PetrWrap Ransomware

PetrWrap Ransomware is a newly crafted file-encrypting malware. It goes without saying that you must avoid it at all costs if you consider yourself a security-conscious user. Having this malicious piece of software active for just a short period could have devastating outcomes as it is fully capable of locking huge chunks of personal data without any notification or authorization whatsoever. Like any other ransomware program, this one is crafted for a sole reason to profit illegally from Internet users. To learn how you can avoid any devious program and maintain a fully secure system at all times, make sure to read the rest of our report as we provide virtual security tips. We also present further information regarding overall functionality and origin of PetrWrap Ransomware with its detailed removal guide, which you should use without any hesitation if, unfortunately, you already have it active on your PC.

During an in-depth analysis of PetrWrap Ransomware, our research team has discovered that it is mainly based on another infamous program of the same category known as Petya Ransomware. As it turns out developers of PetrWrap Ransomware modified the binaries of its mentioned counterpart to fit their needs; thus their functionality is not completely identical. Right after this malicious program enters your PC, it scans your entire hard drive for its contents. As soon as it is done with that, it will start encrypting your personal files. The whole procedure is completely silent; thus, very few users are able to catch this malware in action. After it is done locking your data the malware in question damages your MBR (Master Boot Record). This means that each time you will start your PC it will load a ransom note instead of your operating system. The note informs you that your data has been encrypted. It also urges you to contact developers of this malicious program to purchase a key that should unlock your data and unlock your operating system. While some users might see this as a way to solve their problems, it must be stated that cyber crooks responsible for this ransomware are not obliged in any legal way to provide you with a legitimate key or any kind of decryption services even if you pay up. Thus, you might not only lose a huge amount of personal files but a large sum of money as well. To remove PetrWrap Ransomware entirely and to regain access to your computer, make sure to follow the instructions that we provide below.

To have a fully secure operating system at all times, you need to take precautionary steps. First of all, we advise you to install a professional antimalware tool, if you do not have one already. Such a tool is the most important part of your virtual security since it can automatically detect and warn you in advance about any suspicious program. Alongside such a tool we advise you to practice safe browsing habits just to be on a safe side. Since in quite a few cases malicious programs like PetrWrap Ransomware are spread via spam e-mail attachments, we highly advise you to refrain from all attachments that come your way form unknown sources. It is also important to note cyber crooks are known to exploit unsecured Remote Desktop Protocols to spread their devious program. Thus, if you have an RDP setup, make sure that it is fully secure at all times. Last, but not least, we highly recommend learning as much as possible in advance about the program that you want have to since malware developers are known to use manipulative marketing techniques to lure unsuspecting users into obtaining and installing their devious software. These seemingly simple preventative steps are extremely effective; thus, by taking them, you will make your operating system virtually unbreakable.

Under no circumstances delay the removal of PetrWrap Ransomware. Be sure to follow instructions that we present below with care because it is important to terminate this malware entirely for its devious functionality to stop altogether. Firstly, you will need to repair your MRB and only then will you be able to delete this malware. Once you are done, we highly advise you to double-check your operating system for any traces associated with PetrWrap Ransomware. This is important because its leftovers could prove to be more than enough for it to continue its malicious functionality. In other instances, such traces could prove to be enough to silently restore this malware. If you find such analysis of your PC a bit too complicated, you can scan your PC with a professional antimalware tool as it can detect and delete any traces associated with the ransomware in question automatically.
