A ransomware virus like Merl is one infection that is really hard to deal with particularly if it manages to lock common files on the computer. This piece of notorious malware mainly targets universal files like documents, presentations, spreadsheets, databases, archives, photos, images, videos, and so on. Initial objective of Merl is to block user’s access to these files by encrypting it with a complex algorithm. It also appended a .merl extension to all infected files. Afterwards, attackers start to offer their own recovery tools at an expensive value.

Ransom money demanded by attacker is a costly $980 as payment for the Merl Decryptor. But if victim wants to avail the discounted price, payment should be remitted within 72 hours after the initial infection. Here is an excerpt from the ransom note:
