This article is designed to assist you to get rid .osiris file virus at no cost. Our recommendations describe the way how any files with .osiris extension can be decrypted.
The most critical thing here is certainly the point that the software program that is troubling you is Ransomware. Typically, it implies that its specific impact on your computer involves scanning your system and encrypting your data files.
Cyber criminals use plenty of ways to distribute ransomware viruses such as .osiris file virus.
Most often they launch spam campaigns and send millions of malicious emails all over the world. People receive unsolicited messages that contain infected attachments or just web links inside the body of the message.
In case users click on links or open attachments, virus drops its downloader somewhere in Temp folder. After that, this downloader starts to download the ransomware itself. Once the ransomware is on your computer, it begins to scan your system and encrypt all files.
Osiris ransomware uses several complex encryption mechanisms like AES and RSA to lock your files. It is very hard to decrypt files on your own. You can remove the virus by hand or use special security tools, but this will not decrypt .osiris files. Special steps should be taken to get your data back.
It is hard to advise people not to pay the ransom when you are not in their shoes, but you should really think twice before paying. Even if authors of .osiris ransomware send you the decryption key (which absolutely not guaranteed), the decryption process may glitch because in bad virus code or computer hardware failer. You may end up losing both money and files.
It is better to try all possible ways to remove ransomware and decrypt .osiris files. Out instructions are listed below.
Automatic removal of .osiris file virus
The benefits of using the automatic security suite to get rid of this infection are obvious: it scans the entire system and detects all potential fragments of the virus, so you are a few mouse clicks away from a complete fix.
- Download and install recommended malware security suite
- Select Start Computer Scan feature and wait until the utility comes up with the scan report. Proceed by clicking on the Fix Threats button, which will trigger a thorough removal process to address all the malware issues compromising your computer and your privacy.
Restore files locked by .osiris file virus
new Locky variant aka .osiris file virus represents a unique category of malicious software whose attack surface reaches beyond the operating system and its components, which is why removing the virus itself is a part of the fix only. As it has been mentioned, it encrypts one’s personal information, so the next phase of the overall remediation presupposes reinstating the files that will otherwise remain inaccessible.
-
Launch data recovery software
Similarly to the rest of its fellow-infections, .osiris file virus most likely follows an operational algorithm where it erases the original versions of the victim’s files and actually encrypts their copies. This peculiarity might make your day, because forensics-focused applications like Data Recovery Pro are capable of restoring the information that has been removed. As the virus further evolves, its modus operandi may be altered – in the meanwhile, go ahead and try this.

Take advantage of Volume Shadow Copy Service
This technique is based on using the native backup functionality that’s shipped with Windows operating system. Also referred to as Volume Snapshot Service (VSS), this feature makes regular backups of the user’s files and keeps their most recent versions as long as System Restore is on. .osiris file virus hasn’t been found to affect these copies therefore the restoration vector in question is strongly recommended. The two sub-sections below highlight the automatic and manual workflow.
- a) Use Shadow Explorer
Shadow Explorer is an applet that provides an easy way of retrieving previous versions of files and folders. Its pro’s include an intuitive interface where the computer’s entire file hierarchy is displayed within one window. Just pick the hard disk volume, select the object or directory to be restored, right-click on it and choose Export. Follow the app’s prompts to get the job done.
- b) Use file properties
Essentially, what the above-mentioned Shadow Explorer tool does is it automates the process that can otherwise be performed manually via the Properties dialog for individual files. This particular approach is more cumbrous but just as effective as its software-based counterpart, so you can proceed by right-clicking on a specific file, which has been encrypted by .osiris file virus, and selecting Properties in the context menu. The tab named Previous Versions is the next thing to click – it displays available versions of the file by date of the snapshot creation. Pick the latest copy and complete the retrieval by following the prompts.

Data backups work wonders
Ransomware like .osiris file virus isn’t nearly as almighty and destructive in case you run regular file backups to the cloud or external data media. The virus itself can be completely removed in a matter of minutes, and the distorted information can then be just as easily recovered from the backup. Luckily, this is a growing trend, so ransom Trojans are hopefully going to become less subversive in the near future.
Verify thoroughness of the removal
Having carried out the instructions above, add a finishing touch to the security procedure by running an additional computer scan to check for residual malware activity
