This page aims to help you remove .Osiris Virus File for free. Our instructions also cover how any .Osiris file can be recovered.

The following article features information related to one of the latest ransomware variants known as .Osiris. We will explain what the virus is, how it operates and most importantly – how you get infected. Furthermore, at the bottom of the article you will also find a removal guide designed to walk you through the detailed steps that will help you clean your system from this treacherous malware. It’s important that you do indeed remove the virus, as leaving it on your PC may still grant the hackers access to it, which may result in a further encryption after you’ve already dealt with this one. In addition to this, we’ve also included instructions that will attempt to retrieve the encrypted files and restore them to their initial state.

How .Osiris Virus gets in your system

You may or may not recall the exact instance when you contracted this ransomware. There are several common ways that cyber criminals use to distribute their malicious payload the most effective of which has proven to be malvertising. This is the practice of injecting an existing online advertisement with a virus or creating a new one from scratch that has been embedded with the harmful program from the start. If you happen to click on one such ad, be it a popup, banner or box message, you end up automatically downloading the ransomware onto your machine. The process is a notoriously ‘silent’ one and you will see no indication of the contamination. Another very likely way you may have gotten infected could have been through a malicious attachment in a spam email. Hackers often employ the help of a Trojan horse virus to help ‘transport’ the ransomware into the victim’s system. The Trojan is downloaded the moment you open the attached file (can be as innocent-looking as a Word or PDF document) and it in turn automatically downloads .Osiris the second after. This, too, happens without any sign or indication, so you won’t be aware of what’s going on. This is also one of the key reasons for the success of .Osiris Virus– its stealth.

How to prevent future infections

Well, you already have the knowledge of the main pathways ransomware like .Osiris Virus File uses to get to its targets, so you should work your way from there. If spam messages are a likely source – treat incoming emails with extra caution. Don’t open any emails you’re unsure of and definitely do not open or download attachments that look suspicious. As for the malvertisements, the only logical way to make sure you’re safe from them is to simply avoid them. Avoid any and all forms of online advertising, as there is no way of telling the difference between a legitimate ad and a malicious one. Other possible sources are usual harmful, shady-looking websites and potential downloadable content from untrustworthy pages like that. Use your common sense and if you see that a page doesn’t look reputable – close it. Another important tip we can give you is to take care of your system and the software installed on it. Viruses like ransomware exploit weaknesses in them in order to infiltrate your computer, so make sure that you install updates, whenever those are available. Also, it’s vital that you have a functional antivirus program, which you should use to perform scans of your system on a regular basis. Investing in a reliable antimalware tool would also greatly contribute to an overall healthy PC and safe browsing experience.

To pay or not to pay

We mentioned that our guide would only attempt to restore the affected files, but we cannot promise that our method would necessarily be successful. This may lead you to debating whether or not it would be wise to pay the hackers the demanded amount and just be done with it. Well, here’s something to consider: these are people, who had the indecency and the nerve to break into someone else’s property, tamper with it and then try and blackmail the person for money. Does that sound like someone you would trust to do anything for you? And these aren’t just empty words; history has known its fair share of cases when ransomware victims were left with no decryption key after they had promptly transferred the requested amount. Not to mention that the ransom is often requested in Bitcoins, which are notoriously difficult to trace and provide the cybercriminals with the anonymity factor they so desperately need to keep their extortion scheme going. So there’s really no guarantee and no reason for the hackers to hold their end of the bargain.

    • Be sure to remove all of those IP’s since they are certainly not supposed to be there. Save the changes to the Hosts file after you delete the IP’s.

  • I called McAfee and they said it wasnt a virus. They said I had to contact HP. I asked “how can it be a PC problem? Maybe and OS problem. But a PC problem?” They said yes and ended the conversation. I just renewed my subscription. ggrrrrrrr.
    I updated and ran, both McAfee and Malwarebytes (both paid not free version)
    How do I know if it’s gone? I do know my myriad files still are gone and the Osiris file names are still there.
    I can’t go a registry edit. Too nervous. Are you saying I should disable my McAfee and download one of yours? and it WILL work? McAfee said there were 0 viruses.

    • We cannot give any guarantees about how effective that would be in your specific situation. Neverhteless, the scanner tool that we recommend to our readers is free so it will cost you nothing to download and install it and see if it detects anything. Also, even if nothing gets detected, you can still try the methods from the guide itself and see if that helps.
