changed or your online backup
STEP 3: Get rid of the virus. Otherwise any actions you take could result in the backup and your restored data becoming compromised.
STEP 4: Once the virus is for sure removed, simply restore your backup from your online backups.
STEP 5: Get better comprehensive protection to protect yourself from modern threats. Anti-virus protection is no longer enough.

STEP 1: First if the damage is already done, do NOT delete the virus.
It’s important to know which virus you have been infected by based on it’s behavior. Otherwise, you won’t know which method will help you potentially restore your files.
STEP 2: Identify the ransomware based on the ransom note and one of the encrypted files here: https://id-ransomware.malwarehunterteam.com
There are hundreds of known ransomwares. It’s important to identify the specific type of ransomware as each has a different removal and decryption of files instructions.
STEP 3: One you identify your specific ransomware, search online for specific removal instructions and any possible decryption of files instructions. Since there are hundreds of variations, we only list below specific links to some of the more common ransomware.
STEP 4: Unless the removal instructions advise otherwise, remove the virus.
STEP 5: Attempt decryption.
