Guesswho Guesswho is complex malware used primarily to keep a user from accessing their important information. The ultimate goal of Guesswho is to extort money from its victims by encoding their most used files and demanding a ransom payment for their decryption. A decryption key consisting of a private and a public code is the only way to decrypt the files that Guesswho has encrypted. Once the encryption process ends, the public code is given instantly. However, in order to obtain the private code of the decryption key, the victim must pay a ransom. If not, the hackers typically threaten to permanently erase the affected data or double the required ransom amount. If you have become a victim of Guesswho, you are not dealing with a regular virus but with a very sophisticated Ransomware infection. Therefore, the methods you should use to combat it should also be carefully selected. Moreover, unless you remove Guesswho from your computer, you most likely will be unable to create and store new files without them being encrypted instantly. That\u2019s why we suggest you study the information below and make an informed decision on what to do next. The Guesswho virus The Guesswho virus is a file-encrypting Ransomware designed to encode user data and keep it hostage for a ransom. The goal of the Guesswho virus is to make its victims pay a fixed amount of money to some anonymous cyber criminals for the restoration of the encrypted files. Ransom-demanding threats such as Guesswho, Nlah, Pezi could be distributed in several ways: by drive-by downloads, websites corrupted by malware, false notifications, malicious advertisements, infected torrents, video streaming pages, spam emails and even attachments that may come from a friend. The Guesswho file encryption The Guesswho file encryption is a stealthy process initiated by the Guesswho Ransomware. The purpose of the Guesswho file encryption is to convert the users\u2019 files into unreadable bits of data so that a ransom can be demanded for their decryption. Unfortunately, the Guesswho file encryption is not easily reversed. The decryption normally should be done using a special key that comprises of two elements \u2013 one public (accessible instantly) and one private, for which the victims are required to pay a ransom. If your files have been locked by Guesswho, you may think it's wise to simply pay the ransom. However, this is a dangerous option that puts at risk your money without a guarantee that your files will really be recovered. In the end, the crooks behind the Ransomware may disappear without sending you the private decryption key and you won\u2019t be able to do anything to get your money or your files back. Advising a professional, therefore, is a much cleverer idea. A person with some experience with such viruses may be extremely helpful and may be just what you need to successfully fight the Guesswho infection. In reality, however, contacting a professional may also be costly. Therefore, one of the most easily available alternatives is to use a free removal guide (like the one below) and try to remove the infection on your own.
