What is Explorer ransomware? And how does it execute its attack on your computer?

Explorer ransomware is another file-encrypting virus created using the open source platform, HiddenTear. Like other ransomware infections, it is designed to take your files captive in exchange for ransom money. Security analysts first observed Explorer ransomware in the second week of July 2017.
To execute its attack, it sends out an infected file attached to spam email messages. And if you made the mistake of downloading and opening the malicious file, explorer.exe, it starts to execute its attack by connecting to its remote server. After that, it scans your computer for important files to encrypt. It encrypts them using a strong cipher (AES) that would be hard to decrypt unless you have the decryption key which is of course stored away by the crooks. It appends .explorer extension to each targeted files and then drops its ransom note in a file named READ_IT.txt containing the following message:
All Your Documents ,Photos ,Databases And Other Impotant Personal Files Were Encrypted By A Strong Algorithm With Unique Key
To Restore Your Files, Contact Us With Email Address:

NOTE: If you Email Us in less than 24 hours, you will be paying half the regular price.

It urges you to write to [email protected] but it does not mention how much the ransom money is, usually, such infections demands amount ranging from $200-$1000 in Bitcoins. The crooks claim that if you don’t contact them within 24 hours, you’ll have to pay half the regular amount of the ransom. Keep in mind that no matter how desperate you are, you shouldn’t think about contacting these crooks for you might be getting yourself into even more trouble than you already are. It would be a lot better if you remove the ransomware and recover your files by following the instructions provided later on this article.
