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.
We recommend downloading Restoro to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is Evasive ransomware? And how does it implement its attack?
Evasive ransomware is another new encryption ransomware Trojan designed to take victim’s files as hostage in exchange for a ransom. Evasive ransomware’s source code came from the open source platform, Hidden Tear. It utilizes the AES cryptography in encrypting files and adds the .locked extension on each one of the targeted files. This new ransomware Trojan tends to target popular file formats in order to cause more damage to its victims and make them pay the ransom. According to security experts, it mostly targets files with the following extensions:
.aspx, .cpp, .csv, .doc, .docx, .h, .html, .jpg, .jsp, .lnk, .mdb, .odt, .pdf, .php, .png, .ppt, .pptx, .psd, .pst, .rar, .sql, .txt, .xls, .xlsx, .xml, .zip.
During the encryption, it applies the AES cipher in encrypting the files and appends the .locked extension on the affected files. Following the encryption, it drops a ransom note in READ_ME.txt file containing the following message:
“Dear fellows, Attention please!
As you may noticed, all the data on your computer has been encrypted.
To decrypt the files, each of your computer need a privatekey which is held by us.
We guarantee that your files can be 100% restored only with our help.
Your leadership (anyone who’s in charge) should email us at [email protected] within the next 12 hours.
Remember, you only have 48 hours to get the keys before your data lost forever.
Backup Email: [email protected]”
On its ransom note, Evasive ransomware displays a message telling its victims to contact the crooks through [email protected] within 12 hours since the attack. They even provided a backup email address, [email protected], in case something goes wrong with the first one they’d given. In addition, they also tell users that the decryption key is only available for 48 hours. Clearly, this is just another ploy to get its victims to panic so that they’ll contact the crooks behind this threat and pay the ransom. Security experts from SemVirus.pt advises users to stay calm and do not do anything rash such as paying the ransom as there are other ways to recover the encrypted files without giving in to the cyber criminals’ demands.
How does Evasive ransomware spread?
According to researchers, Evasive ransomware spreads through malicious spam email attachment in spam emails. The malicious payload responsible in installing Evasive ransomware to the system might be presented as a harmless looking Word, PDF and other file. Cyber criminals often disguises the email as something that would get the user’s attention so that they’ll open the email and download the attachment which is why you should always look up for any signs of phishing email instead of rushing to download and open the attachment. It would be better if you also keep both your system and antivirus program updated to increase your computer’s resistance against ransomware infections and other threats.

Step 10: Delete the registry keys and sub-keys created by Evasive ransomware.
Step 11: Close the Registry Editor.
Step 12: Empty your Recycle Bin.
Try to recover your encrypted files using the Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if Evasive ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
To restore the encrypted file, right-click on it and select Properties, a new window will pop-up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.
To make sure that Evasive is completely removed and that nothing is left behind, use the following antivirus program. To use it, refer to the instructions below.
