Osiris.dll Virus Removal (File Recovery Steps)


In this article we are going to try and help you remove Osiris.dll Virus. Our instructions cover all Windows versions.

The most disturbing cyber threat you may ever come across online is a Ransomware-based virus. These malicious programs are considered to be the most dangerous viruses ever created. In this article we will be discussing one of them – Osiris.dll Virus. What this type of malware usually does is penetrate your system, detect which files you cherish most and encrypt them all. Then you will be required to pay ransom to bring them back. This is a perfect example of harassment and we are going to give you all the corresponding details below.

What is Ransomware? How does it function?

Ransomware is a type of malware, whose main expertise is asking for ransom in exchange for undoing what it has done to your PC. There are various types of Ransomware, which we will elaborate on in the next paragraph. What you should know is that malware of this type is generally extremely hard to remove and it is usually even harder to undo whatever negative thing it has done to your computer. Even experts might find it awfully difficult to deal with the effects of this malware.

Types of Ransomware. Where does Osiris.dll belong?

The functions of the Ransomware-based viruses entirely depend on their subtype. Here are the different kinds of existing Ransomware:

  • Mobile Ransomware viruses – the ones that attack your smartphones and tablets and are known to lock the screen of these devices. Then they demand ransom in order to unlock it.
  • Monitor-locking Ransomware viruses – the ones that could only affect your computer or laptop’s screen in the same way as the mobile Ransomware does – by making the desktop unavailable until you pay ransom to access it again.
  • Authority-exploited Ransomware – sometimes some government agencies use such viruses to make criminals pay fines for certain violations. So, basically, this type is not evil, but functions in a similar way.
  • The most famous fileencrypting Ransomware subgroup – the malware versions of this subtype are the most commonly spread. These programs are probably the worst type of Ransomware as they infect your PC, determine which files you will miss most (the ones that you commonly use); and makes them inaccessible to you. After that you are harassed into paying ransom in order to decrypt them. Osiris.dll belongs to this subgroup and acts in the way as we have already described in the opening paragraph.

How could you catch such an awful threat?

Sadly, you can never be sure how exactly you have encountered such a disturbing virus as Osiris.dll. There are endless possibilities: contagious web pages, torrents, shareware, and streaming websites. The most common among them are the so-called fake ads (the product of a practice called malvertising), which represent pop-up ads that redirect you to contagious online locations. As soon as you click on such an ad, you get infected with the virus. Another possible source is the fake system update requests. Sometimes suspicious update requests appear on your monitor and they do not come from your OS, they are simply pop-ups, working in the same way as the fake ads do – once clicked on, they sneak the virus inside your PC. Also, usually spam emails and their attachments could contain Ransomware (even accompanied by Trojans in some cases) and immediately after you open such a letter or its attachments, your computer may get contaminated.

What you could do next if you get the Ransom-demanding notification

We must say that in most cases the odds are not in your favor. Such cunning viruses as Osiris.dll are extremely hazardous partly because the infection before the notification is usually invisible and after getting the message, it becomes too late. We just need to tell you that paying the ransom has never been a good idea. This should be your last option only in case nothing else really works. You can always ask someone involved in this industry for help – people have certain knowledge and experience and might know how to remove such a virus and return your files to you. Also, you may need to do a little research and download a powerful tool against such malware if there is any. It could be paid, but it is still better to spend your money on that, not on agreeing with the hacker’s demands. What we recommend most is to follow the steps below. The Removal Guide there should be what you need to remove the contamination. Still, we cannot promise that getting rid of the virus will decrypt your encrypted data, but it is worth a try.
